Construction marketing for an Australian builder comes down to three things: be in front of the build type people are actually searching for, publish the proof a nervous buyer checks before they call, and ask enough questions in your enquiry form to know which leads are worth quoting. On 24 September 2026 we audited 249 Australian builder websites and pulled a year of search data for ten build types to see how builders are doing on each of those three.
Most builder websites have a gallery, a phone number and some testimonials, and little else a buyer or an AI assistant can check. The builders that ChatGPT, Gemini, Perplexity and Claude named in our study were far more likely to list awards and publish a starting price.
Key findings
- Searches for “granny flat builders” averaged 2,450 a month from September 2025 to August 2026, up 147% on the year before, while “home builders” fell 20% and “renovation builders” fell 47%.
- September 2025 was the busiest month of the year for 16 of the 19 builder search terms we tracked. December and June to August were the quietest.
- Only half of the 96 builder sites we sampled from Google showed a licence number on the homepage, about or contact page. In Sydney, where the law says ads must carry it, 11 of 25 did.
- Builders named by AI assistants were more likely than unnamed rivals to mention awards (63% vs 40%) and to publish a price or “from $” figure (48% vs 29%).
- Only 6 of the 65 enquiry forms we could read were multi-step, and just 25% asked about budget.
This guide covers where builder demand actually is, what the best builder websites publish, and a channel-by-channel plan with links to our deeper guides. If you would rather have the whole system built for you, that is what our marketing for builders and construction companies service does.
Where builder demand actually is in 2026
Before you spend a dollar on construction company marketing, it helps to know how many people are looking for what you build. We pulled Australian Google search volume for the main build types, month by month, for the 12 months from September 2025 to August 2026 and compared them with the 12 months before.
Three things stand out. First, the biggest searches are not “builder” searches at all. House and land packages (11,183 a month on average) and display homes (6,542) dwarf every build-type term, which suggests many new-home buyers start with a package or a display village rather than a builder’s name. If you have display homes or packages, they deserve their own pages and their own ad groups.
Second, granny flats are the one build type clearly growing. “Granny flat builders” averaged 2,450 searches a month, up 147% on the year before, and the singular “granny flat builder” went from 480 searches in January 2025 to 2,900 in January 2026. Duplex builders also rose 20%. The broad terms went the other way: “home builders” fell 20%, “home extensions” fell 36% and “renovation builders” fell 47%.
Third, the city picture is not what most people expect. “Home builders perth” is the largest city builder search in the country, averaging 3,150 searches a month against 2,042 for Melbourne, 1,950 for Brisbane, 1,750 for Adelaide and 1,295 for Sydney. For custom work, Melbourne leads with 1,592 a month for “custom home builders melbourne”, ahead of Adelaide (986) and Sydney (887).
| Search term | Avg monthly searches | Change on prior 12 months | Busiest month | Quietest month | Suggested bid (US$) |
|---|---|---|---|---|---|
| house and land packages | 11,183 | +4% | Sep 2025 (14,800) | Jun 2026 (8,100) | 3.92 |
| display home | 6,542 | -36% | Sep 2025 (9,900) | Dec 2025 (4,400) | 2.15 |
| builders near me | 6,075 | -19% | Sep 2025 (8,100) | Dec 2025 (3,600) | 7.56 |
| home builders | 5,200 | -20% | Sep 2025 (8,100) | Jul 2026 (3,600) | 6.32 |
| granny flat builders | 2,450 | +147% | Jan 2026 (4,400) | Jul 2026 (1,000) | 9.29 |
| custom home builders | 1,992 | -20% | Sep 2025 (4,400) | Jul 2026 (1,000) | 8.19 |
| knock down rebuild | 1,193 | -6% | Sep 2025 (2,900) | Dec 2025 (880) | 8.52 |
| duplex builders | 888 | +20% | Jan 2026 (1,600) | Jul 2026 (390) | 5.48 |
| renovation builders | 835 | -47% | Sep 2025 (1,900) | Dec 2025 (480) | 14.08 |
| home extensions | 739 | -36% | Sep 2025 (1,900) | Dec 2025 (480) | 14.85 |
The bid column matters as much as the volume. Renovation and extension clicks carry roughly twice the suggested bid of “home builders” clicks, which is why a renovation builder with a weak landing page burns money faster than a volume builder does.
