How much of your Google traffic comes from AI Overviews?
One site's test put AI Overviews and AI Mode at an estimated 21% of its Google clicks. Here is what you can measure and what to check this week.
On November 9, 2026, Search Engine Journal reported that Google's AI features sent one site an estimated 21% of its search clicks.
One site's estimate: 21% of Google clicks came from AI features
A consultant took one site out of Google's AI features for 28 days. He then compared its clicks with the next 28 days, after the site opted back in. He used the same searches and the same positions in each period. His estimate is that AI Overviews and AI Mode produced 21% of search clicks. Add a small lift on regular listings, which he attributes to AI visibility, and he puts the total at 23%.
About 10% of that site's Google impressions came from AI features. Those impressions turned into clicks at a higher rate. The click-through rate in AI features was about 0.9%, against about 0.4% across all of Google Search. He considers 0.7% to 1.1% a reasonable range.
He describes it as a single experiment on a single site. He says readers should treat the results "more as a directional yardstick than Google gospel." He also says not to assume the numbers apply to other sites. So use this as a reason to check your own numbers.
What Google's help pages say about AI features
Google says there are no additional requirements to appear in AI Overviews or AI Mode, and no special schema.org structured data to add (AI features help page, 2025-12-10). Its optimization guide says structured data is not required for generative AI search, and there is no requirement to break content into tiny pieces for AI (optimization guide, 2026-07-10).
Sites in AI features count toward your overall search traffic in the Performance report. Google added a separate view of impressions from generative AI features on June 3, 2026 (Search Central Blog, 2026-06-03). That report holds impressions only. Put simply, impressions show how often your pages appeared in AI features, and clicks show what people did next. Google's reports separate the first and not the second.
Google's published pages do not give a click count for AI features. Search Engine Journal reports that Google counts clicks on AI links as standard clicks, and that neither help page lists a way to separate them.
The Search generative AI control in Search Console is set to include by default. Google says it reached all websites worldwide as of August 31, 2026, and that it is not used as a ranking or inclusion signal for other parts of Search (control help page, 2026-08-31).
What to do this week
- In Search Console, open the Performance report and find the generative AI view. Write down the impressions from AI Overviews and AI Mode for the last 28 days, next to your total impressions for the same period.
- Leave the Search generative AI control on include, unless you have decided to opt out using your own numbers. Opting out removes your site from those features. In the consultant's test, the site dropped out in under an hour, and its AI impressions came back nearly as fast after it opted back in.
- Do not add llms.txt files or special markup meant for AI. Google says they are not needed.
- Keep each answer whole on the page. Do not split one answer into tiny sections for AI.
- Set up a before and after check. Compare clicks over two 28-day periods, with the same searches and positions in each, the way the consultant did. Record the result every month.
The trap: opting out and expecting the visits to stay
The trap has two parts. The first is excluding your site from the AI control while expecting to keep AI impressions. An excluded site loses those features, so those impressions go with them. The second is paying for llms.txt files, special markup or chopped-up answers because someone says they help with AI. Google's guidance says none of that is required.
