Most contractors waste 30–45% of their Google Ads budget on junk clicks. Here are 5 signs your agency isn't managing your campaigns well.

Is Your Google Ads Agency Wasting Money? 5 Signs

You're spending $2,000–$5,000 a month on Google Ads. Your agency sends you a report with impressions, clicks, and CTR. But you have a nagging feeling: is this actually working?

Here are 5 signs your agency might be burning your budget.

Sign 1: They can't show you a search term report

The search term report shows exactly what people typed into Google before clicking your ad. If your agency runs broad match keywords for "plumber," your ads might be showing for:

  • "plumber salary" (job seekers, not customers)
  • "plumber memes" (people looking for jokes)
  • "how to fix a toilet yourself" (DIY — they're not hiring you)
  • "plumber near me free estimate" (tire kickers)

You're paying for every one of those clicks.

What to do: Ask your agency to send you last month's search term report. If they hesitate or say they don't have it, that tells you everything.

Sign 2: You don't know your cost per lead

Your agency talks about impressions, clicks, CTR, and "conversions." But you need one number: how much does it cost to get a real lead?

Not a click. Not an impression. A human who called you or filled out a form and actually needs your service.

If your agency can't tell you this number, they're not tracking it. And if they're not tracking it, they can't optimize for it.

Benchmark for non-branded search: Plumbers: $130–$180 per lead. HVAC: $100–$170. Roofers: $150–$250. If your cost per lead is 2× these numbers or higher, your campaigns need work. (Branded search is much cheaper — often $30–$50 per lead — but doesn't bring in new customers.)

Sign 3: All your traffic goes to your homepage

Open your Google Ads account (or ask your agency) and look at where your ad clicks are landing. If every ad sends people to your homepage — that's a problem.

Your homepage talks about your company, your history, your team. A Google Ads landing page should do one thing: get the visitor to call you or fill out a form.

That means:

  • Phone number at the top
  • Short form (name, phone, problem)
  • Service-specific headline ("Emergency Plumbing in Dallas")
  • Social proof (reviews, badges)
  • No navigation menu (don't let them wander)

The difference matters: A service-specific landing page typically converts at 8–12%. A generic homepage converts at 2–4%. Same ad spend, 3x more leads.

Sign 4: No call tracking

Most home service leads come by phone. If your agency hasn't set up call tracking, they literally cannot tell you how many leads your ads generated.

"But we can see form submissions!" — Sure. That's maybe 20% of your leads. The other 80% called. Without call tracking, your agency is flying blind.

What to do: Ask if call tracking is set up. Specifically, are phone calls recorded as conversions in Google Ads? If not, Google's algorithm can't optimize for what actually makes you money.

Sign 5: They report monthly but nothing changes

Good agencies adjust your campaigns based on data. Every month, they should be:

  • Adding negative keywords (blocking irrelevant searches)
  • Pausing underperforming keywords
  • Testing new ad copy
  • Adjusting bids based on what's converting
  • Expanding into new service areas that work

If your monthly report looks the same every month and the strategy hasn't changed, you're paying a management fee for maintenance, not management.

The bottom line

Your agency works for you, not the other way around. You should be able to answer these three questions:

  1. What is my cost per lead? (not cost per click)
  2. What are people searching before they click my ad? (search term report)
  3. How many real leads did I get this month? (tracked calls + forms)

If you can't answer all three, your agency isn't giving you what you need.

Frequently Asked Questions

How do I know if my Google Ads agency is good?
Ask for three things: a monthly search term report (shows what people searched before clicking your ad), your cost per lead broken out by branded vs non-branded campaigns (not cost per click), and conversion tracking setup (phone calls and form submissions should be tracked as conversions). If your agency can't provide all three, they're not managing your account properly.
What percentage of Google Ads budget is typically wasted?
Industry research estimates that the average home service contractor wastes a large share of their Google Ads budget on clicks that never become leads. Common causes include irrelevant search terms from broad match keywords, missing negative keyword lists, and traffic sent to generic homepages instead of dedicated landing pages. A strong negative keyword list alone can cut wasted spend by 30% or more.
Should I manage Google Ads myself or hire an agency?
If you're spending less than $2,000/month, it's often better to learn the basics yourself or use an audit tool to monitor your campaigns. At $5,000+/month (the median for plumbing contractors), a good agency can optimize better than most business owners — but 'good' is the key word. Always ask for the three things mentioned above before hiring.
