Case Study: FIDIA boosts ROAS by 15% with Spider AF

How FIDIA Improved ROAS by 15% with Ad Fraud Prevention

FIDIA, a fast-growing Japanese company with performance marketing operations across lifestyle, HR, advertising, and investment, was seeing fraudulent clicks inflate costs and damage profitability as campaigns scaled. The team suspected the real impact was greater than the invalid clicks reported by ad platforms, but with limited resources, they struggled to verify and block fraud effectively.

FIDIA implemented Spider AF’s ad fraud protection after a free ad fraud diagnosis revealed significant fraudulent activity, especially in high-CPC verticals like financial products and online clinics. With Spider AF’s real-time detection and blocking, fraud logic, proprietary database, and Yahoo! Ads refund support, FIDIA improved ROAS from 108.2% to 124.7% within a year, a 15% increase, while reducing wasted spend and strengthening campaign efficiency.
