5 Ways Contractors Waste Money on Google Ads (And How to Fix It)
Most contractor Google Ads campaigns are quietly hemorrhaging budget. Here are the five most common mistakes we see — and exactly how to fix them.
If you've ever run Google Ads for your contracting business and thought "this doesn't seem to be working," you're not alone.
Most contractor campaigns we inherit are wasting 40–60% of their budget. Not because Google Ads doesn't work — it absolutely does for service businesses — but because the campaigns are set up wrong in ways that aren't obvious until you know what to look for.
Here are the five mistakes we see most often.
1. Running Broad Match Keywords Without Negative Keywords
Broad match keywords like "plumber" or "roofing" sound reasonable, but they trigger ads for searches like "plumber salary," "roofing DIY," and "how to become an electrician." You're paying for clicks from job seekers and curious homeowners, not people who need to hire someone today.
The fix: Use phrase match or exact match for your core keywords, and build an aggressive negative keyword list from day one. Review your Search Terms report weekly for the first month and add anything irrelevant.
2. Sending Ads to Your Homepage
Your homepage is built to explain your whole business. An ad click is someone ready to take one specific action. When those two things don't match, you lose the lead.
The fix: Build dedicated landing pages for each service or campaign. A "emergency plumber near me" ad should go to a page that screams emergency plumbing, has your phone number front and center, and has one call to action.
3. Running Ads 24/7 When Your Business Isn't
If you don't answer calls at 2am, don't run ads at 2am. You're paying for clicks you can't convert.
The fix: Use ad scheduling to match your business hours. If you do offer after-hours service, make sure your landing page reflects it and you have a system to capture those leads.
4. Ignoring Quality Score
Quality Score is Google's rating of how relevant your ad, keyword, and landing page are to each other. A low score means you pay more per click for worse ad positions. Most contractors set up their campaigns and never look at this.
The fix: Match your keywords, ad copy, and landing page content tightly. If your keyword is "roof repair Austin," your ad should mention roof repair in Austin, and your landing page should be about roof repair in Austin. It sounds obvious but most campaigns miss this.
5. Not Tracking Phone Calls as Conversions
Most contractor leads come in via phone. If you're only tracking form fills, you're flying blind on what's actually working. We see campaigns all the time where the client thinks it's not working — but actually they're getting 15 calls a month they have no way to attribute.
The fix: Set up call tracking through Google Ads or a third-party tool. Import call conversions so your campaigns can optimize for what actually makes you money.
Getting Google Ads right for a contractor business isn't complicated, but it does require attention to these details. If you're running campaigns now and not happy with the results, we're happy to take a look and tell you honestly where the budget is going.
