30+ AI SEO Statistics for 2026: Data on AI Overviews, ChatGPT & GEO
Cloudflare Radar: Perplexity now crawls 885 pages per visitor it sends back and Anthropic 823 - down by half. Plus SEOmator's own panel data and 30+ AI SEO statistics.
A Google AI Overview keywords checker that answers one question: does this keyword trigger an AI Overview right now, and which sources does it cite? Enter a keyword, pick from 213 countries and 129 languages, and get the overview Google generated plus every page it pulled from. Free, no account, live on every run.
Enter a keyword and we run a live Google search for it in the country and language you chose, then request that result page's AI Overview block the way a browser does — as a second, asynchronous load. Nothing comes from a stored index. Every run is a fresh, depersonalized search, so what comes back is what a signed-out searcher in that market would have seen at that moment, not what your own logged-in session shows you.
A question, a head term, a competitor's phrase — up to 200 characters. No URL, no account, no domain to verify, and no list to upload.
213 countries and 129 languages. AI Overview coverage is not the same in the US as in Germany, so the market is part of the answer rather than a setting you can leave alone.
You get a yes or no first. When an overview is present you also get the text Google generated and a numbered list of every source it cited, with title and publisher — the list you are trying to get onto.


Everything in this grid runs right now, with no sign-up and no credit card. The marked features are what a free SEOmator account adds.
No score, no probability, no "likely to trigger". The AI Overview block was in the result page or it was not, and that is what you get back.
The full answer, not our summary of it — so you can read which claims it made and check whether they came from your page or from someone else's.
A numbered list of the pages the overview pulled from, each linked. On an AI Overview SERP this is the ranking that matters, and it is the only one Google shows.
Run the same keyword for the US, Germany and India and compare. Coverage and the cited set differ by market more than most teams assume before they check.
Nothing cached. You see the SERP a signed-out searcher in that market gets, which is not the one your own logged-in browser has been personalizing for years.
There is nothing to verify and nothing to install, so a term a rival is chasing checks exactly as easily as one of your own.
One check is a snapshot. Tracking tells you whether an overview appears every day or flickers, and when the set of cited sources changed.
Get told when a tracked keyword starts or stops returning an overview, instead of finding out from a traffic chart a month later.
Keyword sets tracked together, and the site-wide crawl that shows whether your pages are structured to be quotable in the first place.

Sign up freeTwo things I want said before the pitch. This is a snapshot, not a rank. An AI Overview is generated per query, and Google's own documentation says the block is only shown when its systems judge it additive — so a keyword that returns an overview at 9am can legitimately return nothing at 11am. If a single check is the whole of your evidence, you have over-read it. And it is one keyword per run. There is no domain input and no bulk upload behind this form; the page used to claim otherwise, which is the main reason it was rewritten. What the check is genuinely good for is the part nobody else shows you: the cited list. When I ran "what is technical seo" for this page's screenshot, the overview cited ten sources — one of them a university, two of them YouTube videos, one of them Quora. That is a far more useful competitive set than a rankings table, because it tells you what kind of source Google decided to trust for that question. And the follow-up is reassuring rather than exotic: across the SERPs our rank tracker archives, 91.3% of AI Overview citations went to pages already ranking in the organic top 20 in the first half of 2026. You are not being asked to learn a new discipline. You are being asked to check which of your existing rankings now sit under an answer box.
91.3% of AI Overview citations we recorded in the first half of 2026 went to pages already in the organic top 20, and only 3.8% came from beyond the top 100. Your citation candidates are the terms you rank for today. Pull your top twenty from Search Console and run those first.
Across the keywords our rank tracker archives, 27.4% returned an AI Overview between 1 and 21 July 2026, up from 18.9% in January. The mix matters more than the average: SaaS and comparison queries ran near 34%, e-commerce product queries near 19%. If you sell software, plan for it. If you sell products, check before you panic.
