Read Full ReviewFAQ: Choosing a Click Fraud Tool
-
Consider your ad spend, integration needs (Google Ads, Bing, etc.), and whether you need real-time blocking vs. post-click analysis. Tools like ClickPatrol and ClickCease offer strong all-around performance; budget-conscious advertisers may prefer Fraud Blocker, Clixtell, or Lunio.
-
Google filters some invalid traffic automatically, but industry data suggests 15–25% of clicks may still be fraudulent. A dedicated tool provides an extra layer of protection, automated refund requests, and visibility into traffic quality that Google doesn't always surface.
-
Detection identifies invalid clicks after they occur; blocking prevents them in real time by excluding known bad IPs and devices before they can click. Most modern tools do both—detect fraud for refund requests and block repeat offenders to reduce future waste.
-
Accuracy varies by tool and depends on the sophistication of their algorithms, data sources, and how they handle edge cases. We test each tool against the same criteria and rate detection accuracy separately. ClickPatrol and ClickCease consistently score highest in our tests.
-
Ad fraud is a $100B+ problem, which has attracted many solution providers. However, quality varies widely. Some tools offer enterprise-grade AI detection (CHEQ, ClickPatrol), while others provide basic IP blocking. Our comparison helps you cut through the noise and find the right fit for your budget and needs.
