Most advice about builder marketing comes from agencies that work with builders alongside plumbers, dentists, and e-commerce stores. This doesn’t.
Sea Salt Marketing has worked exclusively with residential builders across Australia and New Zealand since 2015. More than 300 builder relationships. Every campaign we’ve ever run has been for a builder. That gives us something no generalist agency has: a decade of AU/NZ-specific data on what builder lead generation actually costs, what it produces, and what separates the builders who grow from the ones who stay stuck.

The Variable That Changes Everything: Time in Market
The single biggest driver of builder marketing performance isn’t spend level, platform choice, or creative quality. It’s time. Builders investing consistently for five or more years see fundamentally different results to those who are less than five years in.
Before the table: two lead types to understand. A Meta opt-in is someone who submits their details via a lead form ad – softer, higher volume, lower cost. A direct enquiry is someone who contacts you through your website – higher intent, higher cost. Both serve different stages of your funnel. The benchmarks below cover both.
| Metric | Investing 5+ Years | Less Than 5 Years |
| Meta opt-ins per month | 30 | 12 |
| Cost per opt-in lead (Meta) | $10 | $35 |
| Cost per direct enquiry (Google) | $150–$250 | $450–$500 |
| Impressions per month (per channel) | 50,000 | 27,000 |
| Link clicks per month (Meta) | 1,000 | 620 |
| Cost per click (Meta) | $6.80 | $17 |
| Min. monthly ad spend (Meta / Google) | $600 / $900 | $900 / $1,500 |

The gap between established and newer accounts isn’t marginal. On Meta opt-ins, established clients pay 3.5x less per lead and generate 2.5x the volume. When you extend this to overall campaign efficiency – reach, clicks, impressions – the compounding effect of consistent investment is clear. Audiences warm up. Creative improves. Google Quality Scores rise. You cannot compress five years of consistency into a three-month burst.
The Real Problem Isn’t Ads. It’s What Happens After the Lead.
The gap between our highest and lowest-performing clients rarely comes down to ad spend or platform. It comes down to nurture.
A residential builder’s sales cycle runs 12 to 22 months from first enquiry to signed contract. Most builders run ads, get a lead, call once, and move on if the person isn’t ready right now. That’s an enormous amount of marketing spend walking out the door.
The builders who consistently outperform on pipeline value do one thing differently: they stay in contact across the full decision journey. Email sequences, retargeting, consistent social presence. The person who enquired in March but wasn’t ready still hears from them in August. When they are ready, there’s no question about who they’re calling.
More ad spend without a nurture system is like filling a bucket with a hole in it.
What Consistency Actually Produces: Roda Developments
Roda Developments has been an SSM client since 2016. When we started, they were doing $2M in annual turnover. They’re now at $16M. Enquiries grew 6x. The calibre of those enquiries shifted. They stopped chasing work and started choosing clients.
That’s not purely a marketing outcome. Great builders build great businesses. But consistent, long-term marketing investment created the pipeline certainty that let them commit to growth. The data shows this pattern across our client base. The builder stories confirm it.
Three Things Builders Get Wrong
- Treating marketing as a tap to turn on when work slows down
You can’t compress five years of consistency into a three-month burst. The CPL gap in the benchmark data is the cost of stopping and starting.
- Measuring leads instead of measuring revenue
A $35 lead that converts to an $800,000 build is worth more than a $10 lead that never progresses. Track pipeline value and conversion rate, not just volume.
- Marketing only to people ready to build right now
With a 12 to 22 month decision window, most of your market isn’t ready today. The builders with the strongest pipelines are present throughout the whole journey, not just at the point of search.
