I Asked ChatGPT to Recommend a Plumber in Columbus. Here's What Happened.

Last Tuesday I sat down at my laptop, opened ChatGPT, and typed:

"I need a plumber in Columbus, OH for a slow kitchen drain. Who would you recommend?"

Here's what came back, more or less word for word:

Here are a few well-reviewed plumbers in Columbus, Ohio that could help with a slow kitchen drain:

1. Apex Plumbing & Drain — Highly rated for drain cleaning, with same-day service available. Located on the east side, serves most of Franklin County.
2. Eco Plumbers — Large local operation with strong reviews and 24/7 emergency service. Multiple service vans, often available same-day.
3. Drain Wizard Columbus — Drain specialists focused on residential clogs and sewer issues. Family-owned.

For a slow kitchen drain specifically, I'd start by calling Apex or Drain Wizard since drain work is their core service.

Three businesses recommended. Three phone numbers homeowners will call before the rest of the market gets a shot.

Notice what didn't happen

ChatGPT didn't show me a list of "top 10 plumbers in Columbus." It picked three. Three.

For most of the homeowners running this query in 2026 — and there are millions of them — those three names are the entire shopping list. They'll call one or two, book the appointment, and never touch Google.

If you weren't in that list of three, you didn't exist. Not for that customer.

The next thing I tried surprised me

I ran the same query 12 more times, varying the wording slightly:

• "best plumber in Columbus for drain cleaning"
• "who should I call for a clogged drain in Columbus Ohio"
• "recommend a plumber near downtown Columbus"
• "emergency plumber Columbus Ohio"

The same 4–6 businesses came up over and over. Different orderings, different phrasing in the recommendation, but the same names. The plumbers ChatGPT "knows" about in Columbus is a list of maybe 8 companies. The rest of the market — there are 50+ plumbers serving Franklin County — got zero mentions across 13 queries.

I checked Perplexity next. Same pattern, slightly different list. Then Google's AI Overview. Same again.

What's actually happening here

These AI engines aren't using a magic algorithm. They're trained on what already exists about your business on the internet — Google reviews, blog posts, news articles, citations on directory sites, mentions on Reddit, Facebook, and local forums.

A business with 200 Google reviews, regular blog posts about Columbus-specific plumbing issues, mentions on local home-services blogs, and a complete Google Business Profile with the right service categories — that business shows up.

A business with 47 reviews, no blog, no recent activity, and a one-line "We do plumbing!" Google profile — that business is invisible to ChatGPT. Doesn't matter how good they are at the actual work.

This is the new SEO and most contractors haven't heard of it yet

Five years ago, "ranking on Google" meant page-one organic results plus a Google Maps box. Done.

Today, customers are bypassing search entirely. They ask ChatGPT, Perplexity, or Gemini directly. The ones who do still search hit Google and see an AI Overview at the top that recommends 2–3 businesses inline, before the regular results.

The contractors winning right now figured this out 12 months ago. They've been quietly stacking citations, publishing real content with local detail, and showing up everywhere AI engines look for trustworthy mentions. They're not running ads — they don't need to.

The contractors who haven't started yet have a 12–24 month window before this fully shakes out. After that, the leaderboard locks in and catching up gets expensive.

Run the query on your own business

Open ChatGPT right now. Type:

"I need a [your trade] in [your city] for [your most common service]. Who would you recommend?"

If your name doesn't come up in the first answer, you're invisible to a growing chunk of the homeowners shopping in your service area right now.