Coverage is not stable, and a tool that pretends otherwise is lying to you. Two checks on the same day tell you whether you are looking at a fixed feature of that SERP or a coin flip — and that distinction changes whether the keyword is worth rewriting a page for.
A study of 405,576 AI Overviews found an average of five sources per answer. When you get back ten, or when half of them are forums and video, Google is telling you it could not find enough confident sources for that question. That is an opening.
The default is the United States in English, and it is the wrong default for most of the teams I talk to. Run your keyword for Germany in German and for the US in English and compare the two source lists. Different pages get cited, and often a different kind of page does.
Google's own documentation states there are no additional requirements and no special optimizations for appearing in AI Overviews. Use this check as a diagnostic — which of my pages sit under an answer box, and who is being quoted instead of me — and then fix the page with an ordinary site audit, not with AIO folklore.
Type it into the checker above, pick a country and a language, and read the answer. You get a yes or no, the overview Google generated, and a numbered list of every source it cited — which is the whole check, and it takes a few seconds.
There are three other ways people try to answer this question, and each of them fails in a specific way:
The check above does the thing none of those do: it runs the search from our side, signed out, in the market you name, and then requests the AI Overview block the way a browser does — as a second, asynchronous load. That two-step is worth knowing about, because it is the reason a result can differ from what your own browser paints.
Fewer than the discourse suggests, and the shape of the query matters more than the volume. Across the keywords our rank tracker archives, 27.4% returned an AI Overview between 1 and 21 July 2026, up from 18.9% in January 2026. Steady growth, not a cliff.
The average hides the useful part. Within the same panel, SaaS and comparison queries ran near 34% while e-commerce product queries ran near 19% — so "how much of my portfolio is affected" is a question about your query mix, not about the web.
Google's own documentation is unusually direct about the rule behind this: AI Overviews "are only shown when our systems determine that it is additive to classic Search, and as such, often don't trigger" (Google Search Central). Read that as a filter you can predict against. Queries where a synthesized paragraph beats a list of ten blue links — definitions, comparisons, multi-step how-tos, "best X for Y" — attract overviews. Queries where the user wants a specific page, a product, or a login do not.
| Query shape | Overview likely? |
|---|---|
| Definitions ("what is") | Very likely |
| Comparisons ("best X for Y") | Likely |
| Multi-step how-to | Likely |
| Branded / navigational | Rare |
| Product / transactional | Less common |
Because there is no list of AIO keywords for Google to look up. The block is generated per query, and the decision to show it is made per query too. A keyword that returns an overview at 09:00 can legitimately return nothing at 11:00, and neither result is a bug.
That volatility is not confined to presence. In our own AI visibility panel, the median week-over-week move in brand mention rate during quiet weeks was ±3.8 percentage points in the first half of 2026 — and around the two major model updates we detected in that period, 17% of tracked brands saw a swing larger than 20 points within a fortnight. The surface moves under you even when you change nothing.
The practical consequence is a habit, not a tool feature: run the check twice, a few hours apart, before you act on it. Two yeses mean the overview is a fixed feature of that SERP and worth planning a page around. A yes and a no mean you are looking at a coin flip, and rewriting a page to win a citation you may not be offered is a poor use of a quarter.
Start by counting. A study of 405,576 AI Overviews found an average of five sources per answer, with 78% of overviews containing a list of some kind. So five is your baseline, and a materially longer list is information.
The run captured for the screenshot on this page returned ten sources for "what is technical seo": Semrush, Michigan Technological University, GeeksforGeeks, two YouTube videos, NAV43, Search Atlas, Quora, e9digital and SEOBoost. That composition is the finding, not the count. Google reached for a university page, two videos and a forum thread to answer a question that dozens of SEO vendors have written about at length — which tells you it was not confident that any single vendor page was the definitive source.
Three things worth reading out of any list you get back:
On a SERP with an overview, the cited set is the visible hierarchy. A user who reads the answer and clicks a citation never sees position four. That is why the source list, not the presence flag, is the half of this tool worth building a workflow on.
