The verdict

Most SE Ranking vs Semrush comparisons are written from the pricing pages. This one isn’t: I ran a month of real keyword research through SE Ranking instead of Semrush, audited my own site with both, and checked SE Ranking’s AI visibility numbers against five months of measurements I’d taken myself. Here’s what came out of it.

They disagree about search volume, by enough that it changes decisions. Same keyword, same day, same country.

SE Ranking’s audit crawls twice as deep and finds real problems Semrush misses — 352 dead URLs on my site that Semrush never reached. It also invented 349 sitemap errors that don’t exist, in the same report.

Its AI rank data is more honest than I expected. Tested against my own archive, it ranked SE Ranking third in SE Ranking’s own category. I went in looking for a cooked number and didn’t find one.

The AI visibility you meet first isn’t the good one. The tool in the main app answers the wrong question. The one that answers the right one is included in your plan, behind a separate login, and nothing points you to it.

The biggest practical difference isn’t features, it’s the export. Semrush hands you a sortable CSV. SE Ranking hands you a 166-page PDF.

After eight days of SE Ranking vs Semrush side by side, I’m sticking with Semrush, and the thing that decided it was the split.

I went into the last day expecting to keep both. What changed my mind was discovering that SE Ranking’s AI search capability lives in two places that don’t agree with each other — a domain-level tool inside the main app, and a far better prompt-level product behind a separate login that I only found by going looking. SE Visible is the one worth having. It isn’t the one you meet.

That’s a product decision, not a bug, and it’s the sort of thing that tells you how a tool will feel to use in six months.

Two things I’ll say for SE Ranking without qualification. The interface is cleaner. Semrush is cluttered with tools I can’t open on my plan, and SE Ranking is simply easier to move around in. And it crawls every URL on your domain against Semrush Pro’s 500-page ceiling, which on any site bigger than a few hundred pages is the difference between an audit and a sample.

If cost is a real constraint, those two advantages are worth more than anything Semrush offers at the entry tier.

How I ran this SE Ranking review

I run keyword research most weeks for my own site. On 1 November I signed up for SE Ranking’s trial and ran the same searches through both tools on the same day, starting with ai for small business — a keyword I’d already looked at in Semrush, so I knew what the answer was supposed to be.

Then I opened Google and Bing and checked whether either tool was telling me the truth.


The same keyword, two different answers

Here is ai for small business in both tools.

Semrush SE Ranking
US volume 4,400 2,400
Global volume 6,300 3,800
CPC $10.48 $6.60
Difficulty 62 / 100 77 / 100
Competition 0.13 0.04

Fig 1Semrush, 1 November 2026. Note the difficulty score: 62.
SE Ranking keyword overview showing 2.4K volume, 77 difficulty, $6.60 CPC
Fig 2SE Ranking, same keyword, same day. Volume is 45% lower and difficulty is 15 points higher. The date selector in the corner reads September — that’s the newest month the trial will show.

Semrush reports 83% more search volume, 59% higher CPC, and a lower difficulty score. Every number points the same direction: in Semrush, this keyword looks like a bigger, more lucrative, easier opportunity than it does in SE Ranking.

One caveat you need, because it’s the honest version. Semrush’s data is dated 1 November. SE Ranking’s trial serves September data and charges to see the current month — more on that below. I couldn’t align them, so treat the volume and CPC gaps as indicative rather than exact. Difficulty is the number that survives a two-month gap best, and that’s the one where the tools disagree most sharply: 62 against 77.

That gap matters more than it looks. If you’re choosing what to write based on Semrush’s numbers, you’re working from a more optimistic picture than SE Ranking would give you. Neither is lying. They’re modelling different things and neither tells you which one is closer to reality.

I ran three more keywords to see if it was a fluke

One keyword proves nothing, so I repeated it on three more — a high-volume term, a mid-volume one, and something small — on 8 November, both tools, United States, desktop.

Each line is one keyword; the dots are what each tool scored it. The direction flips, so neither tool is simply harsher — but on ai visibility tracker they are 54 points apart, which is the difference between “write this today” and “don’t bother.”

Semrush reported higher volume on all four. Not sometimes, not on average — every single one, by between 1.8× and 220×. That direction is systematic, and it’s the thing to take away: if you move from Semrush to SE Ranking, every keyword you look at will look smaller, and you will reject opportunities you’d previously have taken.

One of those numbers is simply wrong. SE Ranking puts semrush alternatives at 20 US searches a month. Its own global breakdown for the same keyword gives the UK 390 and France 320, with the United States at 1% of a 2,600 total. There is no world in which Britain searches for SEO-tool alternatives twenty times more than America does. That’s not a modelling difference, it’s a broken figure, and nothing in the interface flags it as low-confidence.

