How these numbers were compiled
This page aggregates publicly reported research from the SEO industry's most active data publishers across 2024–2026: Ahrefs, Semrush, BrightEdge, seoClarity, Similarweb, SparkToro, Schema App, Moz, the Reuters Institute, Press Gazette, and Gartner — plus primary statements from OpenAI and Google.
Where multiple sources report conflicting figures, we've either triangulated (and said so in the citation) or cited the source with the most transparent methodology. Where a number is directional rather than precise — ChatGPT's WAU, for example, which OpenAI reports in public appearances — we've flagged the range rather than a single point estimate.
Feel free to cite any stat on this page. The original source is named on every card so you can verify independently.
