For PPC advertisers, marketing teams, and agencies, Fraud Blocker helps identify invalid traffic that can waste ad budgets and produce low-quality leads. It monitors website visits in real time, scores traffic using more than 50 signals—including IP address, VPN or Tor use, device, and location—and can automatically send suspicious IP addresses to connected Google Ads and Facebook campaigns for blocking. Users can also export IP addresses for use with other ad platforms and adjust detection criteria such as location blocking. To get started, users add Fraud Blocker’s detection pixel to their website and connect their ad accounts. The service also checks email addresses submitted through lead forms, helping teams spot and block fake or spam leads. Visitor records can include details such as IP address, ad-click source, location, device, browser, and campaign tracking data, which can help advertisers review traffic quality and investigate suspicious activity.