Twenty searches a month in the US, 390 in the UK. One of those is wrong.
Fig 3Twenty searches a month in the US, 390 in the UK. One of those is wrong.

Difficulty disagrees in both directions, so there’s no simple “SE Ranking is harsher” rule: +15, −12, +54, −3. But look at the third row.

The 54-point disagreement

On ai visibility tracker, Semrush says difficulty 10 — “Very easy. Your chance to start ranking new pages on Google as soon as possible without any backlinks.” SE Ranking says 64 — “NOT EASY. You will need a lot of high-quality referring domains and well-optimized content.”

Same keyword. Same day. Same country. One tool is telling me to write the article this afternoon and the other is telling me not to bother.

Semrush: KD 10%, 'Very easy'
Fig 4Semrush: KD 10%, “Very easy”
The same keyword, eleven minutes apart.
Fig 5The same keyword, eleven minutes apart.

This isn’t academic for me — ai visibility tracker is a term I’m actively planning content around, and these two tools give me opposite instructions.

So I went and looked at the actual Google results, which is the thing neither tool makes you do. The first page has a LinkedIn post at position 4 and a Quora question at position 6. When Google is padding a page-one with social posts, it hasn’t found authoritative pages to rank. On that evidence Semrush is closer to right, and SE Ranking’s 64 would have talked me out of a keyword I can win.

But notice what it took to settle it. I had to leave both tools and read a SERP by hand. If you take either difficulty score as given, one of them costs you the article.

What I’d actually conclude

Volume: Semrush runs consistently higher, so pick one tool and stay in it. Comparing a Semrush number from January against an SE Ranking number from March will tell you a trend that doesn’t exist.

Difficulty: treat both as a prompt to go look, not an answer. A 54-point spread on a keyword either of them could have scored correctly is not a rounding error, and the free check — open Google, look at who’s actually there — beats both.

One more thing worth flagging because it’s internally inconsistent rather than merely different: Semrush reports semrush alternatives at CPC $0 while simultaneously showing 4 active ads. Advertisers are not bidding nothing.


Neither tool shows you the real search results

This is the part that surprised me.

Both tools display a SERP overview — the pages currently ranking for your keyword. I pulled it in both, then opened Google in a browser and compared.

Bing, same query. A fourth different answer, with two sponsored results above the fold that neither tool surfaced.
Fig 9Bing, same query. A fourth different answer, with two sponsored results above the fold that neither tool surfaced.

Four different answers, and the two paid tools agree with each other more than either agrees with Google.

The part I got wrong the first time

I ran the live Google check twice: once signed in, once in a private window a few days later. The two didn’t match each other either. The first pass had muse.ai in the top four; the incognito pass doesn’t have it at all, and Reddit has moved up to the first organic position.

So the clean story — “the tools are stale, Google is the truth” — isn’t the story. The honest version is that nothing here is a stable reading, Google included. A cached index can’t match a live query, and two live queries days apart don’t match each other.

That’s still a problem for how the tools present the data. Both show you a SERP overview as though it’s the current page. It isn’t a lie, but it is a snapshot with no timestamp on it, and if you’re sizing up who you’d compete against, you’re planning against a page that has already moved.

Two things the live check showed that neither tool did

Reddit owns the top organic result. Not a tool vendor, not a guide — a four-day-old r/AI_Agents thread with 50+ comments, with a second Reddit block further down under “Discussions and forums.”

That lines up with something I found independently in SE Visible’s Sources panel further down this page, which reported Reddit as the single largest source behind AI answers in my category at 15%. Two unrelated measurements, same conclusion: in this space, Reddit is the competitor. Neither keyword tool told me that.

The commercial intent is for services, not software. Google’s “related products & services” block returns AI consulting firms near me, AI small business consulting services near me, small business AI certification programs. People searching this term are substantially looking to hire someone, not to buy a tool. That reframes the $10.48 CPC: you’re bidding against consultants, which is why it’s expensive and why a software review may convert badly against it.

Neither Semrush nor SE Ranking surfaced that, and it’s the single most useful thing I learned from thirty seconds in a browser.


Where SE Ranking is better

Two things, and the second one is the reason to read this page at all.

Ad spend data. For the same keyword, SE Ranking shows what advertisers are running and what it’s costing them. Semrush shows an ad count — 14 — and stops. If you care about commercial intent, seeing the actual ads tells you more than a number does.

API access at a quarter of the price. This is the one nobody mentions.

