Why is click fraud growing?
In 2026, automation tools, headless browsers, and datacenter IP rotation make click fraud scalable. On CPC campaigns, every fake click is direct budget loss.
Detection methods
- **Behavior analysis:** FAST_CLICK, NO_MOUSE_MOVEMENT, COORDINATE_REPEAT
- **Device fingerprint:** Canvas, WebGL, hardware profile
- **IP reputation:** Datacenter prefix lists (Azure, GCP, AWS, OVH)
- **gclid reconciliation:** Google Ads click_view vs local beacon
Google Ads side
DubixGuard automatically adds fraud IPs as **negative criteria**. LRU rotation applies at the 500 IP limit. Evidence-based refund reports are prepared for Invalid Click Investigation.