When builder demand peaks
September 2025 was the single busiest month for 16 of the 19 builder terms we tracked, including every city “home builders” search. The quiet stretches were December and the middle of 2026: “home builders sydney” dropped from 2,900 searches in September 2025 to 720 in June 2026, and “home builders perth” went from 6,600 to 1,600 by August. The exceptions were granny flats and duplexes, which peaked in January to March 2026.
The practical rule is simple. Build your SEO pages in the quiet months so they are ready before spring, and hold your ad budget back for the months when people are searching. Our guide to choosing between SEO and Google Ads for builders covers how to split the two around this calendar, and our Australian search seasonality study shows the same pattern across other industries.
What the best builder websites publish
To see what builders actually put in front of buyers, we took the top two builders from Google Maps and the top two builders from the organic results for 35 searches: seven build types (custom homes, knockdown rebuild, granny flats, duplexes, renovations, home builders and extensions) in Sydney, Melbourne, Brisbane, Perth and Adelaide. That gave 100 builder websites, of which 96 loaded properly. We read each homepage plus the about and contact pages where they were linked.
| What the site shows | Share of 96 builder sites |
|---|---|
| Click-to-call phone link on the homepage | 90% |
| Testimonials or a reviews section | 81% |
| Project gallery or portfolio | 77% |
| Video (embedded or self-hosted) | 61% |
| Founding year or years in business | 60% |
| HIA or Master Builders mentioned | 57% |
| Awards mentioned | 50% |
| Builder licence number | 50% |
| Display homes mentioned | 44% |
| LocalBusiness-type schema markup | 44% |
| Warranty or insurance mentioned | 42% |
| A price or “from $” figure | 41% |
| Service areas listed | 36% |
| Build time or timeline | 36% |
| Live reviews widget (Google or similar) | 23% |
| A stated review count | 16% |
The top of the table is the easy stuff. Almost everyone has a phone link, a gallery and a few testimonials. The bottom half is where buyers get stuck: fewer than half say what a build costs, how long it takes, which suburbs they build in or what warranty cover they carry. Those are exactly the questions people ask before they pick up the phone, and our guide to builder website design that converts goes through how to answer each one on the page.
The licence number gap
Half of the sites showed a builder licence or registration number anywhere on the homepage, about or contact page. The formats vary by state (DB-U or CDB-U in Victoria, a number ending in C in New South Wales, QBCC in Queensland, BC in Western Australia and BLD in South Australia), but the point is the same: a buyer who wants to check you on the register has to hunt for it.
In New South Wales this is more than a trust issue. The NSW Government’s guide to building trade advertisements says ads must show the licensee’s name and licence number, and it lists the internet as one of the media covered. Of the 25 builder sites we sampled from Sydney searches, 11 showed a licence number on the pages we checked. Some of the rest may show it deeper in the site, but a buyer looking at the homepage would not find it.
Enquiry forms that do not qualify anyone
We could read a real enquiry form on 65 of the 96 sites (the rest used embedded third-party forms, phone-only contact, or no form we could parse). The median form had 8 fields, but most of those fields were name, email, phone and a message box. Only 25% asked about budget, 15% about timing and 12% about whether the buyer owns land. Just 6 of the 65 were multi-step forms. That means most builders learn nothing about a lead until someone has spent time on the phone with them, which is the problem our builder service is built to fix.
What the builders AI assistants named do differently
In our shared study on 24 September 2026, we asked ChatGPT, Gemini, Perplexity, Claude and Google AI Mode for builder shortlists in six markets: custom homes in Melbourne, knockdown rebuilds in Sydney, granny flats in Brisbane, renovations in Perth, duplexes in Melbourne and home builders in Adelaide. We then took every builder the assistants named and every builder that appeared in Google’s Maps or organic top 20 for the same six searches, and compared their websites.