Cheapest plan with API
SE Ranking Core — $129/mo, 25k credits included
Semrush Business — $499.95/mo
Semrush SEO Classic plans: Pro $139.95, Guru $249.95, Business $499.95
Fig 11API access appears only on Business, at $499.95.
SE Ranking plans: Core $129, Growth $279
Fig 12SE Ranking Core, $129, includes API access with 25k credits — and AI visibility tracking across 5 engines.

Semrush Pro at $139.95 doesn’t include API access. Neither does Guru at $249.95. You need Business. SE Ranking includes it in their entry tier at $129.

I hit this wall myself before running this test: I wanted to query Semrush programmatically, found out Pro doesn’t allow it, and the upgrade path was $360 a month. If automating any part of your workflow matters, this single line is the whole comparison.

And AI visibility really is bundled — in both forms. This took me three attempts to get right, which tells you something about how SE Ranking presents it.

There are two separate AI products. AI Search is the domain-level tool inside Competitive Research. SE Visible is the prompt-level product, with its own app, its own login and its own standalone pricing — $89, $189 or $399 a month if you buy it on its own.

But you don’t have to. Core at $129 includes SE Visible: 25 prompts a day across 5 AI engines. So does Growth at $279. The standalone tiers exist for people who want AI visibility tracking without an SEO platform, and they buy capacity — 75, 200 or 1,000 continuously tracked prompts — rather than access.

That makes SE Ranking’s bundling claim true, and it’s a real advantage. Semrush sells AI Visibility as a separate toolkit on top of the SEO plans.

If AI visibility is the reason you’re here, that’s the strongest single argument for SE Ranking’s Core plan: you get the SEO platform and the prompt-level tracker for $129, where the equivalent from Semrush is two purchases.

The catch is discoverability, not money. SE Visible needs a second signup, lives at its own address, and nothing in the main app walks you to it. I nearly published a review saying SE Ranking couldn’t do prompt-level tracking at all, having paid for a plan that includes it.

But “AI visibility” means two different products here, and that trips up every comparison article I read, including the first draft of this one.

AI Search SE Visible
Where Competitive Research, in the main app Separate product, separate signup
Input a domain a brand, then editable prompts
Engines ChatGPT, Gemini, Perplexity, AI Overviews, AI Mode ChatGPT, Gemini, AI Overviews, AI Mode, Copilot
Answers which question how visible is this domain who gets named when someone asks X
Limit on trial 3 reports/month 20 prompts × 3 engines

They don’t even cover the same engines. AI Search queries Perplexity; SE Visible doesn’t. Neither queries Claude. Same vendor, two AI visibility products, two different definitions of “AI search.”

If you’re evaluating SE Ranking for AI visibility, that distinction is the whole decision, and nothing on the pricing page makes it.


I checked their AI visibility numbers against my own

This is the part I could do that a desk reviewer couldn’t.

Since July 2026 I’ve run the SaaSArc AI Visibility Index — a monthly measurement that asks four AI engines (ChatGPT, Gemini, Perplexity and Claude) the same set of questions across 25 software categories and records which products get named. Five months of archived responses, same prompts every month. Two of those questions are about SEO tools.

That gives me an independent answer to the question SE Ranking’s AI Search feature is selling: which SEO tools actually get cited by AI engines, and in what order.

I wrote the prediction down first

Before opening the tool, here’s what five months of my own data said the ranking should be, measured as share of citations in my SEO category:

My index, 5-month average
Semrush 38.0%
Ahrefs 33.0%
SE Ranking 18.0%
Moz 11.0%

Semrush has been first in my index every month for five consecutive months. SE Ranking has never once been cited by all four engines in the same run.

So the test had a specific, falsifiable shape: does SE Ranking’s own tool report SE Ranking as a distant third? A vendor tool has an obvious incentive not to.

What it reported

AI Search is domain-based — you enter a domain, not a prompt — and it returns a “Topic Presence” table broken out by subject. The row that matches my SEO questions is Keyword Research Tools. Normalising those figures across the same four brands:

SE Ranking’s tool My index (Nov) My index (5-mo avg)
Semrush 51.4% 40.0% 38.0%
Ahrefs 28.5% 35.0% 33.0%
SE Ranking 12.3% 20.0% 18.0%
Moz 7.8% 5.0% 11.0%

Rank order matched exactly. Semrush, then Ahrefs, then SE Ranking, then Moz — in their measurement, in my November run, and in my five-month average. Three independent orderings, no disagreement.

And it didn’t flatter itself. SE Ranking’s own tool reports seranking.com at 6.97% raw presence against Semrush’s 29.11% — under a quarter of the market leader, and less than half of Ahrefs. I went in expecting the vendor’s own entry to be the one number I couldn’t trust. It wasn’t. That deserves saying plainly, because it’s not what I predicted and it’s not the norm.

