AI search statistics measure how often AI-generated answers appear in search results, how they change click behavior, and how many people now start their research inside an AI tool rather than a search engine.

This page collects 11 statistics: 8 from our own research and 3 from Semrush, Reuters and Gartner. Every figure names its source, links the page that published it, and carries the date we last confirmed it. Anything here is free to quote with attribution: there is a suggested citation at the bottom.

Last updated November 6, 2026.

SEO risk self-check

Is your SEO still measured the old way?

Low exposure: 0 of 5 traditional habits

Your measurement has kept pace. Keep tracking how your brand appears across platforms and AI surfaces, not just rankings.

Traditional SEO is still the foundation of visibility. The risk appears when the measurement around it stays static. Google also says optimizing for its AI features is “still SEO”.

Click to expand

What happens to clicks when AI answers the question

Methodology and sourcing

Figures attributed to Indexed come from our own SERP measurements; each links to the methodology section of the study that produced it, where the sample, date range and limitations are stated in full. Third-party figures link to the page that published them rather than to an article repeating it, wherever we have been able to find it, and where we have not, the statistic says so rather than hiding it.

"Last verified" means a person opened that source and confirmed it still states this figure on that date. It is not the date this page was last edited. Any statistic older than 12 months is flagged for re-checking by a scheduled job. Statistics in this field have a short shelf life, and we would rather show you the date than imply a freshness we cannot support.
