Fixing a Fire Safety Brand's Google Ads From the Ground Up
Mistek's ads were generating leads. They just cost twice as much as they should have.

The brief
Mistek are a multi-award-winning national fire safety specialist and one of the leading accredited installers of the Automist® water mist fire suppression system, a modern alternative to traditional sprinklers. Having managed Google Ads in-house, they approached us in 2024 for a reliable, expert-led route to profitable scale.
The challenge
The account was generating leads but lacked consistency and headroom to grow. Our audit found a significant share of budget being absorbed by broad, low-intent search terms and overlapping keyword targeting, inflating cost per lead and limiting impression share on the searches that actually mattered. Most traffic was also landing on the homepage, despite clear evidence that the "Get a Quote" page converted far better. The demand was there. The account simply wasn't built to capture it efficiently.
What we did
We rebuilt the campaign architecture from the ground up around efficiency and intent, introducing clearer bidding controls and continuously refining keyword coverage to concentrate spend on the searches most likely to convert. Ad copy and landing page alignment were improved to strengthen relevance, lifting Quality Scores and bringing costs down. Over the following 18 months we kept optimising, holding performance steady as it scaled rather than letting it drift.
