What the Brand Was Facing
ECU Flash is a UK automotive tuning and diagnostics specialist. They came to Arascow to expand their reach and grow qualified inquiries in a considered-purchase market where customers research for weeks before committing.
What We Did to Fix It
We segmented the account by service intent and layered in custom audiences of users engaging with tuning forums and performance-car content. We ran systematic ad-copy testing alongside landing-page improvements focused on load speed and Core Web Vitals, ensuring interest survived the click. We began bidding under manual control for high accuracy, then moved to conversion-based automation once the data matured.
What They Achieved With Us
From November 2024 to September 2025, the campaign generated 14.3K clicks, 1.88K conversions, a £1.71 average CPC, and a 13.16% conversion rate. This growth is evidence that disciplined structure compounds return in a high-consideration niche.
