Are You Wasting $5,000+ Per Month on Google Ads?

The 5 Biggest Sources of Wasted Ad Spend

We've audited hundreds of contractor Google Ads accounts. The same 5 problems show up in nearly every one:

1. Broad match keywords running unchecked. Google matches your ads to searches that have nothing to do with your business. An HVAC company bidding on "AC repair" gets matched to "AC repair DIY tutorial" and "AC repair technician jobs hiring." Every click costs you money. Zero of those clicks book a job.
2. No negative keyword lists. Without negative keywords, you're paying for searches like "free," "DIY," "salary," "jobs," and "complaints." A plumber spending $3,000/month without negative keywords can burn $600-$900 on searches that will never convert.
3. Homepage as landing page. Sending paid traffic to your homepage forces the visitor to figure out what to do next. Dedicated landing pages with a single call to action convert 2-3x better than a homepage. Every click that bounces is wasted budget.
4. No call tracking. If you can't see which keywords produce phone calls, you're flying blind. You keep funding keywords that generate clicks but never ring your phone.
5. Generic ad copy. Ads that say "Quality Service, Call Today" compete with every other contractor using the same lazy template. Specific, trade-relevant copy with a clear offer pulls more clicks from the right people and fewer from tire-kickers.

Average Waste Rates by Trade

Not every trade wastes the same amount. Some industries have more irrelevant search traffic, higher CPCs, and more competitive auctions. Here are the averages we see across managed accounts:

• HVAC: 38-45% waste rate. High CPC and heavy DIY search volume drive most of the waste.
• Plumbing: 42-50% waste rate. "Plumber near me" pulls in everything from job seekers to DIY drain cleaners.
• Roofing: 35-42% waste rate. Lower waste percentage, but the highest CPCs in home services make every wasted click expensive.
• Tree Service: 30-38% waste rate. Lower competition means less waste, but geographic targeting issues still bleed budget.
• Electrical: 40-48% waste rate. "Electrician" triggers job-seeker and licensing searches that eat budget fast.
• General Contractor: 45-55% waste rate. The broadest keyword set means the most irrelevant traffic.

How to Cut Your Waste Rate in Half

The fix isn't complicated. It just requires discipline and weekly attention:

• Switch to exact match and phrase match keywords. Stop letting Google decide what your ads match to. Control the search terms you pay for.
• Build dedicated landing pages for each service. "AC Repair in [City]" should land on a page about AC repair with a phone number and form, not your homepage.
• Add a negative keyword list on day one and update it weekly. Review your Search Terms Report every Monday. Block anything that isn't a real customer looking for your service.
• Install conversion tracking and call tracking. If you can't measure which keywords produce booked jobs, you can't cut the losers.

When Google Ads Waste Becomes a Bigger Problem

Here's the trap: most contractors respond to poor results by spending more. They throw another $1,000/month at the campaign hoping to see more calls. But scaling a broken campaign just scales the waste. If you're wasting 45% at $3,000/month, bumping to $5,000/month means you're now wasting $2,250 instead of $1,350. The percentage stays the same. The dollar amount gets worse. Fix the waste first, then scale.