Rank first. Across the SERPs our rank tracker archived in the first half of 2026, 91.3% of AI Overview citations went to pages already in the organic top 20, and only 3.8% came from beyond the top 100. Citation is overwhelmingly drawn from the pool of pages that already rank, so "how do I get cited" is mostly the old question wearing new clothes.
That is a more reassuring finding than it looks, because it means there is no separate discipline to learn. Google states it plainly: there are "no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary."
What does change is how the page has to be written. A summarizer has to be able to lift a passage from it without ambiguity. In practice:
Measure it rather than assume it. AI engines sent about 1.2% of all sessions across the sites we track in July 2026 — roughly double January's 0.62% — so this is the fastest-growing channel we measure and still a small one. It matters far more for some businesses than others: in the same month, B2B SaaS sites saw 1.6% of sessions arrive from AI engines against 0.7% for e-commerce.
So a citation is not a traffic strategy on its own. It is how you stay present on a result page where the answer arrives before the links do, and it earns you the visitor who wanted more than the summary gave them.
Two things are worth watching once you are in a list. First, whether you stay: re-check the keyword monthly, because the cited set changes without any ranking moving. Second, what the overview says about you — if the generated answer misstates your product or attributes your claim to someone else, that is a content problem you can only see by reading the overview text, which is why this tool returns it in full rather than a presence flag.
Both, and the second one is the more neglected.
Running a rival's target term costs you nothing — there is no domain to verify — and the cited list tells you something a rank tracker cannot: whether the query they are optimizing for still routes traffic to pages at all. A head term with an overview and ten citations is a different investment from the same term with clean blue links.
The market check is where teams are most often surprised. AI Overview coverage is not uniform across countries, and the sources Google trusts change with the language. Run your keyword for the United States in English and for Germany in German and compare the two lists: it is common for a localized page to face a SERP with different competitors, a different source mix, and sometimes no overview at all. That comparison is a two-minute job here and effectively impossible from a single browser.
Stated plainly, because the version of this page that ran until September 2026 claimed several of these:
| It does | It does not |
|---|---|
| One keyword, one market | Audit a domain or a list |
| Presence + overview text | Search volume or position |
| Cited sources, in full | Why a source was chosen |
| A live, signed-out check | The same result an hour on |
There is no bulk mode and no CSV upload behind this form. If you need a set of keywords watched continuously rather than checked by hand, that is what tracking in a SEOmator account is for. If you are still deciding which keywords are worth checking, start with the free keyword research tool or a Search Console export of the queries you already earn impressions on.
And if the question is broader than one keyword — how often does an AI answer mention us at all, across a category — this is the wrong instrument. The AI brand visibility checker measures mention share across AI answers, the AI Mode checker covers Google's separate conversational surface, and the GEO audit scores whether your site is structured to be quoted in the first place.
Rankings held, clicks fell, and the client wants a reason. Check the five keywords that lost the most and show whether an answer box now sits above the result — with the list of who is being quoted instead.
Before commissioning a page, check whether its head term returns an overview and what kind of source it cites. A question already answered by a university page needs a different brief from one Google answers out of forum posts.
Run the translated keyword in the target country and language. AI Overview coverage and the sources Google trusts vary by market, so a localized page can face a very different SERP from the English original.
Most free checkers stop at presence. The cited list is the actionable half — it names the pages Google chose over yours, which is the only competitive set that exists on an AI Overview SERP.
Every run is a fresh search, signed out. Checking in your own browser shows you a SERP shaped by your history and location; this shows you the one your market gets.
The market is a first-class input, not an assumption. That matters because AI Overview coverage is uneven across markets and the cited set changes with it.
The full result renders on the page. No email gate, no credit card, no trial that expires after three checks.
One keyword, one market, one moment in time, and no search-volume or position data. Every limit is stated here rather than discovered after you have trusted a number.
One of SEOmator's free SEO tools, alongside the AI Mode checker, the AI brand visibility checker and a full GEO audit.
