Plumber Local SEO Benchmarks: How 29 Ranking Plumbers Score
We ran the same 12-check Trinity audit we use on real leads against 29 plumbers already ranking in the Google Maps top 20 across Las Vegas, Phoenix, Denver, Dallas, and Tampa. This is what the businesses getting the calls actually look like under the hood.

Fail rate by check — ranking plumbers
Percent of the 29 scored plumbers that fail each check. Orange = the majority-fail zone.
Mobile page speed (check #12) was not measured in this study — scores are out of 12 with the speed check never failing. n = 29.
The 3 checks plumbers fail most
In plain language — what each miss costs, and why fixing it matters.
Hours in the footer let Google cross-check the website against the Business Profile — and let a customer searching at 9pm know you'll pick up. No hours means a trust gap and lost after-hours calls.
The main headline should say the service and the city — 'Plumber in Phoenix,' not 'Welcome to Our Website.' It's the single loudest on-page signal for which searches the site belongs in.
A Google Map embed on the homepage is the easiest 'yes, this is the same business at the same address' proof Google can get. Skip it and Google has to work harder to trust the listing.
What this means if you're a plumber
Every business in this benchmark is already in the Maps top 20 — they're the ones getting the calls in their city right now. And the average one still passes only 8.48 of 12 checks (median 8).
That's within 0.09 of the 175-business average of 8.39 — right in the pack. 10.3% of ranking plumbersscored under 7 of 12, the threshold where we'd flag a site for a full rebuild. The trade is a tie waiting for a tiebreaker.
Look at the top of the chart again: 79.3% of the plumbersalready outranking you fail the "Hours of operation in footer" check, and 72.4%fail "H1 headline (city + service)". Those aren't hard fixes — they're signals Google and AI tools read every time they decide who shows up. Pass the checks your competitors fail and you stop losing tiebreakers to businesses no better than yours. More people finding you → more calls → more jobs.