Where we disagree: spread, not order

Their distribution is more top-heavy than mine. Semrush leads Ahrefs by 1.80× in their data and 1.15× in mine; Semrush leads SE Ranking by 4.18× against my 2.11×.

That’s a methodology difference, not a contradiction. They sample many prompts and report a share; I ask two specific questions across four engines once a month, which is coarse and compresses the gaps between adjacent tools. Neither number is wrong. Rank order is the part that’s comparable, and rank order agreed.

The numbers are internally consistent

Worth noting because the site audit wasn’t. I ran two separate reports — one with semrush.com as the main domain, one with ahrefs.com — and the overlapping figures were identical across both: ahrefs.com at 16.14%, backlinko.com at 2.22%, neilpatel.com at 3.62%. Same values, different query.

That’s a stable underlying dataset. Compare it to the site audit section above, where the same site returned different page counts between crawls. Same vendor, two features, very different reliability.

Three things it gets wrong

AI Search is domain-only. You can ask how visible a domain is. You cannot ask who gets named when someone asks a specific question — and for GEO work the second question is the one that matters. It tells you that you’re visible, not what you’re visible for, and only the second is actionable.

This is a criticism of AI Search specifically, not of SE Ranking’s AI tooling as a whole. SE Visible does answer the prompt-level question, and I’ve written that up below. But the two don’t talk to each other, and the one bundled into the plans you see on the pricing page is this one.

The headline metric is uninterpretable. The dashboard leads with “Overall Presence: 0.1%” for semrush.com — the most-cited SEO tool in my entire five-month dataset. The denominator isn’t disclosed and is evidently enormous. “Mention Presence” returned No data outright. The number that actually works is buried in the Topic Presence table at the bottom of the page.

Three reports a month on trial. I used all three in one sitting: semrush.com, ahrefs.com, and one spent before I understood the limit. For a feature positioned as a headline reason to buy in 2026, three domains a month is restrictive — and it’s a hard stop, not a throttle.

What this is worth

On the evidence: the measurement is sound, the ranking is right, and the vendor doesn’t cook its own number. That’s better than I expected and better than I can say for their site audit.

But it’s a scoreboard, not a tool. It tells you where you stand; it doesn’t tell you which questions you’re losing or what to write to fix it. If AI visibility is why you’re considering SE Ranking, understand you’re buying a measurement, not a method.


SE Visible is the better product, and it’s hidden

The prompt-level tracking I just said was missing does exist. It’s in a separate product, behind a separate signup, which is why I nearly published a review saying SE Ranking couldn’t do this.

A second account, for a tool inside the product you already pay for.
Fig 13A second account, for a tool inside the product you already pay for.

The onboarding is the best thing SE Ranking does

You give it a domain. It reads your site — it told me it had read 161 KB of HTML from my homepage and About page — and comes back with what it thinks you sell.

For saasarc.com it returned five things: AI tools directory, hands-on tool reviews, SaaSArc AI Visibility Index, GEO and AI search guides, sponsored listings and featured placements.

That’s close to exactly right, and one of those is a monthly research project of mine that no database has an entry for — it exists only on this site. It read the page and worked it out. I’ve onboarded a lot of SEO tools and none of them has done that.

Auto-discovered from my site. It found the Visibility Index on its own.
Fig 14Auto-discovered from my site. It found the Visibility Index on its own.

It then proposes competitors — it picked There’s An AI For That, Futurepedia, ToolDirectory.ai, Quarule and Toolify, which is the right peer set — and writes a starting prompt list. Everything is editable, one prompt per line.

20 prompts across 5 topics and 3 engines. All of it editable.
Fig 1520 prompts across 5 topics and 3 engines. All of it editable.

Total setup: about ten minutes, most of it waiting.

Then it measures the wrong thing

Here’s where it comes apart, and it’s a more interesting failure than a broken feature.

It correctly worked out that I publish reviews of AI tools. Then it generated prompts like “What are the best AI writing tools available right now for content creation?” and “How do the top AI image generators compare in terms of quality and pricing?”

Those questions surface the tools. They cannot surface a site that reviews the tools. The answer to the first one came back “the strongest AI writing tools are Claude, ChatGPT, Gemini, Grammarly, Jasper, and Sudowrite” — correct, useful, and structurally incapable of ever containing my brand.

So the opening dashboard reads 0% visibility, 0% share of voice, no sentiment data — and every competitor it picked also reads 0%. Futurepedia and There’s An AI For That are far bigger than me, and they’re on zero too. When a measurement puts an entire peer set at zero, the prompts are wrong, not the industry.