That gave 105 builder sites that at least one assistant named and 83 that ranked on Google in the same market but were not named by any of them.
The differences are about proof, not design. Named builders were more likely to mention awards (63% vs 40%), publish a price or “from $” figure (48% vs 29%), state a founding year or years in business (63% vs 48%) and mention Master Builders membership (38% vs 23%). Galleries made no difference at all (76% vs 77%), and LocalBusiness schema was slightly more common among the builders that were not named. Schema helps Google read your details, but it did not separate the two groups.
The assistants’ own search behaviour explains why. When ChatGPT built its shortlists, its background searches went to HIA or Master Builders award pages in four of the six builder prompts, and to state licence registers (NSW Fair Trading and the QBCC) in the other two. In Brisbane it searched the QBCC register for one builder’s licence number by name. An assistant can only find your award or your licence if you say it plainly somewhere it can read.
Two caveats. Big volume builders with large marketing teams are over-represented among the named builders, so some of the gap is about size, not tactics. And being named is not the same as being good: twice in our study an assistant recommended a builder brand that public records or review listings suggest may no longer be trading, so check any builder an AI names before relying on it. Our deeper guide on how AI decides which builders to recommend covers why assistants repeat old information and how to correct it.
Blocking GPTBot did not stop builders being named
Of the 249 builder sites that loaded, 49 (20%) either blocked OpenAI’s GPTBot in robots.txt or returned an error when we requested the homepage as GPTBot. Only 5 did it through robots.txt; the rest were server or hosting rules, most returning an unusual “418” error that points to a host-level bot filter. But 37 of those 49 served OpenAI’s separate search crawler, OAI-SearchBot, normally, and 22 of them were still named by an AI assistant in our study. OpenAI’s crawler documentation explains the difference: GPTBot collects training data, while OAI-SearchBot is what ChatGPT search uses. Check both before you worry, and check with your host if you did not set the rule yourself.
A construction marketing plan, channel by channel
Here is how we would build marketing for a construction company from scratch, in order. Each step links to a deeper guide.
1. Google Business Profile and reviews
Across the 35 searches, the top three Google Maps listings had a median of 41 reviews and a median rating of 4.9, and 21 of those 101 listings had fewer than 20 reviews. That is a low bar to clear. Ask every client at handover and again after the first month in the home, and ask them to mention the build type and suburb. Our guide to earning and using builder reviews has the scripts.
2. A page for every build type you want more of
If you build granny flats, duplexes and knockdown rebuilds, each needs its own page with its own photos, price range, timeline and form. One “services” page cannot rank for all three or answer all three sets of questions. Our SEO guide for builders covers page structure, suburbs and the People Also Ask questions worth answering.
3. Publish the proof buyers and AI assistants check
Put your licence number, association memberships, founding year, awards, warranty position and a starting price where a person or a machine can read them as text, not only in a logo or a PDF. This is the single cheapest fix in the whole audit. For the AI side specifically, our guide to AEO for builders explains what to publish and how to test it.
4. Google Ads by build type, timed to the calendar
Run separate campaigns for each build type, send each one to a matching page, and lean in from late winter into spring, when searches climb. Our guide to Google Ads for builders covers structure, geo-targeting and cost per qualified lead.
5. Meta ads for build types people do not search for yet
Some people do not think of a granny flat or a knockdown rebuild until they see one. Facebook and Instagram are where you create that demand with project videos and lead forms. Our guide to Facebook ads for builders covers creative, targeting and budgets.
6. Forms that qualify, and fast follow-up
Use a multi-step form that asks build type, suburb, land status, budget range and timing before contact details. Only 6 of the 65 forms we read did this. Then call back the same day. Our guide on getting building leads without buying them covers what to do with each lead once it arrives.
7. For custom builders: architects, awards and patience
Custom work has the longest decision cycle and the highest stakes, and it leans on referrals. Our KGN Homes case study shows how a Noble Park custom builder replaced a collapsed architect referral pipeline with lead magnets, custom landing pages and follow-up sequences. Our custom home builder marketing guide covers the rest.
