The Challenge: Ad Fraud Was Eating into ROAS
FIDIA Inc. is a fast-growing Japanese company operating across lifestyle, HR, advertising, and investment. Its advertising division runs performance-based campaigns for diverse industries — from e-commerce to financial services.
As the company scaled, it faced a growing issue: fraudulent clicks were inflating costs and eroding profitability.
Google Ads and Yahoo! Ads reported some “invalid clicks,” but FIDIA’s team suspected the real impact was far greater. Sudden traffic spikes, suspicious IP activity, and unexplained conversion gaps raised red flags. With limited resources, however, the team struggled to verify or block fraud effectively.
As one manager put it, “Every click mattered. We couldn’t afford to waste even a single one.”
The Solution: Spider AF Ad Fraud Protection
An affiliate partner recommended Spider AF, prompting FIDIA to try the free ad fraud diagnosis.
The results were sobering: far more fraudulent activity than expected, especially in high-CPC categories like financial products and online clinics. This aligned with Spider AF’s broader findings — in 2024, the financial industry recorded the highest ad fraud rate at 14.3%, nearly 3x higher than the average.
▼Results from the free diagnostic period:
FIDIA chose Spider AF for several key reasons:
- Real-time detection & blocking of fraudulent clicks
- Advanced logic to distinguish bots from legitimate users
- Proprietary fraud database preventing repeat attacks
- Refund claims enabled for invalid clicks on Yahoo! Ads
These capabilities gave the team confidence to tackle fraud head-on, ensuring ad spend was directed only toward real prospects.
The Results: ROAS Increased from 108% → 125%
Within one year of implementing Spider AF, FIDIA achieved:
- 15% ROAS improvement (108.2% → 124.7%)
- Significant reduction in wasted ad spend from fraudulent clicks
- Higher efficiency across financial product campaigns
- Confidence to expand into new platforms and verticals
Without protection, the company estimates its losses would have been far higher, especially when scaling campaigns to broader networks.
Future Outlook
Looking ahead, FIDIA is preparing to expand into:
- Video platforms (YouTube, TikTok Ads)
- Social channels (LINE, Meta)
- Affiliate models beyond traditional frameworks
As the company scales, ad fraud prevention remains a core pillar of marketing infrastructure, safeguarding ROAS and ensuring sustainable growth.
