A commercial builder launching a new residential division signed $543,845.81 in revenue from $35,681.77 of Google Ads spend, a 15.2x return. KOA Digital built the campaign around a qualifying funnel and self-booking into the builder’s sales calendar, so the sales team spent its time with buyers who were ready to talk.
The client
The client is an established commercial builder that decided to move into residential work. We have kept the client anonymous, so this case study shares the numbers and the approach without identifying details.
Moving from commercial to residential is a big shift. The buyer changes from developers and project managers to homeowners, the sales conversation changes, and the business needs a steady flow of residential enquiries that its brand was not yet known for.
What KOA Digital did
We ran Google Ads to reach people actively searching for a builder. Instead of sending every click to a generic contact form, the ads led into a qualifying funnel. Prospects answered a few questions about their project before they could book, and those who were a good fit booked a time directly into the sales calendar.
That meant the builder’s team was not chasing every enquiry by phone. The appointments that landed in the calendar had already been through the qualifying questions.
The result
The campaign produced $543,845.81 in signed revenue from $35,681.77 of Google Ads spend. That is a 15.2x return on ad spend, measured on signed revenue rather than leads or clicks.
Why it worked
Three things made the difference. The ads targeted people with a clear intent to build. The qualifying funnel filtered out poor fit enquiries before they reached the sales team. And self-booking removed the delay between an enquiry and a conversation, which is where many builders lose good leads.
What this means for your building business
If you are a builder adding a new service or moving into a new market, the same approach applies: target buyers who are already searching, qualify them before they reach your team, and make it easy for the right ones to book.
