The short version
- In a 540-search study, AI Overviews showed on 15% of local searches like "plumbers in Houston." The Map Pack showed on 93%.
- AI answers show up on most how-to and cost questions, and fewer people click through when they do.
- Google says there are no special requirements or tricks to appear in AI Overviews or AI Mode.
- What helps: a complete Google profile, consistent business info, clear service pages with price ranges, and steady reviews.
- llms.txt files and "AI SEO" add-on packages are mostly hype for a local plumbing company.
Some homeowners do use ChatGPT and Google’s AI answers to find help, and that number is growing. But when someone needs a plumber now, the Map Pack still owns the screen. AI answers mostly show up on how-to and “how much does it cost” searches. So the play for a plumbing company isn’t an “AI SEO” package. It’s doing the local basics well enough that both Google and the AI tools trust what they read about you.
Here’s what the data actually says, with dates, so you can make your own call.
Where AI answers show up (and where they don’t)
The most useful study for plumbers comes from Whitespark. In May 2025, they checked 540 searches by hand across Houston, Phoenix and Denver, in six industries including plumbing.
| Type of search | Example | AI Overview showed |
|---|---|---|
| Local intent | “plumbers in Houston” | 15% |
| Informational | “why is my water heater making noise” | 92% |
| Hybrid cost + place | “water heater replacement cost in Phoenix” | 97% |
On those local-intent searches, the Map Pack showed up 93% of the time.
Ahrefs saw the same pattern at a much bigger scale. Its November 2025 analysis found AI Overviews on just 7.9% of local searches, but on 57.9% of question searches.
The takeaway: when a pipe bursts, people search for a plumber and call from the Map Pack. When they’re researching, Google answers them directly.
AI answers cut clicks on research content
When an AI summary does appear, fewer people click. Pew Research Center tracked real browsing in 2025. People clicked a traditional search result on 8% of visits that showed an AI summary, versus 15% when there wasn’t one. They clicked a link inside the summary only about 1% of the time.
For a plumber, that means:
- Blog posts that answer general questions will bring fewer visits than they used to.
- Your service pages and your Google Business Profile matter more, because that’s where the ready-to-hire people still land.
- Judge your content by calls and booked jobs, not by traffic.
How many people use ChatGPT for local help?
More than you’d think. BrightLocal’s 2026 consumer survey (1,002 U.S. adults, published February 2026) found 45% had used ChatGPT or other AI tools to get local business recommendations, up from 6% the year before.
That’s a huge one-year jump in a single survey, so read it as a direction, not a precise number. The same survey shows Google is still the main place people look up local businesses.
Google’s AI is already calling plumbers
Here’s something most plumbers haven’t noticed yet: Google’s AI can call businesses to ask about prices for a searcher. Invoca tracked these calls and reported in December 2025 that they rose 324% from October to November across the industries it studied. Plumbing averaged more than 650% monthly growth.
They were still under 1% of all calls. But plumbers answered only 66% of them, and across all industries, 48% of the answered calls never got a price.
If you want to win these, have a price-range answer ready for your common jobs, and put typical ranges on your website so the AI can read them.
What actually helps you show up
Google’s own documentation says there are no additional requirements and no special optimizations needed to appear in AI Overviews or AI Mode. The same things that make you a strong local business make you a strong AI answer:
- A complete Google Business Profile. Right primary category, every service, real hours, real photos. See our Google Business Profile setup guide.
- The same details everywhere. Name, phone, address, service area and hours should match on your profile, your website and directories.
- Service pages that answer real questions. What it costs (as a range), how long it takes, what affects the price, whether you do emergencies. That’s exactly what AI summaries pull from.
- Steady, honest reviews. AI answers lean on what customers say about you.
- Mentions on sites people trust. Local news, associations, “best plumbers in [city]” roundups and your suppliers’ websites. Earn them; never fake them.
What’s mostly hype
- “AI SEO” add-on packages. Some agencies charge extra for it. For a local plumbing company, it’s mostly the same work as good local SEO with a new label.
- llms.txt files. Google says Search ignores them, and an SE Ranking study of about 300,000 domains found no link between having one and getting cited by AI. Adding one won’t hurt, but it won’t help with Google either.
- Rewriting pages “for AI.” Google says there’s no special formatting or chunking required. Adding real information helps. Rewording doesn’t.
How to tell if AI search is sending you work
Don’t guess. Check:
- Ask callers how they found you. “Google” now might mean the Map Pack, an AI answer or a search ad. Ask which.
- Look at Google Search Console. It shows how often your pages appear in Google Search, including AI features.
- Watch your referral traffic. In Google Analytics, look for visits from chatgpt.com, perplexity.ai, copilot.microsoft.com and gemini.google.com.
- Test it yourself. Once a month, ask ChatGPT and Google something like “best plumber for a water heater replacement in [your town]” and note who shows up.
The bottom line
AI search is real, it’s growing, and it’s changing how research content gets traffic. It hasn’t changed how emergencies get booked. Win the Map Pack, build service pages that rank, keep your details consistent, and make your website answer the questions homeowners actually ask.
If you want to see how you show up today, in Google Maps and in AI answers, our free market check covers both.
