The Key Insight
Appliance repair is a search-driven business. Nobody browses for a technician - the Sub-Zero stops cooling and the homeowner types the brand, the problem and the city into Google within the hour. That makes Google Ads the right channel, and it also makes it an expensive one: every competitor is bidding on exactly the same moment, because the job behind it is worth $4,000-$5,000.
So the lever was never the bid. It was the structure.
We stopped running 5Star Appliance Repair as one national advertiser and rebuilt both brand accounts city by city. Los Angeles, Seattle, Miami, New York, San Diego, San Francisco and San Jose each got their own campaign, budget, bid logic and ad schedule tied to when people in that time zone actually book. A dollar in San Jose stopped subsidising a dollar in New York, and within a week it was obvious which cities deserved more.
The second lever was subtraction. Appliance search is full of traffic that will never book: how-to videos, spare parts, warranty numbers, manuals. We reworked the negative keyword lists every week and kept the budget on queries that carry real intent - brand, appliance, problem, city. That discipline is what held the click-through rate at 3.3% to 4.1%, which in a category this competitive is the number that tells you the ad matched what the person actually typed.
The third lever was the landing page. One generic page for seven metros gives a homeowner in Miami no reason to trust the visit. City-specific pages with local proof, plus continuous A/B testing on the CTA, the form and the layout, turned the same traffic into more booked jobs without raising a single bid.
What that adds up to: roughly $1,140,000 in ad spend since February 2019, 6,370 tracked conversions and 7,080 phone calls at about $179 per conversion, and in the client's own reporting somewhere between $18M and $22M in revenue at a $4,000-$5,000 average ticket. Sixteen to nineteen times the ad spend.
One honest caveat, and it matters more than the account: at $4,000-$5,000 a job you can afford an expensive click - what you cannot afford is a missed call. The ceiling here was never the bidding. In the client's own reporting the leads that went cold were the ones nobody called back fast enough. Google Ads buys the phone call. The follow-up is what turns it into a $4,000 invoice.
