Case Study: Europcar achieves 824% ROI & €19,300 monthly ad savings with Lunio

Europcar Saves Ad Spend & Time With Lunio

Europcar, the multinational car rental group, engaged Lunio after concerns raised by their digital agency about potential ad fraud across SEM channels. Unsure if fraud was affecting performance, Europcar sought an easy-to-use solution to detect and quantify any wasted ad spend; Lunio was brought in to investigate and offer automated click fraud protection.

Lunio implemented its automated, machine learning‑driven click fraud prevention (PPC Protect), onboarding all Europcar brands in a 15‑minute setup and requiring under two hours of combined team time in month one. Lunio’s solution detected €19,300 of fraudulent activity, drove a 14.4% uplift in traffic quality and delivered an 824% ROI in the first month, while allowing Europcar’s paid search team to carry on day‑to‑day work without ongoing monitoring.
