Search Console's Generative AI report: what it shows, and the four questions it can't answer

Google's documentation is unusually plain about the scope. The report shows, in Google's words, "how your site performs in generative AI features on Google Search" — organic impressions over time, your top-performing pages, and impressions broken down by device or country. Two surfaces are in scope: AI Overviews and AI Mode. The data comes from the Web search type in the Performance report, so it sits alongside the numbers you already read rather than replacing them. Google notes: "As of August 31, 2026, we've rolled out these insights to all websites worldwide." What is out of scope is stated just as plainly. Search Console "doesn't include data from experiments in Search Labs, as these experiments are still in active development", and Discover has its own separate report. Google also names two reasons your site may show nothing at all: you have excluded your site from Search generative AI features, or it "hasn't received enough impressions in generative AI features on Google Search". Read that last line carefully, because it is the difference between a measurement and a conclusion. A blank report means Google has not recorded enough impressions to show you. It does not mean nobody is being shown.

An impression is an appearance, not an endorsement. The report counts times a link to your site appeared in a generative AI feature. It does not tell you what the answer said about you, whether your brand was named in the prose, or whether you were the recommendation or the counterexample. A page can be linked underneath an answer that recommends somebody else. It is a Google report, about Google. AI Overviews and AI Mode are two surfaces among many. Nothing in this report knows what ChatGPT, Claude, Perplexity or Microsoft Copilot said about you this morning. If your buyers research in an assistant rather than in a search box, this report is silent on most of their journey. An empty report is ambiguous by design. Google gives two documented reasons for no data, and only one of them is about your visibility. Treating a blank screen as a zero is the single most common error we see, and it is the same mistake as reading a tool's missing data as a measured zero.

These are not criticisms of the report. They are structural: the report is built from Google's own serving logs, so it can only know what Google served. Did the other assistants name you? Google's report covers Google's surfaces. ChatGPT, Claude, Perplexity and Copilot each compose answers from their own retrieval, and none of it passes through Search Console. Were you named without being linked? Being cited and being named are different wins. An answer can recommend you by name in the prose without linking you, which earns you the buyer and no impression anywhere. It can also link you as a source while recommending a competitor in the sentence above. An impressions report cannot separate those two, and they call for opposite fixes. What did the assistant search before it answered? Most assistants run their own web searches first, and several expose them. Over the 90 days to 23 September 2026 we captured this on our own brand's prompts: 427 answers, of which 323 exposed the searches they ran — 521 distinct searches in total. ChatGPT, Claude and Gemini expose theirs; AI Overviews, AI Mode and Perplexity do not. Reading them is uncomfortable and useful in equal measure, because they are the questions the machine thinks it needs answered, in its own words. Who was recommended instead of you? The report has no competitive dimension. It cannot tell you that a particular answer named three rivals and not you, which is the number that actually moves a pipeline.

Two patterns in those 521 searches are worth knowing about, because they change what you should publish. The engines go to primary sources. 115 of the 521 searches used a site: operator to look a specific domain up directly. The hosts they looked up most were semrush.com (16 searches), tryprofound.com (15), support.google.com (10), openai.com (9), developers.google.com and profound.com (7 each) and ahrefs.com (6). Roughly half of those lookups are vendors' own sites and the rest are platform documentation. When an assistant wants a fact about a product or a platform, it goes to the owner of that fact. They ask for the official version, and they ask for a recent one. Across those searches the word the engines added most often after the obvious category terms was "official" — on 92 of them. A year token appeared on 73. The practical reading is that a dated, first-party page stating your own facts plainly is not a nice-to-have; it is the artefact the retrieval step is looking for. There is one number we will not give you, because it does not exist: how often a human actually types any of these prompts. Nobody has that ground truth for AI assistants, and any tool that quotes you an "AI search volume" is modelling it. Treat those figures the way you would treat an invented statistic.

Read the Generative AI performance report. It is free, it is first-party, and it is the only place you will see your own impressions in AI Overviews and AI Mode. Note the caveats above before you draw a conclusion from a small number. Identify AI referrals in GA4, which is easier than it used to be. AI Assistant is now one of GA4's default channels, described by Google as the channel by which users arrive from sources like ChatGPT, Gemini, Deepseek, Copilot or Grok. There is no tag to add and no custom channel group to build. Read the definition closely, though: it excludes Google's AI Overviews and AI Mode, which is precisely what the Generative AI report covers. The two sit beside each other rather than on top of each other, and neither double-counts the other. To see which assistant is actually sending people, switch the table's dimension from the channel group to Session source. Update, 5 October 2026: a filter on assistant hosts no longer catches all of it. GA4 takes a link's utm_source over its referrer, and assistants have started tagging their links: Gemini has been seen tagging links utm_source=gemini (Plausible, September 2026), and links ChatGPT cites have been seen tagged utm_source=openai. GA4 files those visits under the tag, and without a utm_medium they usually land in Unassigned rather than in the AI Assistant channel. Add the tag values to your session-source filter, alongside the sessions whose medium is ai-assistant. Read your server logs for AI crawlers. Whether a crawler fetched a page is a different fact from whether an answer cited it. Access is not citation, and conflating the two will flatter you. Then, and only then, check the answers themselves. Ask the assistants your buyers' questions and read what comes back. Do it more than once: the same prompt does not return the same answer twice, which is why a single check is closer to an anecdote than a measurement. The first three are free and take an afternoon. Most sites have never done them, which makes the fourth step easier to justify once you get there.

A tool is worth paying for when the thing you need is repetition and comparison, because those are what a person cannot do by hand. Running the same prompts across several engines on a schedule, keeping the sample size visible so a rate means something, and tracking the competitor set alongside your own brand is tedious, and tedium is what software is for. We build one, so read that as an interested party rather than a neutral one. A tool cannot give you prompt volume, and should not pretend to. It cannot tell you why an engine chose a source. And it will not fix the underlying problem if the answer is that the pages the engines read do not mention you — that is a publishing and a distribution problem, and the measurement only tells you where to point it. The honest sequence is: read your own free data first, decide whether the gap is real, and buy measurement when the manual version stops scaling.
