The Story

Shelly (Hardware) is a reseller operating across DE, IT, FR, and ES who wanted to increase sales on the main products in their portfolio without overspending. Their main goal was simple: better ROAS with a setup that could scale across multiple marketplaces.

We worked with them on a managed AdFixer engagement and built a proper campaign structure tailored to their catalog and markets. The focus was on scaling sales responsibly: pushing volume where performance was strong, tightening targeting where spend wasn’t efficient, and continuously optimizing to keep growth profitable.

From 01 Sep – 31 Oct 2025, the account generated €326,982.88 in ad-attributed sales on €13,991.73 spend, holding ACoS at just 4.28% which equals a 23.37× ROAS. Since the “before” baseline was effectively 0 (no prior comparable ads data), this period represents a clean, profitable scale-up from launch.
