Emergency calls versus scheduled jobs
A burst pipe at 9 p.m. and a water heater swap next Tuesday are different searches with different economics. The emergency caller converts in minutes and rarely compares three quotes; the scheduled job shops around. Put them in separate campaigns so the emergency budget never gets drained by research traffic, and run the emergency campaign only during hours when a dispatcher or on-call tech actually answers.
For the scheduled side, build ad groups around high-ticket services (water heater installation, tankless conversions, repiping, sewer line replacement) and send them to pages with price ranges and an online booking form.
Local Services Ads and Search ads together
Plumbers are one of Google's Local Services Ads categories in the US. You pay per lead rather than per click, and businesses that pass Google's screening get the Google Verified badge. LSA units often appear above the regular text ads, so a plumbing company that skips them gives up the first thing many searchers see.
LSA alone is not enough, though: you control little beyond service types, area and budget. Keep a Search campaign for the specific jobs you want more of, for the hours LSA budget runs out, and for queries where your own landing page and offer can outsell a generic listing.
What the keyword data tells you
"plumber" is marked Low competition yet carries the highest ceiling on the page at $87.36. The competition index counts how many advertisers bid, not how much they pay, so a handful of well-funded operators can push prices up on their own. "local plumber" and "plumber company" (10K to 100K searches each, up to $80.00) behave like the core term.
"plumber cost" is the bargain at $4.45 to $26.51, but those searchers are budgeting, not calling. Bid on it only with a page that shows real price ranges, and judge it on booked jobs rather than leads.
License numbers and claims in your ads
Licensing rules are set by states, and some reach into advertising. In California, the Contractors State License Board requires licensed contractors to include their license number in all forms of advertising, including websites and online posts. Put the number in the footer of every landing page and in your ad copy where space allows, and check your own state board before launch.
Avoid unverifiable superlatives such as "#1 plumber in town" unless you can back them up on the landing page; Google may limit or disapprove claims it judges misleading, and they rarely lift conversion anyway.
Call tracking now that call-only ads are going away
Google removed the option to create new call-only ads in February 2026, and existing ones stop receiving impressions in February 2027. The replacement is a responsive search ad with call assets. Use a Google forwarding number, count calls over 60 seconds as conversions, and import booked jobs from your CRM so Smart Bidding learns which calls make money.
Tight tracking is what makes a plumbing account work. On a French plumbing account managed by Discovery Digitals, it brought the cost per conversion down to €1.62 (3,820 conversions for €6,200). US clicks cost several times more, which makes clean conversion data even more valuable.