Matching builder marketing to your build type
Not every build type should start with the same channel. This is how we would weigh them, based on the search data above.
| Build type | Search demand (monthly) | Where we would start | Why |
|---|---|---|---|
| House and land, display homes | 6,500 to 11,200 | Google Ads plus display home pages | High volume, cheap clicks, buyers already comparing packages |
| Granny flats | 2,450, growing | SEO pages plus Google Ads | Demand up 147% and peaks early in the year, so pages need to be live by January |
| Custom homes | 1,992 national | SEO, awards, referrals | Long decision cycle; buyers and AI assistants check awards and past work |
| Knockdown rebuild | 1,193 | SEO plus Meta ads | Steady searches, plus many owners who have not thought of it yet |
| Duplexes | 888 | SEO pages with feasibility content | Small, rising demand from investors who research before they call |
| Renovations and extensions | 739 to 835 | Tight Google Ads plus strong landing pages | Falling searches and the dearest clicks, so waste hurts most here |
How we did this research
On 24 September 2026 we ran 35 Google Maps and 35 Google organic searches (desktop, Australia, top 20) covering seven build types in five capital cities, and took the first two builders from each, which gave 100 builder websites (96 loaded). We added every builder named by ChatGPT, Gemini, Perplexity, Claude or Google AI Mode in the six builder prompts of our shared AI study (API versions with web search on, not the consumer apps), plus every other builder in Google’s top 20 for those six searches. In total we fetched 258 builder websites and 249 loaded.
For each site we read the homepage, rendered in a normal browser, plus the linked about and contact pages, and recorded the items in the tables above. We checked robots.txt and requested each homepage as GPTBot and OAI-SearchBot. Search volumes are Australian Google data for September 2025 to August 2026, compared with the 12 months before.
Limits: we read up to three pages per site, so details shown elsewhere were missed, and claims made only in images could not be read. Forms loaded through third-party embeds were not counted. Each AI prompt ran once, and answers vary between runs. The named group includes more large builders, so treat that comparison as a pattern, not proof of cause.
Frequently asked questions
How do you do marketing for a construction company?
Start with a complete Google Business Profile and steady reviews, then build one page per build type with photos, a price range, a timeline and a qualifying form. Add Google Ads by build type in the busy months and Meta ads for build types people need to see first. Publish your licence, awards and warranty as plain text.
When is the best time of year for builders to advertise?
In our data, September 2025 was the busiest month for 16 of 19 builder search terms, and December and June to August were the quietest. Granny flats and duplexes were the exception, peaking in January to March 2026. Build SEO pages in the quiet months and put more ad budget into late winter and spring.
Which build types are growing in Australia?
Granny flats were the clear growth area, with “granny flat builders” searches up 147% on the prior year to an average of 2,450 a month. Duplex builder searches rose 20%. Broad terms such as “home builders”, “home extensions” and “renovation builders” fell between 20% and 47% over the same period.
Should a builder show their licence number on their website?
Yes. It lets buyers check you on the state register in seconds, and AI assistants search those registers too. In New South Wales, the government’s building trade advertising rules require the licensee’s name and licence number in ads, including online. Only half of the builder sites we audited showed one on their main pages.
Does blocking GPTBot stop ChatGPT recommending my building company?
Not on its own. GPTBot is OpenAI’s training crawler, while ChatGPT search uses OAI-SearchBot. Of the 49 builder sites that turned GPTBot away in our test, 37 still served OAI-SearchBot and 22 were named by an AI assistant anyway. If your host blocks either one without your say-so, ask them to change it.
What is the difference between construction marketing and general trade marketing?
Builders sell bigger jobs with longer decisions, so the marketing has to carry more proof and do more qualifying. A plumber’s customer wants someone today, while a knockdown rebuild customer may research for a year. That is why build-type pages, published prices and multi-step forms matter more for builders.
Want a construction marketing plan built on your own numbers?
We can run this same audit on your website and your build types, show you where the demand is in your area, and build the pages, ads and qualifying forms that turn it into enquiries worth quoting. See how we work on our construction marketing services for builders page.
