AI Search & AEO Statistics (2026)
Sourced, dated statistics on AI search adoption, referral traffic, market size, and AI citations — each figure traced to a primary source. Updated for 2026.
How big is the AI search market?
AI search is projected to become a major share of the overall search economy within a few years. The clearest forecast comes from McKinsey, which expects hundreds of billions in US spending to flow through AI-powered search by 2028, while Gartner expects a measurable decline in traditional search volume over the same period.
How many people use AI answer engines?
Usage of the major [answer engines](/glossary/answer-engine/) has scaled into the hundreds of millions of users and billions of daily interactions. The figures below are the most recent disclosed by each platform; where a company has not released a newer number, the figure is labeled with the date it applies to.
How fast is AI referral traffic growing?
AI referral traffic is growing at triple-digit annual rates and, more recently, converting better than other channels. Adobe Analytics tracks this across more than a trillion visits to US retail sites, making it the most-cited primary source for AI commerce traffic.
How does AI search shape buying decisions?
AI search has become an influential channel in how buyers evaluate products and which results they trust. Two 2025–2026 studies quantify this: one on B2B software buyers, one on general consumer trust.
How volatile and concentrated are AI citations?
AI visibility is unstable and heavily shaped by sources outside your own site. Brands frequently appear in one answer and vanish in the next, and a large share of [citations](/glossary/citation/) point to third-party pages rather than the brand's own domain — though estimates of the exact share vary.
Estimates vary widely and at least one analysis reaches the opposite conclusion, so treat the direction — that off-site sources matter a great deal — as the takeaway, not the precise figure.
How were these statistics verified?
Every statistic on this page was traced to its primary source — the originating report, study, or company disclosure — and dated, per our sourcing policy. We do not publish a figure sourced only to a blog that cites another blog. Where a seed figure could not be confirmed, it was replaced with current primary data or left off this page.
A few notes on method and freshness. Platform usage figures reflect the most recent number each company has disclosed, labeled with the date it applies to, because these change quickly. Traffic and conversion figures come from Adobe Analytics' periodic AI traffic reporting. The share of citations from third-party sources is shown as a range because credible analyses disagree, and we surface that disagreement rather than pick a single number. This page carries the year in its title and is refreshed in place as new primary data is published; the full verification log lives in our research notes.