Me and five competitors, all at zero. The prompts can't surface any of us.
Fig 16Me and five competitors, all at zero. The prompts can’t surface any of us.

One prompt in the set is the right shape — “Finding a reliable, honest review of an AI marketing tool can be tricky because much of the internet is flooded with AI-generated listicles and affiliate blogs…” — and I’m not in that answer either. That one’s a real result, and a useful one. It’s the question I should be winning and I’m not.

The fix is to rewrite the prompts, which takes five minutes. But the tool wrote them, presented them as researched, and a user who trusts the default will measure nothing for a month and conclude AI search doesn’t matter for their business.

The Sources panel is the thing actually worth paying for

Buried under the empty charts is the most useful screen in either product: which domains AI engines pull from when answering questions in your space.

Source Coverage AI answers
reddit.com 15% 9
zapier.com 10% 6
youtube.com 10% 6
medium.com 6.7% 4
semrush.com 6.7% 4

That’s actionable in a way nothing else here is. It doesn’t tell me my score, it tells me where the answers come from — and in my category the answer is Reddit, by a distance. No amount of on-page work competes with that, and I wouldn’t have known it without this panel.

The “Cited” column does not mean what it says

In the answers table, every row reads Mentioned: No and Cited: Yes at the same time, while the dashboard above reports 0% visibility. Three things that can’t all be true of the same brand.

Every row. Alongside a 0% visibility score.
Fig 17Every row. Alongside a 0% visibility score.

So I exported the raw data, and the export settles it. The underlying field isn’t called “Cited” — it’s called Has Urls, and it’s Yes on 54 of my 60 rows.

It means the AI’s answer contained links. Any links. To anybody. It has nothing to do with whether your brand was cited. The column that actually answers that question is Has Mentions, and mine reads No on all 60 rows, which matches the 0% score exactly.

Renaming Has Urls to “Cited” in the interface is not a cosmetic problem. A user glancing at that table sees their brand marked Cited: Yes on nearly every answer and concludes they’re doing well in AI search. The opposite is true, and the correct number is in the same table one column to the left.

Two more problems surfaced in the same export. The column headed Prompt doesn’t contain prompts — it contains the full text of the AI’s answer, with the actual prompt nowhere in the file. And the export is named for a week-over-week comparison (2026-11-02_2026-11-08_vs_2026-10-26_2026-11-01) while every one of its 60 rows carries the identical timestamp, 2026-11-08 14:01:54. There’s one batch of data in there and no comparison at all.

That last one has an innocent explanation — I’d signed up that morning, so there was no previous week to compare against. But the file is still named as though there were, and nothing in it says the comparison is empty.

What SE Visible is worth

It’s the better of the two AI products and it’s the one you have to go looking for. The site-reading onboarding is genuinely ahead of anything else I’ve used. The Sources panel answers a question I’d otherwise pay a consultant for.

But it ships with prompts that measured nothing for my business, and it’s sold as a separate product with its own signup, which means the AI visibility you’re buying on the pricing page is the weaker one.


SE Ranking pricing vs Semrush pricing: the “cheaper alternative” framing is wrong

Every comparison article calls SE Ranking the budget option. Open both pricing pages on the same day and that falls apart.

Semrush SE Ranking
Entry Pro — $139.95 Core — $129.00
Mid Guru — $249.95 Growth — $279.00
With API Business — $499.95 Core — $129.00

SE Ranking is $11 cheaper at entry and $29 more expensive in the middle. It isn’t a discount version of Semrush. It’s a different bundle: more capacity and API and AI visibility lower down the ladder, fewer of the content and multi-location tools Semrush puts in Guru.

Which is cheaper depends entirely on what you need. If you want API access, SE Ranking Growth at $279 beats Semrush Business at $499.95 by 44%. If you want to monitor fifteen sites and don’t care about API, Guru is the cheaper plan.


You can’t compare these fairly on a trial

Worth its own section, because it’s the situation you’re probably in right now.

Both tools paywall the exact data you’d need to check them against each other — in opposite directions.

SE Ranking’s trial serves September data. Changing the date returns: “Historical data is limited under your current pricing plan.” So the trial shows you two-month-old numbers and asks you to pay for the current month.

SE Ranking's trial, asked for a different month.
Fig 18SE Ranking’s trial, asked for a different month.

Semrush Pro serves current data and gates the past. Trying to look back gets you a modal: “Get more with Guru plan — historical data.” $110 a month more.

Semrush Pro, asked for the same thing. Opposite gate, same outcome.
Fig 19Semrush Pro, asked for the same thing. Opposite gate, same outcome.

So on a paid Semrush plan and a free SE Ranking trial, there is no month where both tools will show you the same period. I could pay one of them to fix it. That is, presumably, the idea.

