Google Ads for Contractors: A PPC Guide With Real Numbers

Google Ads works for contractors when three things are already true. Your phones get answered, you can tell which calls became jobs, and you know which searches you want to pay for. If any of those is missing, the money goes to Google and the calls go to voicemail.

For most home service companies, Google Ads is the second paid channel, not the first. Local Services Ads usually come first because they charge per lead and sit at the top of the page. Google Ads then fills the gaps: planned, high-ticket work, job types LSA doesn't cover for you, and the exact searches you want with a landing page built for each one.

This guide is built on what we see in the contractor accounts we manage. That includes the Local Services Ads numbers from 7 accounts and a full Keyword Planner pull from a plumbing client's own Google Ads account. Where a number comes from outside, we name the source. We are not going to quote Google Ads results we don't have.

These are two different products from the same company, and contractors mix them up all the time.

The junk protection row matters more than people think. Across our 7 LSA accounts, 34 of 1,238 charged leads were credited back after a dispute, or 2.7%. Google Ads has nothing like that. Google filters out clicks it decides are invalid, but a homeowner in the wrong city or a job seeker who clicks your ad is a paid click. Your keyword list is the protection.

If you are deciding between the two, our LSA vs Google Ads comparison walks through which to run first for each trade. For paid versus the map and your website, see SEO vs PPC for contractors. The rest of this page assumes you have decided to run Google Ads and want to run it well.

LocaliQ's 2026 search ad benchmarks put home and home improvement at $8.33 per click, with a 6.47% click-through rate and an 8.05% conversion rate. Divide the click cost by the conversion rate and you get about $103 per call or form on average. That is a national average across every kind of home business.

Local trade searches are a different market. In August 2026 we pulled Keyword Planner inside Biz-E-Bee Plumbing & Rooter's own Google Ads account, for Riverside and San Bernardino counties, covering July 2025 to June 2026. These are Google's top-of-page bid ranges, meaning its estimate of what advertisers paid to show at the top. They are not what anyone actually paid per click.

Three things stand out.

Emergency searches cost the most. "Emergency plumber" topped out at $130.68. That is the same urgent call Local Services Ads charge for per lead, which is why we let LSA carry most of the emergency work and run Google Ads there only as overflow.

The big "near me" searches are expensive and broad. "Plumber near me" had 9,900 searches a month and a $31.59 to $90.00 range. That is a lot of volume, and also a lot of people who want a $79 drain clearing when you want a repipe.

Planned and research searches are cheap. "Tankless water heater cost" ran $0.47 to $9.10. Those homeowners aren't calling tonight, but they are shopping for a job worth thousands. This is where Google Ads beats LSA, because you can send them to a page that answers the price question and asks for the estimate.

Your trade and city will have different numbers. Pull Keyword Planner inside your own account for your own service area before you set a budget. National averages hide the spread.

A common structure problem is one campaign with every keyword in it. Urgent calls and planned projects behave so differently that one budget and one schedule can't serve both.

The urgent campaign

Urgent searchers want to talk to someone now. Run these as call-focused ads with a call asset, and only during hours someone will actually pick up. If LSA is already live, treat this campaign as overflow. Keep the budget small and the bids capped, because these are the most expensive clicks in the account.

Hours matter more than most owners expect. Across our 7 LSA accounts from November 2025 to mid-October 2026, phone leads were answered for 30 seconds or more 78.6% of the time on weekdays from 8am to 5pm. On weekday evenings and early mornings that fell to 65.3%. On weekends it was 46.3%. Paying $100 for an emergency click on a Saturday you won't answer is the fastest way to waste a budget.

The planned campaign

Planned work is where Google Ads earns its place. Replacements, installs and upgrades have bigger tickets and longer decisions. Give each job type its own ad group and its own landing page, with the price range, financing, license number and photos of real jobs. Form fills and estimate requests count here, not only calls.

For Biz-E-Bee's plan we built six non-brand search campaigns: emergency, core "plumber near me", drain and rooter, water heaters, leaks and slab, and sewer and gas. Each has its own keywords and its own budget, so a spike in drain clicks can't eat the money set aside for water heater installs.

Match types, briefly

Phrase and exact match keep you close to the searches you chose. Broad match lets Google decide what counts as related, which can work once the account has months of tracked calls behind it. On a new account we start with phrase and exact, read the search terms report every week, and only open up from there.

Negative keywords tell Google which searches never to show you for. On LSA you can dispute a junk lead. On Google Ads you can't get a bad click back, so this list does the work a dispute would. Load it before the first click. At $30 to $90 per click, an account with no negatives can burn real money in a single afternoon.

