CentriWebGoogle Ads for builders is worth it when people in your area are actively searching for the kind of homes you build, your ads only show for those searches, and someone answers every enquiry quickly. It isn’t worth it when clicks land on a generic homepage, calls go unanswered, or you judge the results by clicks instead of signed jobs. Start small, keep it tight and measure it properly.
This guide covers when search ads make sense for a residential builder, what to bid on and what to exclude, where to send people, how to track calls and forms, and how to work out whether the spend is paying off. It’s based on Google’s own help pages, so you can check the detail yourself.
When does Google Ads for builders make sense?
Search ads show when someone types something into Google. That’s their strength: you’re reaching people who are already looking, not trying to interrupt them. A search like “knockdown rebuild builder” plus a suburb tells you a lot about what that person wants.
Ads tend to make sense when:
- there are real searches for what you build in the areas you build in
- you have capacity for more work in the next six to twelve months
- your website clearly shows what you build, where, and roughly what it costs
- someone can answer the phone or reply to a form the same day
They make less sense when your books are full, when you build in a very small area with few searches, or when nobody has time to follow up. In that last case, fix the follow-up first. Ads only buy you the enquiry. You still have to win the job.
If you haven’t yet looked at where builders’ enquiries come from, start there. Ads are one channel among several, and often not the cheapest.
What should a builder bid on?
Keywords are the searches you’re willing to pay for. Google’s help page on keyword matching options explains the three match types:
- Broad match (no symbols): your ad can show for related searches, including ones that don’t contain your words. It reaches the most people and gives you the least control.
- Phrase match (in quotes, like “home builder”): your ad can show for searches that include the meaning of your keyword, including more specific versions.
- Exact match (in square brackets, like [custom home builder]): your ad shows for searches with the same meaning or intent. It gives the most control and the smallest reach.
Google says it’s critical to use Smart Bidding with broad match, because the bidding needs signals to decide which searches are worth paying for. If you’re starting with a small budget and little tracking data, phrase and exact match give you more say over where the money goes.
Build ad groups around what you actually do: new homes, knockdown rebuilds, dual occupancy, custom homes, and the suburbs or regions you build in. Keep each group’s keywords, ad and landing page talking about the same thing.
Which searches should you exclude?
Negative keywords stop your ads showing for searches you don’t want. Google’s negative keywords help page notes that negatives don’t automatically match close variants, synonyms or plurals, so you need to add those yourself.
A starting list for most residential builders:
| Exclude | Why |
|---|---|
| jobs, careers, apprentice, salary, employment | People looking for work, not a builder |
| course, licence, training, how to become | People studying to be a builder |
| DIY, kit, owner builder | People planning to build it themselves |
| free, cheap, template | People looking for free plans or bargains |
| Services you don’t offer, such as granny flat, renovation or commercial | Work you’d turn down anyway |
Check the search terms report every week for the first couple of months. It shows the actual searches that triggered your ads, and it’s where you’ll find the next words to exclude. Google also notes that too many negatives can cut your reach, so don’t exclude words you’d actually want.
Where should the ad send people?
Sending ad clicks to your homepage is an easy way to waste a budget. Someone who searched for a knockdown rebuild should land on a page about knockdown rebuilds, in their area, with a clear next step.
A good landing page for a builder has:
- a headline that matches the search and the ad
- the areas you build in
- photos of homes you’ve actually built
- a rough idea of price or what affects it
- your licence details and how to check them
- a short form and a phone number that someone answers
The form can ask a few useful questions, such as whether they have land, their timing and their rough budget. Our guide on qualifying new home enquiries has the questions that matter.
Check your state’s advertising rules too. In Queensland, the QBCC’s advertising page says licensees must show the name they’re licensed under and their licence number, and it lists websites and social media pages as advertising. Other states have their own rules, so check with your regulator. This is general information, not legal advice.
How do you track calls and forms?
Without tracking, you can’t tell which searches turn into enquiries, and Google’s bidding can’t learn either. Plenty of homeowners still pick up the phone, so track calls as well as forms.
- Calls from the ad itself. Google’s help page on phone call conversion tracking covers calls made straight from your ad.
- Calls from your website. Google can show a forwarding number on your site to people who came from an ad, so it knows which ad led to the call. Its setup page explains that a call only counts once it lasts longer than a minimum length you set. That filters out wrong numbers.
- Form submissions. Count a completed enquiry form, not a visit to the contact page.
- What happened next. Google Ads can take in qualified and converted leads from your own records, so the system learns which enquiries turned into real prospects and signed work, not just which ones filled in a form.
How much should a builder spend on Google Ads?
It depends, and anyone who gives you a fixed number without looking at your area is guessing. What you pay per click depends on how many other businesses are bidding on the same searches in your market. That varies a lot from one area to the next.
A sensible way to set a first budget:
- pick a monthly amount you could spend for three months without a single signed job and still be fine
- run only your best-fit services in your core suburbs
- set the daily budget so it lasts the whole month
- review it monthly against enquiries, not clicks
Only increase spend once you can see enquiries that look like real jobs. Doubling a budget doesn’t fix a campaign that’s sending the wrong people.
Measuring by signed jobs, not clicks
Clicks and click-through rates are easy to find in the Google Ads dashboard. On their own, they tell a builder very little. What matters is what each signed job cost you.
Every quarter, look at four figures for your ads: what you spent, how many enquiries came in, how many were a real fit, and how many became signed contracts. A new home can take many months from first enquiry to contract, so record where every enquiry came from when it arrives, and keep that record with the job all the way to a contract or a clear no.
If ads bring enquiries but few become jobs, look at the whole chain before blaming the ads: the searches you’re paying for, the landing page, how fast you replied, and how the first conversation went.
Where to start
- Make sure every enquiry gets a reply the same day.
- Build one landing page for your main type of home, in your core suburbs.
- Set up call and form tracking before the ads go live.
- Start with phrase and exact match keywords and a solid negative list.
- Check the search terms report weekly for the first two months.
- Judge it after a quarter by enquiries that fit and contracts signed.
Ads are one part of the job. Turning those enquiries into signed homes is the other.