A small thing I noticed while hitting that wall: SE Ranking’s upgrade prompt tells you to move to the “Business plan,” but their pricing page lists Core, Growth and Enterprise. Their own paywall names a tier that doesn’t exist.


Setting it up

SE Ranking’s onboarding asks for your URL, then runs a crawl and proposes competitors and keywords before you’ve touched anything. For saasarc.com it surfaced five competitors — max-productive.ai, superprompt.com, toolskit.net, aiunderstanding.org, launched.tools — of which only one shared more than a handful of keywords with me.

Five suggested competitors. Four of them share 1, 3, 5 and 0 keywords with my site.
Fig 20Five suggested competitors. Four of them share 1, 3, 5 and 0 keywords with my site.
Some are real targets of mine. 'Twin pic' and 'mars code' are not.
Fig 21Some are real targets of mine. “Twin pic” and “mars code” are not.

The suggested tracking keywords were a mixed bag. Some were clearly drawn from my actual content: how to track brand mentions in ai search and ai search optimization platforms, both real targets of mine. Others — twin pic, octopus web, mars code — I can’t account for at all.

The dashboard after setup was almost entirely zeroes: 0 organic traffic, 0% search visibility, 0% AI presence, 0 ranked keywords in the top 100. For a site with 445 referring domains and 35 ranking keywords, that’s a jarring first screen.

Fig 22Zero mentions across AI Overview, AI Mode, ChatGPT, Gemini and Perplexity. I have independent data on this and test it in the AI visibility section below.

It was the crawl, not the verdict. I checked the same dashboard a week later and it had filled in: average position 76, three keywords in the top 30, thirteen in the top 100, and five keywords flagged as having jumped — including ai search optimization platforms with best data history at position 14.

Average position 76, 13 keywords in the top 100. The zeroes on day one were an unfinished crawl, not a measurement.

So the first screen is misleading rather than wrong, and that’s a fair thing to hold against it: nothing on day one tells you the numbers aren’t ready. A new user looking at 0% search visibility for a site with 445 referring domains has no way to know whether the tool is still working or has just delivered bad news.

AI presence stayed at 0% across all five engines in both checks, which matches my own measurements.


The site audit test: 3 broken pages, or 352?

I pointed both audits at saasarc.com on the same day. This is where the comparison stopped being academic.

Semrush Pro SE Ranking Core
Pages crawled 500 1,000
URLs discovered not reported 2,143
4XX errors found 3 352
Health score 75 69

Semrush crawled exactly 500 pages. That is my plan’s cap, not a property of my site. It stopped when the allowance ran out and handed me a health score of 75.

SE Ranking crawled a thousand and found 352 URLs returning 404 — mostly leftovers from my old Wix site, image paths like /4c7dbe_[hex]mv2/, each one duplicated with a -1 suffix by WordPress during the import.

I verified a sample myself through httpstatus.io. They return a genuine HTTP 404. SE Ranking was right and Semrush never looked.

That is the lesson, and it isn’t “SE Ranking is better.” A plan limit doesn’t warn you. It returns a clean report on a partial crawl, and nothing in the Semrush interface says “I stopped early, there may be more.” On a bigger Semrush plan the two audits would likely agree. If your site has more pages than your plan crawls, your audit is a sample being presented as a survey.

I searched all six child sitemaps. None of those URLs are in any of them.

The same crawl that found 352 real problems Semrush missed also invented 349 that were not there.

Then SE Ranking reported 349 problems that don’t exist

Its top-issues list says 349 4XX pages in XML sitemap. A sitemap advertising dead URLs would be a real problem, so I went looking.

My sitemap index has six child files: posts, pages, listings, categories, listing categories, authors. I searched every one of them for those URLs. None of them are in any sitemap. Semrush, crawling the same site, also found no such sitemap entries.

The number underneath it is the tell. SE Ranking reports 349 4XX pages in the sitemap and 348 noindex pages in the sitemap. One apart. My listing pages genuinely are noindexed and genuinely are still in the sitemap, so that second figure looks real — and the first appears to be the same set of URLs counted again under a label that doesn’t fit them.

So in a single report, SE Ranking found 352 broken pages Semrush missed entirely, and invented 349 sitemap errors that aren’t there. Both of those are worth knowing before you act on either.

What each one is better at

SE Ranking crawls far deeper. Core allows 250,000 pages a month against Semrush Pro’s 500-page audit. On any site above a few hundred pages, that gap decides which tool can see your problems at all.

Semrush exports. It gave me a CSV with one row per URL — status code, crawl depth, incoming internal links, load time, sitemap membership. I could sort and filter it in ten seconds. SE Ranking gave me a 166-page PDF with no export option, with the 352 URLs printed as a list across eleven pages. You cannot work with that.

