The Google Ads Money Pit

You're spending $2,000/month on Google Ads. You're getting clicks. But you're not getting customers.

What's wrong?

Chances are, you're making one (or more) of these 7 common mistakes.

Mistake #1: Bidding on Broad Keywords

The Problem: Bidding on "plumber" gets you clicks from people across the country who can't use your services.

The Fix: Target "plumber near me" or "plumber [your city]". These searchers are ready to hire locally.

Result: Lower cost-per-click, higher conversion rate.

Mistake #2: Sending Traffic to Homepage

The Problem: Your homepage talks about everything. Visitors get confused and leave.

The Fix: Create dedicated landing pages for each service/keyword:

  • /plumbing-services
  • /emergency-plumber
  • /drain-cleaning

Result: 3-5x higher conversion rates.

Mistake #3: Ignoring Negative Keywords

The Problem: Your ad shows for irrelevant searches like "plumber salary" or "how to become a plumber."

The Fix: Add negative keywords:

  • salary
  • job
  • career
  • training
  • school

Result: Stop wasting money on useless clicks.

Mistake #4: No Conversion Tracking

The Problem: You don't know which keywords generate phone calls vs. just clicks.

The Fix: Set up:

  • Call tracking (which keywords drive calls)
  • Form tracking (which keywords drive form fills)
  • Revenue tracking (which keywords drive sales)

Result: Double down on what works, cut what doesn't.

Mistake #5: Weak Ad Copy

The Problem: Generic ads like "We Do Plumbing" don't stand out.

The Fix: Write compelling copy:

  • Headline: Specific benefit ("24/7 Emergency Plumber")
  • Description: Clear offer ("Free Estimates, Same-Day Service")
  • CTA: Action-oriented ("Call Now" not "Learn More")

Result: Higher click-through rates, better quality score, lower costs.

Mistake #6: Not Using Ad Extensions

The Problem: Your ad takes up less space, gets fewer clicks.

The Fix: Use all relevant extensions:

  • Sitelinks: Link to key pages
  • Callouts: Highlight benefits ("24/7 Service", "Free Estimates")
  • Structured Snippets: Show services
  • Call Extension: Direct phone number

Result: More real estate, more clicks, better ad rank.

Mistake #7: Set It and Forget It

The Problem: You launched your campaign 6 months ago and haven't touched it since.

The Fix: Weekly optimization:

  • Pause low-performing keywords
  • Increase bids on winners
  • Test new ad copy
  • Add negative keywords
  • Review search terms report

Result: Continuously improving ROI.

The Fix Checklist

  • [ ] Audit your keywords (remove broad, add local)
  • [ ] Create dedicated landing pages
  • [ ] Add negative keywords (at least 20-30)
  • [ ] Set up conversion tracking
  • [ ] Rewrite ad copy (benefit-focused)
  • [ ] Enable all ad extensions
  • [ ] Schedule weekly optimization time
