Google Ads can be the fastest way to get calls for your contracting business. Or it can be the fastest way to light money on fire. The difference comes down to about 5 things that most contractors and their agencies get wrong.
If you're spending $1,000-3,000 per month on Google Ads and you can't point to exactly how many calls and jobs that spend generated, this article is for you. Let's fix it.
Problem 1: Sending Ads to Your Homepage
This is the most common mistake and the most expensive one. You set up a Google Ads campaign for "AC repair Tampa," someone clicks your ad, and they land on your homepage. Your homepage that talks about all 12 services you offer, has a slider with stock photos, and buries the phone number in the footer.
That click cost you $15-40 depending on your market. And the person bounced in 3 seconds because they couldn't immediately find what they searched for.
The Fix: Dedicated Landing Pages
Every ad group needs its own landing page. If someone searches "AC repair Tampa," they should land on a page that says "AC Repair in Tampa" in the headline, has your phone number above the fold, shows your Google reviews, lists your AC repair services, and has one clear call-to-action: call now or fill out a short form.
Nothing else. No navigation menu. No links to your other services. No distractions. The page has one job: get that visitor to pick up the phone.
Contractors who switch from sending ads to their homepage to using dedicated landing pages typically see conversion rates jump from 3-5% to 12-20%. On a $2,000/month ad spend, that's the difference between 6 calls and 24 calls. Same budget. Four times the results.
Problem 2: Not Tracking Calls
You'd be amazed how many contractors are spending $2,000 a month on Google Ads and have no idea how many phone calls those ads generate. They look at their Google Ads dashboard, see "50 clicks," and assume some of those turned into calls. Maybe. Maybe not.
Without call tracking, you're flying blind. You don't know which keywords are generating calls. You don't know which ads are working. You don't know if your $2,000 is generating $20,000 in jobs or zero.
The Fix: Set Up Call Tracking
At minimum, enable Google Ads call tracking. This is free and built into the platform. It tracks calls that come directly from your ad (the call extension) and calls that happen after someone clicks through to your website.
For better data, use a tool like CallRail ($45/month). It gives you a unique phone number for your landing pages that forwards to your real number. Every call gets recorded, tagged with the keyword that triggered it, and logged with the call duration. Now you know that "emergency plumber Tampa" generated 8 calls last month and "plumbing services Tampa" generated 1. You can shift your budget accordingly.
Call tracking also lets you listen to actual calls. You'll hear which calls are real customers and which are spam, tire-kickers, or wrong numbers. That data is gold for optimizing your campaigns.
Problem 3: Broad Match Keywords Are Eating Your Budget
Google Ads has three keyword match types: broad match, phrase match, and exact match. If you don't understand the difference, Google will happily spend your money on searches that have nothing to do with your business.
Broad match "plumber Tampa" means Google will show your ad for anything Google thinks is related. That includes "plumber salary Tampa," "plumbing school Tampa," "how to become a plumber," "Tampa plumber reviews" (people researching, not hiring), and sometimes completely unrelated searches that Google's algorithm loosely connects.
You're paying $15-40 per click for people who are looking for plumbing school. That's your money. Gone.
The Fix: Use Phrase Match and Exact Match
Phrase match "plumber Tampa" means your ad shows when someone searches that phrase or close variations of it in that order. Much tighter. "Emergency plumber Tampa" would trigger your ad. "Plumber salary Tampa" would not.
Exact match [plumber Tampa] means your ad only shows for that exact search or extremely close variants. Tightest control. Fewest wasted clicks.
Start your campaigns with phrase match. Once you have data on which searches convert into calls, add the best performers as exact match keywords with higher bids. This ensures your budget goes to the searches that actually book jobs.
As a general rule for contractors: phrase match for your main service keywords, exact match for your proven money keywords, and never use broad match unless you're running a discovery campaign with a very small daily budget specifically to find new keyword ideas.
Problem 4: No Negative Keywords
Negative keywords tell Google which searches you don't want to show up for. Without them, you're paying for clicks from people who will never hire you.
Here's a list of negative keywords every contractor should add on day one:
- "jobs" and "hiring" - people looking for employment, not service
- "salary" and "pay" - same reason
- "school" and "training" and "certification" - students, not customers
- "DIY" and "how to" - people who want to do it themselves
- "free" - people who don't want to pay
- "reviews" - people in research mode, not buying mode (debatable, but usually low intent)
- "cheap" and "cheapest" - attracts price shoppers who haggle and leave bad reviews
- Names of cities you don't serve
- Competitor business names (unless you're intentionally running competitor campaigns)
Check your search terms report every week. Google Ads shows you exactly what people searched before clicking your ad. Every time you see a search that's not a real customer, add it as a negative keyword. This is an ongoing process, not a one-time setup.
Most contractors who start reviewing their search terms report for the first time are shocked. They find that 30-50% of their clicks are from searches that will never turn into a job. That's 30-50% of their budget wasted. Every month.