Semrush measures performance. Median page load 1.14 seconds, crawl depth distribution across five levels. SE Ranking’s Core Web Vitals panel reads “NO RESULTS FOUND.”

And SE Ranking’s dashboard has visible bugs. “Pages in Google” and “Pages in Bing” both display NaN — a JavaScript error rendered straight into a paid report.

One thing I still can’t explain. If those URLs aren’t in my sitemap, SE Ranking found them somewhere else. The likeliest answer is that posts imported from an older Wix site still carry image tags pointing at dead paths, which would make the URLs real and the “in XML sitemap” label wrong rather than the whole finding wrong. I haven’t confirmed it, and I’d rather say so than guess in print.


Pros and cons

Everything here is from the test above. Nothing is from a feature list.

SE Ranking — what’s genuinely good

It crawls deep enough to find your actual problems. 1,000 pages on trial against Semrush Pro’s 500, and 250,000 a month on Core. It found 352 dead URLs on my site that Semrush never saw, because Semrush never got that far. Their free trial crawls 1,000 pages without a card, which is enough to tell you whether your own audit has been lying to you.

API access at the entry tier. $129 on Core. Semrush wants $499.95 for Business. If any part of your workflow is automated, this one line is the whole comparison.

Its AI rank data is honest, including about itself. I checked it against five months of my own measurements. It put SE Ranking third in its own category, behind Semrush and Ahrefs. I expected a flattering number and didn’t get one.

SE Visible’s onboarding is the best I’ve used. It read my site and correctly identified five things I do, including a monthly research project no database has an entry for.

The Sources panel is the single most useful screen in either product. It told me Reddit accounts for 15% of AI answer sources in my category. Nothing in Semrush told me that.

The interface is cleaner and easier to navigate. This sounds like a soft point and it isn’t. I spent a month in both. SE Ranking is laid out so you can find things; Semrush is a wall of tools, many of which I can’t open on my plan.

SE Ranking — what’s wrong with it

It invented 349 sitemap errors. It reported “349 4XX pages in XML sitemap.” I searched all six of my child sitemaps. None of those URLs are in any of them.

The audit is unstable. Page counts changed between crawls of the same site on the same day.

There are visible bugs in paid reports. “Pages in Google” and “Pages in Bing” both render NaN. Core Web Vitals reads “NO RESULTS FOUND.”

A column in SE Visible is labelled so badly it inverts the answer. “Cited: Yes” on 54 of my 60 rows means the AI’s answer contained links — to anyone. Not to me. The field that tracks whether I was cited reads No on all 60.

No audit export. A 166-page PDF with 352 URLs printed across eleven pages, and no CSV. Semrush handed me a sortable file in one click.

The AI visibility story is split across two products that don’t agree. AI Search is domain-only and sits in the main app; SE Visible is prompt-level, far better, and hidden behind a separate signup you have to go looking for. They cover different engines. Neither covers Claude. Both are included in your plan, which makes the discoverability failure worse, not better — you’re already paying for the good one.

SE Visible shipped me prompts that measured nothing. It auto-generated questions that structurally cannot surface a review site, then reported 0% for me and 0% for every competitor it picked.

The paywall names a plan that doesn’t exist. It told me to upgrade to the “Business plan.” Their pricing page lists Core, Growth and Enterprise.

The trial serves September data and asks you to pay for the current month.

Semrush — what’s genuinely good

Exports. One row per URL, with status code, crawl depth, internal links, load time and sitemap membership. Sortable in ten seconds.

Performance data that exists. Median load time, crawl-depth distribution. The panel SE Ranking leaves empty.

It reports current data on the entry plan. SE Ranking’s trial doesn’t.

One AI product, not two sold separately under similar names.

Semrush — what’s wrong with it

The 500-page audit limit on Pro, with no warning. It returned a clean health score on a partial crawl and said nothing about stopping early. That’s worse than a low limit: it’s a sample presented as a survey.

API only at $499.95. Nearly 4× SE Ranking’s entry tier.

Historical data is gated behind Guru at $110 a month more.

AI Visibility is a separate purchase. SE Ranking includes it; Semrush doesn’t.

The interface is cluttered with tools I can’t use. A large share of what Semrush puts in front of me on Pro is locked behind Guru or Business. Every one of those is a thing to scroll past, and it’s the main reason SE Ranking felt easier to work in.


Who should use which

If you’re a blogger or a small business who needs general keyword research and site audits, SE Ranking is the better buy and it isn’t close. You get an audit that reaches your whole site, an interface you can navigate without hunting, API access at the entry tier, and AI visibility tracking included. At $129 it does more of what you’ll actually use than Semrush Pro does at $139.95.

