"I've done Google Ads and it was a fail."
We hear this from almost every plumbing, HVAC, and electrical contractor we talk to. They've been through Reach Local, Yodel, the kid across the street, an in-house hire — and every time, the result was the same: money spent, leads lacking.
Here's the truth: Google Ads work incredibly well for contractors. The problem isn't the platform. It's how the campaigns are set up.
The #1 Mistake: One Ad Group, One Landing Page
The biggest mistake we see is contractors (or their agencies) lumping all keywords into a single ad group and driving everything to the homepage.
Here's why that fails:
- Keywords aren't relevant to the ad — "drain cleaning" and "water heater installation" trigger the same generic ad
- The landing page doesn't match intent — someone searching for water heater repair lands on a general homepage
- Quality Score tanks — Google penalizes irrelevant ad-to-landing-page combinations
- Cost per click skyrockets — with $150–$200 clicks in competitive markets, irrelevance is expensive
The Right Way: Dedicated Campaigns, Dedicated Pages
Campaign Structure
Break your services into separate campaigns with targeted ad groups:
| Campaign | Keywords | Landing Page |
|----------|----------|-------------|
| Water Heater | water heater repair, water heater replacement, tankless water heater | /water-heater |
| Drain Cleaning | drain cleaning, clogged drain, drain service | /drain-cleaning |
| AC Repair | AC repair, air conditioning repair, AC not cooling | /ac-repair |
| Brand | [your company name] + variations | Homepage |
Landing Pages That Convert
Your paid traffic landing pages should be completely different from your organic website pages:
What a great landing page includes:
- Special offer (discount, free estimate) — paid visitors don't know you yet, give them a reason to choose you
- Request service form above the fold
- Phone number in the top left corner
- Clean, simple design — not busy or cluttered
- Mobile-optimized (most clicks come from mobile)
- Social proof (reviews, badges, years in business)
What it should NOT include:
- Full website navigation (too many exit paths)
- Long paragraphs of content
- Multiple service offerings on one page
- No clear call-to-action

The Secret Weapon: Conversion Tracking
You can't optimize what you don't track. Every Google Ads campaign needs:
- Call tracking — know which keywords generated which calls
- Form submission tracking — track every web form completion
- Revenue matching — connect leads to booked jobs in Service Titan/HouseCall Pro
- ROI reporting — know your return on every dollar by campaign
Without this, you're pulling the lever on a slot machine. With it, you're going to an ATM — predictable, consistent returns.
