AI used one plumber's website 8 times. It never said the name.

From our Austin trades data. Cited and named are different results, and the gap shows up in real answers.

The short answer

AI can cite your website as a source and still recommend a different company. In our Austin run on November 3, 2026, one plumbing company's site was listed as a source in all 8 asks of "What should I look for when hiring a plumber?" and the company was named in none of the 160 answers. The page answered a general question. The names came from ranking lists.

One Austin plumbing company's website was listed as a source in all 8 asks of a question about hiring a plumber. The company was never named once, in any of 160 answers.

This came out of our Austin trades study. We asked an AI search engine homeowner questions about plumbers, roofers, HVAC companies and electricians, and then checked two things separately for 40 companies: was the company named in the answer, and was its website cited as a source.

Those are different events. The data shows how far apart they can be.

What we saw

Perplexity, November 3, 2026, Austin, Texas. Method and limits are in the full study.

We ran the same questions again on November 5. This time 5 checked companies had a site cited. Three were cited and never named (the plumber, in 4 of 8 asks, plus a roofer and an HVAC company, 8 of 8 each). One was cited and named in 2 of 8. One was cited in 5 asks and named in all 5.

So the count of companies cited but not named was 1 of 40 on November 3 and 3 of 40 on November 5, plus a partial case each time. It is a minimum. We matched sites to companies by how the domain name resembles the company name, and could miss a company whose domain looks nothing like its name.

Why it happens

01

The page answered a general question

"What should I look for when hiring a plumber?" asks for a checklist. The answers gave one: verify the license, confirm insurance, get a written estimate, ask about warranty. None of the 32 "what to look for" answers across all four trades named a company.

A page that explains how to hire a plumber is useful to that answer. It supports the checklist. Nothing in the question asks the engine to pick a business, so it picks none.

02

The names came from other pages

When the question asked for a company ("who is the best plumber", "who are the most trusted"), the answers named companies. The sources listed for those questions were not company sites. By domain name, none of the ten sources behind "who is the best plumber" looks like a plumbing company's own site. They read like review sites, local news, and "best of" roundups. We did not open each one.

The plumber's site was never in that source list. Its advice was used on one question. Its name was nowhere on the questions that name businesses.

The short version: the engine used the plumber's page to explain, and used somebody else's list to recommend.

03

Cited and named are different jobs

A citation says "this page supported a sentence." A name says "this company is an option." An engine can do the first without the second. How AI engines decide what to cite covers the documented side.

What an owner can do about it

Cheap things to try. We have not tested that any of them changes who gets named.

01

Look at both lists, not one

Ask your three money questions eight times each. Write down who is named. Then open the sources the engine shows and note whether your site is among them. If you are cited and not named, the next two steps apply. If you are neither, start with the second.

02

Make the page say who you are and where you work, inside the answer

If a page is already being read, make the sentences that answer the question carry your name. "A licensed plumber in Austin, Texas, [company name], will..." beats a company name that only sits in the header and footer. Put the city, the service area, your license number and what you do in plain sentences near the top.

The limit: we did not test whether this gets a company named. It is the cheapest thing to try because the engine has already found the page. It cannot make an engine pick you over a company that appears on more lists.

03

Get onto the lists the names come from

The names in our "best" answers came from roundup and directory pages, not company sites. Local data points the same way. BrightLocal found Google Business Profile makes up "28.5% of all citations" in local AI answers, and that Yelp "appeared as a source in 80% of all answers from ChatGPT" (August 2026). Claim and complete your Google Business Profile and the review and directory pages your trade is listed on.

The limit: being listed does not guarantee a mention, and lists change. Check again in 30 days. See how long it takes to see results.

What this does not tell you

It is one company

The headline case is 1 company out of 40 on one day. It shows the pattern exists. It does not show how common it is across trades or cities.

"Cited" means listed as a source

It means the engine's source list for that answer included the site. We did not check which sentence each source supported. In 18 of 20 questions on November 3, the source list was identical across all 8 asks. So "8 of 8" is closer to one lookup seen eight times than eight independent ones. On November 5 the same plumber's site was cited in 4 of 8.

One engine, one metro

Perplexity only, Austin only. We did not measure ChatGPT, Gemini or Google's AI Overviews, and they may cite and name differently.

Nobody named

No company we checked is named here. The study page has the method.
