AEO guide 09
Use Google Analytics 4's built-in AI Assistant channel for visits from chatbots, and add a custom channel only for sources it misses. Read Search Console and Bing Webmaster Tools for AI impressions and citations, ask new customers how they found you, and report these together each month without treating any one number as the full picture.

Why this matters
When an AI assistant recommends your business, the customer may click a link, call the number shown, or search your name later. Only the first shows up as a visit your analytics can label, and even that is sometimes recorded as direct traffic. Clicks from Google's AI Overviews and AI Mode are counted with ordinary Google search visits, so they can't be separated in analytics at all.
That makes AI search easy to overstate or ignore. The tools have improved: Google Analytics 4 (GA4) added an AI Assistant channel in May 2026, Search Console now reports AI Overview and AI Mode impressions, and Bing Webmaster Tools shows how often Copilot cites your pages. Used together with a simple question to new customers, they give a fair picture without paying for a score nobody can verify.
Responsible practices
In May 2026, Google added an "AI Assistant" channel to GA4's default channel group for visits from sources such as ChatGPT, Gemini, Deepseek, Copilot, and Grok. It does not include Google's AI Overviews or AI Mode, which stay in Organic Search. Open Reports, then Acquisition, and look for AI Assistant in the channel list before building anything custom.
Google's help page for this channel does not list Perplexity, and other assistants may be missing. Check the Session source report; if an assistant shows up under Referral, create a custom channel group with an AI channel placed above Referral, because the first matching channel wins. Standard GA4 properties allow two custom channel groups, and they apply to past data too.
GA4 matches the whole source value, so a loose pattern can catch unrelated sites. This pattern was tested to match the main assistant domains and not match Google, Bing, Gmail, or Facebook: ^(.*\.)?(chatgpt\.com|openai\.com|perplexity\.ai|claude\.ai|copilot\.microsoft\.com|gemini\.google\.com|bard\.google\.com|deepseek\.com|grok\.com|meta\.ai|mistral\.ai|you\.com|phind\.com|poe\.com|edgeservices\.bing\.com)$ Never add bing.com or google.com, which would swallow normal search traffic.
Search Console's Generative AI performance report, available for all sites since August 31, 2026, shows how often your pages appeared in AI Overviews and AI Mode. It shows impressions only, by page, country, device, and date, with no clicks or queries. Clicks from these features are still counted in the regular Performance report, so compare the two page by page as a rough guide.
Bing Webmaster Tools shows how often your pages are cited in Copilot, Bing's AI summaries, and some partner AI experiences, with sample "grounding" questions that led to the citation. Since June 2026 it also groups questions by intent, including Local, and shows your share of citations. Bing calls citation share an observational metric, not a ranking, and it includes no traffic data.
Add "AI assistant (ChatGPT, Gemini, etc.)" to your "How did you hear about us?" options on forms and at intake. It catches customers who saw you in an answer and then called or searched your name. Pair it with your monthly AI answer check, reported as "mentioned in X of Y runs", because single answers vary too much to track.
Worked example
Hypothetical example: a dental practice adds a short AI section to its monthly marketing report. Numbers are illustrative; the point is what each line measures and what it cannot show.
No single line tells the whole story, but together they show whether AI search is bringing real inquiries and which pages it relies on.
Measurement setup
Open GA4's traffic acquisition report and check whether the AI Assistant channel appears.
Look at Session source under Referral for assistant domains the AI channel missed.
Verify your site in Bing Webmaster Tools and open the AI Performance report.
Open Search Console's Generative AI performance report and note your top pages.
Add an "AI assistant" option to your "How did you hear about us?" question.
Set up a custom AI channel above Referral using the tested pattern, and show you the before-and-after numbers.
Add a short AI section to your monthly report covering GA4, Search Console, Bing, and intake answers.
Mark leads and bookings as key events in GA4 so AI visits can be judged by inquiries, not visits alone.
Avoid these mistakes
AI assistants decide what to show, change often, and can give different answers to different people, so mentions, citations, and recommendations are not guaranteed.
Questions business owners ask
Google's definition of the AI Assistant channel excludes AI Overviews and AI Mode. Those clicks are counted as Organic Search in GA4 and in the regular Search Console Performance report. The Generative AI report shows how often your pages appeared in those features, but not clicks.
Only if you see assistant traffic landing in Referral. Google's list covers the largest assistants but does not name every one, such as Perplexity. A custom group with the tested pattern above catches the rest, and it applies to past data as well.
No tool can see the questions real customers ask or how answers are personalized to them. Trackers send their own sample questions and report what comes back, which is useful as a trend at best. Google says no third-party tool has access to its internal ranking or AI systems.
Yes, if you track it simply. For most local businesses it is a small share of visits today, but those visitors often arrive ready to book, and much AI influence shows up as calls and direct searches instead. Watch inquiries and intake answers, not just sessions.
