You just spent $800 on Google Ads last month. Three calls came in. Two were small drip repairs that barely covered the ad cost. Your competitor down the road seems to be getting all the big jobs. What gives?
The answer is in your return on ad spend.
Why Return On Ad Spend Matters for Plumbers
Plumbing is a volume game, but not all jobs are created equal. A sewer line replacement pays differently than a $75 faucet repair. Here’s why tracking ROAS matters:
- Job value varies wildly. A toilet clog might earn you $150. A water heater install could be $2000. Raw call count means nothing if the wrong customers are clicking your ads.
- Service areas differ in profitability. Some neighborhoods have older homes needing constant repairs. Others have new construction where homeowners handle everything themselves.
- Competition drives up costs. In metro areas, Google Ads for plumbers can run $50+ per click. Without ROAS tracking, you could be bleeding budget on high-competition terms that never convert.
- Seasonal shifts impact results. Summer brings emergency AC calls. Winter freezes pipes. Your best-performing keywords change throughout the year.
How to Check in GA4
Google Analytics 4 gives you the foundation for ROAS tracking. Here’s how to find it:
- Set up conversion events. In GA4, go to Configure > Events. Mark your booking or call events as conversions.
- Link Google Ads. Connect your Google Ads account in GA4 under Settings > Google Ads links.
- Run the Ads performance report. Navigate to Advertising > Publisher ads > Ads overview. Look for conversion value divided by cost.
- Segment by campaign. Break down your data by campaign or ad group to see which plumbing keywords actually pay off.
The numbers will be there, but making sense of them takes time.
The Easier Way
Let ClawAnalytics do the heavy lifting. It automatically pulls your Google Ads data and shows you:
- Which plumbing keywords bring the highest-value jobs (not just the most calls)
- Whether you’re overspending on neighborhoods that never book
- How your ROAS compares to last month, last year
Example questions ClawAnalytics answers:
- “Did my $50/day budget on ‘emergency plumber near me’ actually pay off?”
- “Which zip codes generated the most revenue per ad dollar?”
- “Should I shift budget from ‘plumber’ to ‘water heater repair’?”
Instead of exporting spreadsheets and building pivot tables, you get clear answers.
Quick Wins
- Track actual job revenue, not just calls. Connect your booking software so ROAS reflects real money, not lead count.
- Use negative keywords aggressively. Add “jobs,” “salary,” “training” to filter out people looking for plumbing work, not plumbing service.
- Set ROAS goals per campaign. A 4:1 ROAS might work for drain cleaning but you need 6:1 for leak repairs to account for material costs.
- Review weekly, adjust monthly. Give campaigns time to learn, but don’t let bad performers burn budget past 2-3 weeks.
