The 5 dumbest mistakes plumbers make on Google.

We audit a lot of plumber marketing accounts. Hundreds at this point. And we keep seeing the same five mistakes — at every business size, in every market.

None of these are subtle. They're all preventable. And most of them you can fix yourself this weekend. Here they are, in rough order of how much money they're costing you.

1. Your Google Business Profile is half-finished

Your GBP is the single most important free asset you own as a plumber. It's what shows up in the Maps 3-pack. It's what drives the "call" button on someone's phone. It's the listing that gets pulled into Google Verified, AI summaries, and basically every local search experience.

And most plumbers have one that's 40% filled out.

What's usually missing:

• Services list (with descriptions for each one)
• Real photos — not stock images, not your logo, not screenshots
• Posts (GBP has a post feature most plumbers don't even know exists)
• Q&A section, with the most common questions you actually get
• Service area defined properly (it's not "the whole metro," it's specific zip codes)
• Hours, payment types, booking link, attributes

The fix: Spend 90 minutes filling out every field on your GBP. Add 20 real photos. Write a service description for each service. Answer the top 5 questions customers ask. Set a 60-day reminder to do it again. (A complete, well-fed profile is also the foundation of our plumber SEO approach — everything else compounds on top of it. And if your profile ever gets suspended, don't panic — there's a specific recovery path.)

2. You sent your Facebook ad traffic to your homepage

Cold Facebook traffic doesn't know your business. They were scrolling, your ad caught their eye, and now they have three seconds of patience before they bounce.

Your homepage is built for someone who already knows you. It has nav menus, multiple CTAs, paragraphs of company history. By the time a cold visitor figures out what they're supposed to do, they're gone.

The fix: For Facebook campaigns, use Meta's native lead forms — pre-filled with the user's profile data, two-tap submission, no leaving the app. Conversion rates are typically 3–5x higher than sending traffic to a website. We use lead forms on almost every Facebook ads for plumbers campaign we run.

If you do send to a landing page (for higher-intent offers), it should be a single page with one offer, one form, one phone number. Not your homepage.

3. You're not disputing bad leads in your LSAs

Google Local Services Ads charge you per lead — but they also let you dispute leads that are clearly outside your service area, the wrong service type, spam, or otherwise not real. Most plumbers don't even know this exists.

If Google agrees with your dispute, they refund the lead cost. We've seen plumbers recover 15–25% of their LSA spend this way.

The fix: Set a calendar reminder every Friday to review your LSA leads from the week. Dispute every legitimate case. The pattern is: wrong service category, outside service area, didn't book (after multiple call attempts), or obvious spam.

4. Your website takes four seconds to load

Mobile users — which is 70%+ of your plumbing traffic — will bounce if your site takes more than 3 seconds to load. Most plumber websites we audit take 4–7 seconds.

This kills you twice:

• Customers leave before they see your phone number
• Google ranks your site lower because of slow load speed

The fix: Run your site through Google PageSpeed Insights (free). If you score under 90 on mobile, your site is costing you jobs. The fixes are:

• Compress your images (most plumber sites have 8MB+ of unoptimized photos)
• Remove unnecessary plugins, trackers, and chat widgets
• Don't use Wix or Squarespace for a high-traffic plumber site — they're slow by design
• Use a modern framework or platform built for performance

If you don't know how to fix any of this, hire someone who does. Or use it as evidence that you need a new plumber website built to convert — we get into exactly why a cheap build costs more in the long run in this breakdown.

5. You're optimizing for vanity keywords instead of money keywords

This is the most expensive mistake on the list, because it makes every other channel less effective.

Vanity keyword: "best plumber in [city]" — high impressions, lots of clicks, basically zero buying intent.

Money keyword: "emergency water heater repair near me" or "burst pipe plumber 78704" — lower volume, but the person typing it is about to spend $400.

Most plumbers (and most agencies) chase the vanity keywords because they look good in a report. The money keywords are what actually pay your bills.

The fix: Look at your Google Search Console data for the last 90 days. Sort by clicks. Now sort by conversion value (calls, form submissions, bookings). The keywords that look the busiest aren't the same as the keywords that make you money. Target the money keywords. Let the vanity ones happen on their own.

The pattern underneath all five

Every mistake on this list has the same root cause: doing marketing without a feedback loop.

You're guessing at what works instead of measuring it. You're chasing impressions instead of jobs. You're optimizing for what your agency reports instead of what your bank account shows.

The plumbers who win are the ones who treat their marketing like their service trucks: they track every job, measure every cost, and don't keep doing what isn't working.

Fix these five and you'll close the worst leaks in your current marketing. After that, the question becomes — how do you actually scale the things that are working? That's what we cover on a discovery call.
