Methodology
- Panel. Each category is a fixed panel of commercial keywords. We publish the panel size (keywords tracked) every month, so panel changes are visible; month-over-month comparisons should be read against it. Keyword lists themselves are not published.
- Cadence. One Google US search fetch per keyword per week. Weeks belong to the month of their Monday capture date.
- A sample, not a census. AI Overviews vary per query, per location, and per day. These tables report what our captures observed — never what Google “always” shows. We make positive-evidence claims only: a brand was cited N times in M fetched captures. We never claim a brand is absent from AI Overviews.
- Denominators. Some captures record that an AI Overview appeared without its content being retrievable. Those count toward the “showed an AI Overview” rate but are excluded from every citation denominator — citation counts are always “N of M fetched captures.”
- Citations. A citation is a domain appearing among an AI Overview's reference sources or in-answer product cards. Subdomain siblings are folded together (us.example.com counts as example.com).
- Exclusions. Brand-name searches are excluded — only category keywords feed this data. Domains belonging to Edgebrief customers are excluded from all published tables.
- Scope. Google AI Overviews only. This series makes no claims about ChatGPT, Perplexity, or other AI answer surfaces.
Edgebrief customers get this weekly — for their own keywords.
