The Challenge
Cairns Smoke Alarms wanted to generate consistent, high-quality leads through Google Ads while keeping cost per enquiry low. Like many service businesses, previous campaigns focused on traffic volume rather than conversion efficiency — leading to inconsistent lead quality and wasted ad spend.
Our goal was simple: build a predictable lead engine that converts visitors into enquiries at an exceptional rate.
Step 1 — Market Testing With Broad Campaigns
We began with a broad Google Ads campaign designed to learn, not optimise.
This phase allowed us to:
- Understand real search behaviour in the Cairns market
- Identify high-intent vs low-intent searches
- Gather conversion data quickly
- Discover which services and messaging resonated most with customers
Rather than guessing keywords, we let real user data guide decisions.
Step 2 — Data-Driven Keyword Refinement
Once sufficient data was collected, we progressively refined the campaign:
- Removed underperforming searches
- Eliminated low-intent traffic
- Transitioned toward exact match keywords
- Focused budget only on proven converting terms
This shifted the campaign from traffic acquisition → intent capture, ensuring ads were shown only to users actively looking for smoke alarm services.
Step 3 — Conversion Rate Optimisation (The Real Multiplier)
With high-intent traffic established, we turned attention to the website experience.
We continuously tested and optimised:
- Hero messaging and offer clarity
- Page structure and layout
- Call-to-action placement
- Trust signals and service explanations
- Mobile usability and speed
Each improvement compounded results — transforming the website into a dedicated lead-generation asset rather than just an information page.
The Results
The outcome was a tightly optimised system where ads and website work together:
- 25–30% conversion rate from Google Ads traffic
- 27% overall website conversion rate (all traffic sources)
- Cost per enquiry as low as $15
- Higher-quality leads
- Reduced wasted ad spend
- Predictable monthly enquiry volume
These numbers mean Cairns Smoke Alarms captures a significant percentage of high-intent searches while maintaining extremely efficient advertising costs.
Key Takeaway
High-performing Google Ads campaigns aren’t built by chasing clicks — they’re built by combining data-driven keyword strategy with relentless conversion optimisation.
Cairns Smoke Alarms is a clear example of what happens when traffic quality and website performance are optimised together.
