Who ChatGPT recommends (October 2026)

1,199 ChatGPT answers, 20 niches, 10 US cities, every question asked twice.

Which local businesses does ChatGPT name when a customer asks for a recommendation? 20 niches, 10 US cities, 3 questions each, every question asked twice on chatgpt.com with web search on. Published by OperStack.

Dataset structure

  • mentions: one row per business named in an answer (7,065 rows).
  • answers: one row per answer (1,200 rows).
  • summary: one row per niche and city (200 rows).

Field descriptions, the exact questions and the parsing rules are in DOCUMENTATION.md.

Key findings

  • Answers change between runs. Asked the same questions a second time, ChatGPT named again 67% of the businesses it had named the first time (1,570 of 2,344).
  • Wording matters. "What are the best..." and "Which ... has the best reviews?" asked in the same city produced a different first-named business in 300 of 399 cases.
  • A local map comes first. 1,181 of 1,199 answers opened with a map of local businesses.
  • Yelp is rarely a cited source. yelp.com appeared among the cited sources of 3 of 1,199 answers.
  • Many names appear once. 47% of the businesses named in a city appeared in only one of the 6 answers about that city and niche (1,481 of 3,175).

Collection

ChatGPT (chatgpt.com, web search on, country US, no logged in user), questions sent through an automated browser (Bright Data ChatGPT Scraper) on 3 October 2026. Parsed with rules, no language model. Hand check of 40 answers: about 99% of extracted names correct (3 of about 242 wrong), 33 of 40 answers (82.5%) parsed without errors. Full answer texts are not included.

Limitations

Names mentioned in plain text without formatting are sometimes missed. One day snapshot; answers vary between runs. Not a quality ranking of businesses.
