Google Business Profiles of the plumbers AI names: what they have and what they lack (November 2026)

Data last verified: 8 November 2026. Figures re-checked against their primary sources under the Whito rolling re-verification programme.

Most advice on Google Business Profiles is a checklist. Fill in your hours. Add photos. Ask for reviews. None of it tells you what the businesses that actually get recommended have done.

So we counted. We took the plumbers that AI assistants named in our emergency plumbers monthly record and read each one’s public Google Maps listing. This page reports what we found, in counts. It does not name any business.

The study in five numbers

• 25 of 28. We found a Google Maps listing for 25 of the 28 plumbers the AI assistants named. Three names did not bring up a listing at all.
• 25 of 25. Every listing we found showed a phone number and opening hours. The basics were not the difference.
• 3 of 10 against 15 of 15. In Carmarthen, 3 of the 10 listings linked to the firm’s own website. In London, all 15 did.
• 5 of 12. Only 5 of the 12 plumbers named for Carmarthen had a listing with a Carmarthen address. Two listings were pinned more than 100 miles away, in England.
• 18 of 25. 18 listings said they were open 24 hours, every day. 7 did not, although every question asked for an emergency plumber.

What we counted

For each listing we recorded what anyone can see on Google Maps without logging in. No data came from the businesses or from a paid tool.

The website link is where the towns split

Every London listing linked to the firm’s own website. In Carmarthen, the link went somewhere else on 7 of the 10 listings.

This does not mean a website is what got these firms named. AI assistants still named seven Carmarthen plumbers whose listing did not link to their own site. In a small town there are fewer firms to choose from. What it does show is that in a big, crowded city, every firm the assistants named had its own site behind its listing.

Named for a town, listed somewhere else

We asked about Carmarthen. Of the 12 plumbers named:

• 5 had a listing with a Carmarthen address.
• 1 had an address elsewhere in Carmarthenshire.
• 2 showed no address, with the map pin elsewhere in west Wales. That is normal for a firm that works from home and visits customers.
• 2 showed no address, with the map pin more than 100 miles away in England.
• 2 brought up no listing under the name the AI used.

For London, 15 of 16 names had a listing. 11 showed a London street address and 4 showed none. One firm had two separate listings under the same name, both linking to the same website.

Reviews: more in London, all marked unverified

• The middle London listing had 170 reviews. The middle Carmarthen listing had about 37.
• 14 of the 25 listings had a perfect 5.0 rating. 2 were below 4.5.
• 12 of the 25 had fewer than 50 reviews. AI assistants still named them.
• Every one of the 25 listings carried Google’s own note: “Reviews aren’t verified”.

A high star rating is common among the firms AI names, so it tells you little on its own. Read a few recent reviews, and check the firm itself. Our four checks before you pay a plumber take about five minutes.

What this means if you run a plumbing business

Your profile basics are not a competitive edge. Every firm the assistants named had them. They are the entry ticket. Fix them in this order, and stop at the first gap.

1. Start: make the basics true. Phone number, real opening hours, the right category. If you do not answer at 3am, do not say 24 hours. A missed emergency call costs you the job and a bad review.
2. Start: point the website link at your own site. A Facebook page or a directory profile sends the customer somewhere you do not control. A one-page site with your phone number, your area and a price is enough.
3. Build: add your own photos and reply to reviews. 22 of the 25 listings had owner photos. 15 had an owner reply near the top of their reviews. Both take minutes a week.
4. Scale: only then think about booking buttons and extras. 8 of 25 had a “Book online” button. That is a later step, not a first one.

How we did it

• The names. The 28 different plumbers named by Google AI Mode and ChatGPT on 4 November 2026, across 16 questions about London and Carmarthen. These are the answers recorded in edition 1 of our emergency plumbers monthly record. Spelling variants of one firm were counted once.
• The search. On 8 November 2026 we searched Google Maps for each name with its town. Where that failed, we tried up to two more searches using details from the AI answer, such as the street. A listing counted only if its name, website or phone matched the firm the AI named.
• The fields. We read the public listing page, not any business account. “Owner replies” covers only the three reviews Maps shows first, not every review. “Photos by owner” means Maps showed a “By owner” photo filter.
• One firm, two listings. Counted once, using the listing with more reviews. Both listings had the same fields.
• No names. This page reports counts only. The firm-level file stays with Whito.

Limits

• 28 names in two towns. This is a snapshot of who AI named, not of all plumbers.
• One reading on one day. Listings change, and Google changes which fields it shows. Every count above is dated 8 November 2026.
• We cannot see what Google AI Mode or ChatGPT read when they chose a firm. These counts describe the named firms’ listings. They do not prove that any field caused a firm to be named.
• Google may hide some fields, such as the business description, on some views. We report only what the public page showed us.
