AI search statistics, each linked to its source
Pages on ChatGPT usage, LLM market share, SEO in the AI era and generative engine optimization. Every figure points back to where it came from.
How we source
Every figure, with its source
Each page collects the figures people quote about AI search, from ChatGPT usage to AI Overviews and referral traffic. Every number links to the study or company that published it, with its date.
Next to the public figures we add LLMReach's own measurement of 750 AI answers across 25 sectors. For the method behind it, see our research.
Primary sources only
Figures come from the company or study that measured them, never from a roundup.
Dated
AI search changes fast, so every figure carries the date it was published.
Our own data
Where public data is thin, we add what we measured. See where AI gets its information.
