"Who's a good plumber near me?" is one of the most common local questions people ask, and more of them now ask it to ChatGPT. The answer is a short list of names, often with a line about why each was picked. For a plumbing business, that's either free word of mouth or a missed call you'll never know about. Most plumbers are missing out right now: in our November 2026 scan of 100 Dallas-area roofers, HVAC companies and plumbers, ChatGPT didn't name 96 of them in any of its answers.
Plumbing is also the trade with the most research behind it, so we can be more specific here than for most trades. Still, no study shows that any single step causes ChatGPT to recommend a business. What follows is what the evidence points to, plus the work that helps your regular Google visibility at the same time.
Where ChatGPT gets its information about plumbers
ChatGPT answers local questions by searching the web and summarizing what it reads. You can see what it reads on our public pages. Look at who ChatGPT recommends for plumbers in Dallas or plumbers in Houston and scroll to "Websites AI read to decide."
Three findings from outside studies line up with what we see:
- Directories are a main source. In a study of about 14,000 plumber-style questions (Relentless Digital, reported by Roundhouse in August 2026), the most-cited sites included Angi, BBB, Thumbtack, HomeAdvisor, Yellow Pages and Expertise.com. Yellow Pages showed up only in ChatGPT's answers. The study's full method wasn't published, and the agency behind it sells plumber marketing, so treat the exact counts loosely.
- ChatGPT barely cites Google. In a separate 34,742-answer home-services study (Cheers, September 2026), ChatGPT cited Expertise.com in about 32% of answers, Angi/HomeAdvisor in about 29%, BBB in about 15%, and Google in 0.1%.
- License boards get read. On our Dallas plumber page, the Texas State Board of Plumbing Examiners site (tsbpe.texas.gov) was one of the sources ChatGPT used when we checked in November 2026.
The plumber's checklist
Your website
- ChatGPT isn't blocked. OpenAI says sites that block its OAI-SearchBot crawler won't appear in ChatGPT search answers. Ask your web person to check
robots.txt. Changes take about a day. - Your license number is visible on every page footer and your About page. In Texas, that's your TSBPE license.
- One page per service: drain cleaning, water heaters (tank and tankless), leak detection, slab leaks, sewer line repair, repiping, emergency plumbing.
- Your service area is named: the cities and neighborhoods you cover, in plain text.
- An FAQ with straight answers: Do you charge a trip fee? Are you available 24/7, and what does after-hours cost? How fast can you get here? Do you offer upfront pricing? What warranty do you give on parts and labor?
Listings (same name, address and phone everywhere)
- BBB business profile (free to claim; accreditation is a separate paid program)
- Angi / HomeAdvisor pro profile (one signup; paid leads are optional)
- Thumbtack (free to join; you pay only for leads you choose)
- Yellow Pages
- Yelp. The studies disagree on whether ChatGPT reads Yelp right now. Perplexity clearly does, and it's free.
- Nextdoor, Facebook, Bing Places, Apple Business Connect
- Google Business Profile, complete and accurate (essential for Google's own AI answers)
- Expertise.com. You can't apply. They choose businesses using public data, license checks and a mystery-shop phone call, so a well-answered phone matters.
- PHCC or other trade association membership, if it makes sense for you
Reviews
- Ask every customer for a Google review by text, right after the job.
- Aim for new reviews every week, not a burst once a year.
- Reply to reviews with specifics.
- Never buy reviews, write your own, or ask only the happy customers.
Why the push on freshness: a November 2026 study by Revfer (about 2,900 AI answers in 40 cities) found ChatGPT named about 1 in 5 businesses whose newest review was under a week old, and fewer than 1 in 50 when the newest was a year old. It's observational, since busy plumbers get more reviews and more mentions, but it matches how customers read reviews. In BrightLocal's 2026 consumer survey, 74% said they only look at reviews from the last three months.
Things that sound useful but don't do much
- Schema markup. Fine to have, but an Ahrefs test across 1,885 pages found no significant change in ChatGPT citations.
- Keyword-stuffed business names. "Best 24 Hour Plumber Dallas" as your Google profile name breaks Google's rules and risks suspension.
- Lots of Google posts and photos to win ChatGPT. They help on Google. The data suggests they matter little for ChatGPT once review count and freshness are accounted for.
A word on fake listings
Plumbing, like garage doors and locksmiths, is full of lead-generation listings with made-up names, no real address, and "open 24 hours." They make it harder for any system to tell real businesses apart. The best defense is boring: a real address or a clearly marked service area, a consistent phone number, your license number everywhere, and real reviews that mention real jobs.
Keep AI in perspective
AI is one more place people look, and still a small one for most plumbers. A 2026 SOCi study of 350,000+ locations found ChatGPT recommended only about 1.2% of them. The work above is worth doing because it also helps every customer who checks you on Google, Angi or BBB before calling.
FAQ
Does ChatGPT know if I'm licensed? It can read license-board websites and your own site, so make your license number easy to find in both places.
Should I pay for Angi or Thumbtack leads to get recommended? You don't need to buy leads to have a profile. Paid leads are a separate decision based on your cost per job. A complete, accurate profile is the part that matters here.
How often should I check? Monthly. Ask the same few questions several times each, since answers vary from run to run.
