On November 8, 2026 we ran 1,040 buyer questions through ChatGPT, Claude and Gemini for 34 established local service businesses: plumbers, HVAC companies, electricians, landscapers and contractors in Boise, Reno, Spokane, Fort Collins, Salem, Billings and Eugene.
The assistants named the business we were checking in 10 of 1,040 answers, under 1%. Every one of those 10 came from ChatGPT, and they covered only 2 of the 34 businesses.
These are real companies with reviews, phone numbers and working websites. The assistants weren’t refusing to answer: 92% of answers recommended at least one local business by name, about six on average. They just recommended somebody else.
Roughly 30 questions per business across three assistants: ChatGPT 350, Claude 345, Gemini 345.
All from ChatGPT; one business accounted for 9 of them. Claude and Gemini named none of the 34.
956 of the 1,040 answers recommended at least one local business by name (about 6 per answer).
In each market and trade, the single most-recommended company appeared in 30–60% of answers; in 7 of 16 groups, one company was in at least half.
| Trade | Businesses | Answers | Named the business |
|---|---|---|---|
| Plumbing | 14 | 432 | 10 |
| HVAC | 11 | 334 | 0 |
| Landscaping | 4 | 124 | 0 |
| Electrical | 3 | 90 | 0 |
| Contracting | 2 | 60 | 0 |
The questions were the ones a homeowner types or says: “plumber Boise”, “furnace repair Spokane”, “best electrician sparks”, “drain cleaning Reno”, “emergency plumber”. Each business got about 11 queries built from its own services and towns, asked of each assistant.
In every one of the 16 market-and-trade groups we sampled, a short list of the same three to five companies came up again and again. That shortlist is the new first page of Google, except there is no page two.
Update, November 11, 2026. We kept asking ChatGPT the same questions each day for the businesses we track, and read every answer that did name one of them with a website. Across November 8–11 that was 90 links for 14 businesses.
At least 12 of the 90 links pointed to a web address that does not exist. The assistant built a plausible address from the company name (the name plus “heating”, or the name plus the city) and presented it as the company’s site. For one landscaper, all 6 mentions carried an invented address. Two more links went to a different company with the same name in another state.
So a buyer can be told to call you and still land on an error page or on someone else. The quick fix is to register the addresses the assistant keeps inventing and point them at your site. The lasting fix is making your real address the one every listing, profile and page agrees on.
Small sample, one assistant, four days; “does not exist” means the address had no DNS record when we checked on November 11.
This study measured who gets named, not why. These are the fixes we make for clients, based on how these assistants describe and cite local businesses.
Open ChatGPT, Claude or Gemini and ask “best [your trade] in [your city]”. Then ask it two more ways: a cost question and an emergency question. If your name doesn’t come back, a buyer asking the same thing isn’t hearing it either.
We write up the full version for local service businesses: every question, what each assistant answered, who it named instead, and the page changes that would put you in the answer. Ask for yours, or read how AI search optimization works.