These come from the negative list we built for Biz-E-Bee. The product search row is a good example of why you read the data instead of guessing. "Water leak detector" looks like a leak detection lead. It is someone shopping for a gadget.

Don't over-block

Our first draft of that list had "free" as a negative across the whole account. We pulled it before anything went live. It would also have blocked "free estimate plumber near me" and "free plumbing quote", which are people ready to hire. Block the tire-kicker phrase, not the word.

Set location to presence

In the location settings, choose people who are in or regularly in your service area. The default also shows ads to people who are only interested in the area, like someone three states away reading about it. At these click prices, that setting alone is worth checking today.

Read the search terms every week

The search terms report shows what people actually typed before they clicked. New junk shows up there first. A weekly pass that adds new negatives is the single most useful hour in a Google Ads account.

Most contractor work starts with a phone call, so call tracking is the base of everything else. Here is the setup we use, in the order we do it.

1. Add a call asset with call reporting on

Add your real business number as a call asset and turn on call reporting. Google shows its own forwarding number in the ad and passes the call to your line. It takes about five minutes, it is free, and nothing on your website or your Google Business Profile changes. Keep any tracking number off your Business Profile and your directory listings. Those should always show your real number.

2. Count only real calls as conversions

Set a minimum call length for a call to count. Google's default is 60 seconds. In our LSA call data, about a third of recorded calls ran under a minute (16.3% under 30 seconds and 17.0% from 30 to 59 seconds). The median was a little over two minutes. Short calls are hang-ups, wrong numbers and "do you do this?" If they count as conversions, Google learns to buy more of them.

3. Record from day one

Conversion data is not retroactive. Anything not recorded in the first week is gone. You don't need automated bidding on day one, but you need the tracking running. We usually start on manual or click-based bidding for the first couple of weeks and move to Smart Bidding once there is conversion history to learn from. Google says the Learning status lasts no more than 7 days after a change.

4. Match calls to jobs in your CRM

A conversion in Google Ads is a call, not a job. The only way to know your cost per booked job is to take each call's phone number and find it in your CRM, then see whether it turned into an invoice. We set this up inside the CRM the contractor already uses, whether that is ServiceTitan, Housecall Pro, JobNimbus or something else.

For Kinetic Electric in Rancho Cucamonga, matching leads to invoices in their CRM by phone number showed 8 jobs worth $33,265 invoiced in September 2026 from Google Local Services Ads and Yelp. That was LSA and Yelp, not Google Ads, but the method is the same. See the Kinetic Electric case study and our call tracking and CRM setup.

It also tells you whether the problem is the ads or the phone. Across our LSA accounts, leads that were answered for 30 seconds or more were marked booked 30.5% of the time. Leads that were not answered were marked booked 7.7% of the time. More clicks won't fix that gap.

Start from the click cost, not a round number. At LocaliQ's home and home improvement averages, $2,000 a month buys about 240 clicks and about 19 calls or forms. At the low end of the "plumber near me" range in the Inland Empire ($31.59), the same $2,000 buys about 63 clicks. At the high end ($90.00), about 22.

That math is why we fund fewer searches fully instead of many searches a little. A campaign that gets five clicks a day tells you something within a month. One that gets one click a day across 40 keywords tells you almost nothing. If the budget can't cover the click cost of your main search for a steady stream of calls, start with LSA and the planned-work searches, and add the expensive searches later.

When to turn it up

Raise the budget when cost per booked job holds steady and the crews have room. Paid search scales with spend, and the cost per job is what tells you whether it is still worth it. On the LSA side, TMC Roofing's spend went from $10,267 in August 2026 to $21,714 in September. Charged leads went from 102 to 202, and cost per booked lead held near $160 ($162.96, then $159.66). That is what a healthy scale-up looks like. If cost per job climbs fast as you raise spend, you have run out of good searches at that price.

Give it 90 days

We plan on about 90 days of steady spend and tracked calls before calling a Google Ads campaign a win or a loss. That is long enough to get past learning, clean up the search terms and match a few months of calls to jobs. It is our working target, not a Google rule.

Sometimes the right answer is to wait. We tell contractors to hold off when:

We run Google Ads inside an account you own, alongside Local Services Ads and your Google Business Profile. Urgent and planned work get separate campaigns. Negatives go in before launch. Every call is tracked and matched to jobs in your CRM, so we can report cost per booked job, not clicks.

We work with contractors doing $1M or more a year, starting at $5,000 a month. Terms are a 90-day minimum, then month to month, with a 90-day results guarantee.
