Plumbers: AI Skipped 73% of the Top Maps Plumbers in 11 Cities

A pipe bursts at night. The homeowner grabs a phone and asks ChatGPT or Gemini who to call. The answer names a few plumbers. If your name is not one of them, that call may go to someone else. That can mean a lost call. It can mean a lost job.

We checked if these tools name the plumbers on Google Maps. Those plumbers sit at the top of the map. This is a local SEO for plumbers question. It is about who gets the call.

In our Oct 2026 test of 12 AI answers per city and trade, AI skipped 73% of the top plumbers on Google Maps.

What we tested

We looked at 11 big US cities. In each city we saved the Google Maps top 10 plumbing companies. That is 110 companies.

We sent 6 questions to ChatGPT in each city. We sent 6 questions to Gemini in each city. That is 12 answers per city. The test ran on Oct 21, 2026.

Skipped means one thing. The company was in the Maps top 10. None of the 12 answers said its name.

We used the same check in every city. We did not pick favorite companies. This page does not name any company.

The results

Here is the main count again. 73% were never named. In our Oct 2026 test of 12 AI answers per city and trade, most of the top plumbers on Google Maps were left out.

ChatGPT alone skipped 80%. Gemini alone skipped 81%. The two tools were close. Neither one named most of the top plumbers.

A top spot on the map did not protect a company. The number 1 plumber on Google Maps was skipped in 7 of 11 cities. That is 64%. The plumber at the top of the map was still easy to miss.

Strong plumbers were skipped too. Strong means 4.5 stars or better and 100 or more reviews. 52% of them were skipped. That group has 58 companies. Good stars and a long review list were not enough to get named.

A high Maps rank is not the same as a name in the answer. A person who asks ChatGPT or Gemini may never hear that name. They may call a plumber who was named instead.

Plumbing tied with injury law at 73%. Only HVAC was higher, at 75%. All 8 trades we tested came to 70% combined. You can read about HVAC in AI skipped 3 in 4 top HVAC companies on Google Maps.

You can read the full test in 7 in 10 top Google Maps businesses are never named by ChatGPT or Gemini.

City by city

Each city here is the Maps top 10 for plumbing. The bars and the table use the same numbers. They show the share that was skipped. These numbers are from the same Oct 2026 test of 12 AI answers per city and trade.

Phoenix, AZ was the highest, at 100%. Every top plumber there was skipped. Los Angeles, CA was next, at 90%.

Seattle, WA and Chicago, IL were 80%. San Diego, CA, Houston, TX, Denver, CO, Dallas, TX, and Atlanta, GA were 70%.

Fort Worth, TX was 60%. Baltimore, MD was the lowest, at 40%. It was the only city where fewer than half of the top plumbers were skipped.

A good map spot was not enough in most places we checked.

Local SEO for plumbers: steps you can take

You want more calls. You want more jobs. A Maps rank alone did not bring the AI name in this test. Local SEO for plumbers is still plain work you control.

No one can force ChatGPT or Gemini to name your company. No one can promise you will be first. No one can promise the phone will ring. The steps below may help. They are not a promise.

Keep your Google Business Profile complete and active. Add your hours. Add your phone. Add your services, like drain cleaning or water heaters. Add photos of real jobs.

Ask every happy customer for a review. Ask soon after the job, while the fix is fresh. Do not buy reviews. Do not write fake ones.

Use the same name, address, and phone everywhere online. Check your website, your Google page, and every listing you are on.

Have a clear page on your site for each service you offer. Have a clear page for each city or area you cover. Say what you do in plain words. Say where you do it.

Get listed on well-known sites people trust. A trade group, a local news list, or a big directory can be a start. Use the same name and the same phone on each one.

Then check your own company. One answer is not enough. Ask ChatGPT and Gemini more than once. Count how often your name shows up. Our guide on how to check your AI visibility shows a simple way to do it.

How sure are we

Names were matched automatically, and some get missed. So the true number could be lower than 73%.

This was one day. It was one run. AI answers change a lot from day to day. Ask again later and the names can change.

Only 10 companies were checked in each city. One city's number can swing 10 to 20 points. The total of 110 companies is steadier. Trust the wide count more than one city.

Questions were asked from a US-wide setting. The city and the state were in the question. We did not stand inside each city and ask.

We do not turn this count into a rank. It is not a promise. Read how we check for the full method.