Problem 5: Not Optimizing for Calls
Google Ads lets you optimize for different goals: clicks, impressions, conversions, or specific conversion types like phone calls. Most contractor campaigns are set to optimize for clicks by default. That means Google is showing your ads to people most likely to click, not people most likely to call.
There's a big difference. Someone who clicks and browses your site for 10 seconds cost you $20 and generated nothing. Someone who clicks and calls you is a potential $500 job.
The Fix: Optimize for Call Conversions
First, set up conversion tracking for phone calls (from your website and from ad call extensions). Let the campaign run for 2-3 weeks to collect data. Once you have at least 15-20 call conversions, switch your bidding strategy to "Maximize Conversions" or "Target CPA" (cost per acquisition).
Now Google's algorithm knows what a valuable click looks like for your business. It will automatically bid higher for searches and audiences that are more likely to call and bid lower for those that just browse.
This single change can cut your cost per call by 30-50% within a month. Google's machine learning is very good at this once it has enough data to work with.
Use Call-Only Ads
For service contractors, call-only ads are underused and extremely effective. Instead of sending someone to a landing page, the ad triggers a phone call directly when tapped on mobile. No landing page, no extra step, no chance to bounce.
Call-only ads work best for emergency services: plumbing leaks, AC breakdowns, lockouts, electrical issues. Someone searching "emergency plumber near me" at 11 PM on a Saturday doesn't want to browse a website. They want to call someone right now. A call-only ad puts your phone number in front of them instantly.
Run call-only ads alongside your standard search ads. Split your budget: 60% to landing page campaigns for non-emergency keywords, 40% to call-only campaigns for emergency and urgent keywords.
Problem 6: Your Landing Page Is Killing Your Conversions
Even if your campaigns are set up perfectly, a bad landing page will waste every click you pay for. Here's what a contractor landing page needs:
Above the Fold (What They See Without Scrolling)
- Headline that matches the search: "AC Repair in Tampa - Same Day Service"
- Phone number, large and clickable
- Short form: name, phone, brief description of problem (3 fields max)
- One trust signal: "4.9 stars on Google - 127 reviews"
Below the Fold
- 3-5 Google reviews (real screenshots or pulled from your profile)
- List of specific services related to the search
- Your service area with city names
- Photos of your work, truck, or team (real, not stock)
- License number, insurance info, years in business
- Another phone number and form at the bottom
What to Remove
- Navigation menu - don't give them an exit
- Links to other pages - keep them on this page
- Long paragraphs of text nobody reads
- Sliders or carousels - they slow the page and nobody clicks them
- Anything that doesn't directly support the decision to call
The landing page should load in under 2 seconds on mobile. Test it on Google PageSpeed Insights. If it's slow, you're paying for clicks and then losing the visitor before they even see the page. That's the most expensive kind of waste.
Problem 7: No Ad Schedule
If your ads run 24/7 and nobody answers the phone at 3 AM, you're paying for calls you can't take. Missed calls don't leave voicemails. They call the next contractor on the list.
The Fix
Set an ad schedule that matches your hours. If you answer calls from 7 AM to 8 PM, run your ads from 6:30 AM to 8:30 PM (the buffer catches early and late searchers). Reduce bids by 50% or pause entirely during hours when nobody is answering.
Exception: if you have an answering service that takes calls 24/7, run ads around the clock. Emergency services like plumbing and HVAC get some of their highest-intent clicks between 9 PM and 6 AM. A homeowner with a flooded basement at midnight will pay whatever it takes. If you can answer that call, those late-night clicks are worth every penny.
The Real Numbers: What Good Google Ads Look Like for Contractors
Here's what a well-optimized Google Ads campaign looks like for a contractor:
- Cost per click: $8-25 depending on market and service
- Landing page conversion rate: 12-20%
- Cost per call: $40-100
- Call to job close rate: 30-50%
- Cost per booked job: $80-300
- Average job value: $300-1,500
- Return on ad spend: 3x-10x
If your numbers don't look like this, one or more of the problems above is draining your budget. The good news is every one of these problems is fixable. Some of them in an afternoon.
The Quick Win Checklist
If you're running Google Ads right now, do these things this week:
- Check your search terms report. Add negative keywords for every irrelevant search.
- Switch from broad match to phrase match on all keywords.
- Set up call tracking if you don't have it.
- Build a dedicated landing page for your top campaign - or at minimum, make sure your phone number is above the fold on whatever page you're sending traffic to.
- Set an ad schedule that matches when you actually answer the phone.
These five changes alone can cut your wasted spend in half and double your calls. No increase in budget. No new campaigns. Just fixing the leaks in what you already have.
Google Ads works for contractors. It works really well. But only when the campaigns are set up to generate calls, not clicks. Clicks cost you money. Calls make you money. Build everything around that distinction and the results follow.
