The challenge

Charco Neurotech makes the CUE1, a device that helps people living with Parkinson’s. It is a considered, high-value purchase in a category where every ad platform restricts targeting heavily. The question was never whether ads could generate clicks — it was whether paid search could return meaningfully more revenue than it consumed, consistently enough to scale behind.

Our approach

We built the account around tracked revenue rather than conversion counts. Brand, condition-led and lead-generation intent were separated into distinct campaigns so each could be judged on the revenue it returned rather than the volume it produced. Bidding moved onto value-based targets, and budget was concentrated on the campaigns proving they could turn spend into sales instead of into traffic.

The outcome

Paid search returned 8.1× on every pound spent, generating over £77,000 in tracked revenue. Each conversion cost roughly £18 while carrying an average value near £146 — a margin wide enough to keep scaling into. The account now behaves as a revenue channel rather than an awareness cost, which is what makes it worth funding.