It is a tool that runs a live Google search for a keyword and reports whether Google returned an AI Overview — the generated answer block above the classic results — and which sources that answer cited. It answers two questions you cannot reliably answer from your own browser: is this query being answered before anyone reaches a result, and if so, whose pages is the answer built from?
Type the keyword into the tool at the top of this page, choose the country and language you care about, and run the check. You get a yes or no, and when an overview is present, the text Google generated plus a numbered list of every source it cited. Checking in your own browser is the unreliable alternative: your results are personalized by history and location, and AI Overview coverage varies by market, so what you see is not what your audience sees.
It performs a live, depersonalized search for every run rather than reading a cached index, so the result reflects that market's SERP at that moment. What it cannot promise is stability: AI Overviews are generated per query, and Google's documentation states that they are only shown when its systems judge them additive to classic Search, so the same keyword can return an overview on one run and nothing on the next. Treat one check as a snapshot and run it more than once before you conclude a keyword is safe.
Because there is no fixed list of AIO keywords. Google decides per query whether an overview adds anything to the classic results, and that judgement moves with the query mix, the model, and what is available to cite. This is why the cited-sources list is more useful than the yes/no: presence tells you the state of one moment, but the sources tell you what kind of page Google currently trusts on that topic — which changes far more slowly.
Not with this free tool — it takes one keyword and one market per run, and it returns no search-volume or ranking-position data. That is a deliberate scope, and the page used to claim otherwise. If you need a keyword set watched continuously, that is what a SEOmator account's tracking is for; if you want to find the terms worth checking in the first place, start with the free keyword research tool or your own Search Console export.
Informational and comparison queries — "what is", "how to", "best X for Y" — far more than transactional ones. Across the keywords our rank tracker archives, 27.4% returned an AI Overview between 1 and 21 July 2026, up from 18.9% in January; within that, SaaS and comparison queries ran near 34% while e-commerce product queries ran near 19%. Your own mix matters more than any headline average, which is the reason to check rather than to estimate.
It is unlikely. Google's documentation is explicit that AI Overviews are only shown where its systems judge them additive to classic Search, and that they often don't trigger. Coverage across the keywords we track has grown steadily rather than sharply — from 18.9% in January 2026 to 27.4% in July — and it is concentrated in question-shaped and comparison queries rather than spread evenly across every search.
Start by ranking. Across the SERPs our rank tracker archived in the first half of 2026, 91.3% of AI Overview citations went to pages already in the organic top 20 and only 3.8% came from beyond the top 100. Beyond that, Google states plainly that there are no additional requirements and no special optimizations for AI features — the same fundamentals apply. In practice that means answering the question directly and early on the page, making the answer easy to lift as a passage, and being the kind of source a summary can safely attribute.
They are not alternatives — on most AI Overview SERPs the cited pages are also the ranking ones. The useful framing is that a citation is how you stay visible on a result page where the answer arrives before the links do. It is worth measuring rather than assuming: AI engines sent about 1.2% of all sessions across the sites we track in July 2026, roughly double January's share, and B2B SaaS sites saw more than double the rate of e-commerce sites.
A published study of 405,576 AI Overviews found an average of five sources per answer, though the number varies widely by query — the run captured for this page's screenshot returned ten. A long, mixed source list, especially one with forums and video in it, usually means Google could not find enough confident sources on the topic, which is a gap worth writing into.
There is no official setting that removes them permanently; the common workarounds are appending &udm=14 to a Google search URL to get the classic web results, or using a browser extension. Worth being clear about what that achieves, though: it changes what you see, not what your audience sees. That is exactly why a depersonalized check exists — your own filtered SERP is the least reliable place to judge whether a keyword has an overview.
Yes. An AI Overview is the generated block on a normal results page; AI Mode is a separate conversational surface, and Google says the two may use different models and techniques, so the links they show vary. A keyword can behave very differently in each. The free AI Mode checker covers that surface, and the AI brand visibility checker measures how often your brand is mentioned across AI answers rather than how one keyword behaves.
