How I Helped an Austin Plumbing Company Scale From 5 Calls a Day to 15 by Targeting "Leak Detection" Keywords

When this Austin plumber called me, the shop was doing about 5 booked calls a day. Drain clears, water heaters, the usual stuff. Decent business. Boring rankings. The owner had been paying an agency in another state $2,400 a month for a year, and the only thing they'd grown was the invoice.

Five months later, the same shop is averaging 15 booked calls a day, with a heavier mix of high-ticket work. The play that moved the needle the most wasn't some clever link campaign. It was deciding to go all in on one keyword family the agency had completely ignored: leak detection.

Here's exactly what I did, why it worked, and how you can pull the same play in your own city.

Why "leak detection" and not "plumber Austin"?

Every plumber in Austin is fighting for "plumber Austin," "plumbing near me," and "emergency plumber." The big franchise shops own the top of that map pack and they're not handing it back. You can grind for a year and barely budge.

Leak detection is different for three reasons:

• Higher intent. Nobody types "leak detection Austin" because they're curious. They type it because their water bill just tripled or there's a wet spot on the slab. They're calling someone today.
• Higher ticket. A leak detection call in Austin lands somewhere between $350 and $700 just to find the leak. Then you've got the repair on top, which is often a re-pipe, a slab leak repair, or a yard line replacement. That's $2k to $15k of work behind a single phone call.
• Lighter competition. Most Austin plumbers list "leak detection" as one of fifteen services on a stock page. Almost nobody has a real page built around it, let alone a cluster.

So instead of trying to take ground in the most expensive part of the market, I picked a part of the market the bigger shops were sleeping on.

Step 1: I pulled apart who was actually ranking

Before I touched the site, I spent a couple of hours pulling apart the top five organic results and the top five map pack results for every leak-detection variant I could find. I looked at:

• Page word count and section structure.
• Whether the page mentioned slab leaks, pool leaks, pinhole leaks, and yard line leaks by name.
• Whether the Google Business Profile had "Plumber" as the primary category and what services were attached.
• How many reviews mentioned the word "leak" in the actual review text.

The pattern was clear. The pages that ranked were specific. They talked about slab leak detection in Austin instead of "we offer leak detection services." They named neighborhoods. They had photos of actual equipment. And almost none of them had real review proof tied to leak work.

That last one was the gap I wanted to walk into.

Step 2: I built a real leak-detection content cluster

The site had one sad page that said "We offer leak detection in Austin and surrounding areas." That was it. I scrapped it and built a small cluster around the topic.

One pillar page targeting Leak Detection in Austin, TX. Then five supporting pages, each one going deep on a real version of the job:

• Slab leak detection in Austin (this is huge in Austin because of the post-tension and pier-and-beam mix, and because the clay soil moves).
• Pool leak detection in Austin.
• Yard line and main water line leak detection.
• Pinhole leak detection in copper repipes.
• How much leak detection costs in Austin (this one became the top traffic page within 90 days).

Every page followed the same shape. A short, blunt intro that named the problem. A section on what the actual job looks like, including what equipment I'd be rolling up with. A pricing section with real ranges. A section naming the Austin neighborhoods I see the most of this work in (Tarrytown, Allandale, Circle C, Steiner Ranch, Westlake, Cedar Park edges). Photos of jobs. A FAQ block. A clear "call now" CTA above the fold and at the bottom.

No fluff. No "premier provider." No stock photos. Just answers a panicked homeowner with a $400 water bill actually wants to read.

Step 3: I rebuilt the GBP around the same keyword family

The Google Business Profile had been treated like a glorified business card. I went in and did the boring work nobody wants to do:

• Confirmed primary category was Plumber, added Water damage restoration service as a secondary, then attached every leak-related service Google offered. "Leak detection" went on as a custom service with a 200-word description.
• Wrote out the service area as the actual zip codes the shop serves, not "Austin and surrounding."
• Loaded 40+ real job photos with proper filenames and geotags. Slab leak jobs, jackhammered floors, pool equipment pads, pressure tests, the whole bit.
• Started a weekly Google Post that was always tied to a real leak job from that week. "Found a slab leak in 78704 yesterday under the dining room slab. Here's what the thermal camera showed." Real, specific, never recycled.

Then I built a review ask into the dispatch workflow. Every leak detection job ended with a text that pointed straight at the GBP and asked the customer to mention what kind of leak it was. Inside two months, the review profile went from generic "great service" to a wall of specific leak stories with neighborhood names baked in. Google reads that text. So do buyers.

Step 4: I went after the AEO side too

This is the part most plumbing SEOs are still ignoring. A real chunk of the buyers who used to type into Google are now typing into ChatGPT, Perplexity, and Gemini, or hitting the AI Overview at the top of the search page. They ask things like "best leak detection plumber in Austin under $500" or "who finds slab leaks in south Austin."

To show up in those answers I rewrote every page in the cluster so the first 100 words directly answered the question the page was about. Plain English. No throat-clearing. Then I added a clean FAQ block with the most common phrasings of that question.

I also got the company added or fixed on the citation sources the AI models actually pull from. Not the 200-citation directory dumps the agencies sell. The ones that matter: Yelp, BBB, Angi, HomeAdvisor, the Austin Chamber, Nextdoor neighborhood favorites, and a handful of local "best plumbers in Austin" roundup pages I earned a mention on.

What the phone log looked like 5 months in

The owner tracks every inbound call by source. Here's roughly what the change looked like, month by month, just for the leak-detection side of the business:

• Month 1: About 4 leak-related calls. Mostly from existing customers. Pages were live but Google hadn't really moved them yet.
• Month 2: 11 leak calls. The pricing page started ranking on page one for "leak detection cost Austin." GBP started showing in the map pack for "slab leak detection Austin."
• Month 3: 24 leak calls. First month the shop did more than $20k in leak-related revenue from new customers.
• Month 4: 41 leak calls. The pillar page hit position 3 organically. The map pack ranking went top 3 in most south and central Austin zips.
• Month 5: 58 leak calls, and total daily booked jobs across the whole shop averaged 15 a day, up from 5.

And the mix shifted. The average ticket on a leak call closed somewhere around $1,900, because so many of them turned into a repair. That's a different business than running drain clears all day.

Three things you can steal from this play

If you run a plumbing shop in any city and you're tired of grinding against the franchises on "plumber [city]," here's what I'd actually do this week:

1. Pick one high-ticket, high-intent service. Leak detection, tankless installs, repipes, sewer line replacement, water heater installs. Pick one. Don't try to fix everything at once.
2. Build a real cluster around it. One pillar page, four or five deep supporting pages, all linking to each other. Name your city. Name your neighborhoods. Name your equipment. Show real photos.
3. Make your GBP and your reviews say the same thing. If you want to rank for leak detection, your GBP services, your posts, and your reviews all need to use that language. Most plumbers do this by accident, badly. Do it on purpose.

That's it. No magic. No black-hat link scheme. No 40-page strategy document. Just picking the right fight and showing up like someone who actually does the work.
