Version 2 asks 24 questions three times each on ChatGPT, Claude, Gemini and Perplexity (288 answers) and adds Google AI Overviews. Every rate comes with its count and a 95% interval.

Angi, named in 102 of 288 four-engine answers (35.4%, CI 30.1–41.1%). Yelp was second at 96 of 288 (33.3%). The intervals overlap, so the two cannot be separated statistically.

How often do Google AI Overviews appear for these questions?

An overview appeared on 53 of 63 searches (84.1%, CI 73.2–91.1%). Within those 53 overviews, Yelp was named most often, in 21 (39.6%).

How this study was measured

24 questions × 3 runs each × 4 AI engines = 288 answers + 63 Google searches · 53 AI Overviews

24 questions asked three times on each of ChatGPT, Claude, Gemini and Perplexity, measured October 30 to 31, 2026. United States, English; Google retrieval uses desktop results. Models: gpt-5-mini, claude-sonnet-5-5, gemini-3.6-flash only, sonar-pro. Google AI Overviews come from DataForSEO, not inferred chat answers. Appearance counts returned text, including ungrounded answers; citation rates use grounded answers. Longer overlapping names suppress shorter ones; First mention is the earliest eligible name order. Own-domain rates include declared domains and subdomains; shared parent scopes may count for multiple names and cannot be summed as unique citations.

Own-domain citations count a domain plus all its subdomains, with the same rule in every table.

Definitions

  • Appearance rate: answers naming the tracked name ÷ answers returned, with Wilson 95% intervals.
  • First mention: average order in which the tracked name first appears (1 = first).
  • Own-domain citation: grounded answers citing the tracked name's domains ÷ grounded answers.
  • Citation share: citations to the tracked name's domains ÷ all citations.

Limits

  • Only 40 tracked providers are ranked; results are not an exhaustive market ranking.
  • Only the tracked brands were scored. Untracked names that appeared often were not scored, including GoHealth Urgent Care (18 answers), Houzz (17 answers), NextCare Urgent Care (16 answers), WellNow Urgent Care (15 answers), California Contractors State License Board (15 answers).
  • Answers were collected over two days, October 30 and 31, 2026. 351 of 360 planned results were returned. 9 AI Overview lookups were excluded after at most three total attempts.
  • 63 successful Google searches: 53 overviews shown; 10 without an overview. Failures are excluded, not scored as zero.
  • 25 chat answers had no search sources and are left out of the citation figures.
  • Removing 2 Core questions naming tracked subjects leaves 264 eligible answers. The top two are Angi (88/264) and BBB (85/264); their order changes.
  • Names with no tracked own site are shown as None. Source types use Company / brand sites only for verified official organisations; other unresolved sites are Other / unclassified.
  • Wilson 95% intervals are descriptive; overlapping leading intervals do not establish a sole leader. Measurements do not endorse medical, legal, financial or product claims.
  • The tracked names are the national chains, franchise networks and finder platforms from the original report, plus a few added directories. Two Core questions name tracked platforms (Yelp and Google reviews; Angi and Thumbtack). Independent local businesses are not tracked one by one.
  • Answers came from each engine's API (model IDs above); the consumer apps can answer differently.