If you’re an experienced SEO or a large organisation where $360 a month isn’t the deciding factor, Semrush wins. The data is more workable, the exports are real, and you’re past the point where crawl limits bite because you’re on a plan that doesn’t have them.

The export gap is what decides it between those two poles. Semrush hands you a CSV with one row per URL. SE Ranking hands you a 166-page PDF. If you work with audit data rather than just reading it, that one difference outweighs the crawl depth.

If you’re buying for AI visibility specifically — the reason most people are looking at SE Ranking in late 2026 — buy it, but know you’ll be using SE Visible rather than the AI Search tool in the main app, and that you’ll have to go and find it. It’s included in your plan at 25 prompts a day. It’s also the better product by a distance.

Don’t buy either on a trial expecting to compare them. You can’t. SE Ranking shows you September; Semrush Pro won’t show you anything but now. There is no month where both will show you the same period unless you pay for one of them.


Cancelling

Short section, because it was a short process, and because every review that skips it is leaving out the thing you’ll want to know in thirty days.

Profile menu → Billing → and you land on the plan selection screen. On a trial that’s where it ends: there’s no subscription to stop, so the page simply offers you the tiers. With an active subscription this is where the cancellation prompt appears.

No retention maze, no support chat, no three-screen “are you sure.” Two clicks to the right page.

One honest limit on that finding: I tested this on a free trial, so I never confirmed a real cancellation. What I can report is that the path is two clicks and obvious, which is already better than a lot of SaaS billing pages. What happens after you click cancel on a paid plan, I can’t tell you.

Questions people ask about this comparison

Is SE Ranking better than Semrush?
Neither wins outright. In an eight-day SE Ranking vs Semrush test on the same site and the same keywords, SE Ranking crawled twice as deep, cost less at the entry tier, included API access and AI visibility tracking, and had the cleaner interface. Semrush gave more workable data, real CSV exports and current rather than month-old figures. For a blogger or small business doing keyword research and site audits, SE Ranking is the better buy; for anyone working with the data daily, Semrush is.
Is SE Ranking cheaper than Semrush?
Only at the entry tier. SE Ranking Core is $129/month against Semrush Pro at $139.95. In the middle SE Ranking is more expensive: Growth is $279 against Semrush Guru at $249.95. The real saving is API access, which SE Ranking includes at $129 while Semrush requires the $499.95 Business plan.
Do SE Ranking and Semrush report the same search volume?
No. Across four keywords tested on 8 November 2026, Semrush reported higher US volume on all four, by between 1.8x and 220x. For ‘ai for small business’ Semrush showed 4,400 and SE Ranking 2,400. For ‘semrush alternatives’ Semrush showed 4,400 and SE Ranking showed 20, which appears to be a data error since SE Ranking gives the UK 390 for the same term.
Which tool has more accurate keyword difficulty?
Neither is consistently right. Across four keywords the difference ran +15, -12, +54 and -3, so there is no simple rule. On ‘ai visibility tracker’ Semrush scored 10 (‘very easy’) and SE Ranking scored 64 (‘not easy’). Checking the live Google results settled it: a LinkedIn post ranked 4th and a Quora question 6th, which supports Semrush’s low score.
Does SE Ranking include AI visibility tracking?
Yes. SE Ranking Core at $129/month includes SE Visible with 25 prompts a day across 5 AI engines, and so does Growth at $279. SE Visible is also sold standalone at $89, $189 or $399 a month for more tracked prompts. Semrush sells AI Visibility as a separate toolkit on top of its SEO plans.
What is the difference between SE Ranking’s AI Search and SE Visible?
They are two different products. AI Search sits inside Competitive Research, takes a domain rather than a prompt, and is capped at 3 reports a month on trial. SE Visible is a separate product with its own signup that tracks user-written prompts. They do not cover the same engines: AI Search queries Perplexity and SE Visible does not, SE Visible covers Copilot and AI Search does not, and neither covers Claude.
Which tool is better for site audits?
SE Ranking crawls deeper and Semrush exports better. On the same site SE Ranking crawled 1,000 pages and found 352 dead URLs; Semrush stopped at its 500-page Pro limit and found 3. But SE Ranking also reported 349 sitemap errors that do not exist, and delivers results as a 166-page PDF with no CSV export.
Can you compare SE Ranking and Semrush properly on a free trial?
No. SE Ranking’s trial serves September data and charges for the current month, while Semrush Pro shows current data and gates historical data behind the Guru plan. There is no month in which both tools will show you the same period unless you pay for one of them.
