Feature overview

Everything needed to separate real paid visitors from suspicious ad traffic.

Click Fraud Block combines paid-click detection, server-side blocking, bot scoring, range escalation and exportable evidence in one protection layer.

🎯

Paid traffic recognition

Detects advertising traffic through current Google Ads markers, rotating suffix versions, Sklik identifiers and UTM-based paid sources.

  • Google Ads suffix support
  • Sklik and Seznam paid markers
  • Legacy parameter awareness
🛡️

Server-side blocking

Suspicious requests are handled before the landing page logic needs to run. This reduces dependency on cookies, JavaScript and client-side analytics.

  • 404-style block response
  • Low overhead for normal visitors
  • Works before analytics fires
📈

Range escalation

Repeated abuse can escalate from individual IPs to smarter network ranges, including IPv4 /24 and IPv6 /64.

  • Range incident memory
  • Unique IP and active-day thresholds
  • Separate web and Ads-only behavior
🔍

Replay detection

Tracks repeated paid URL markers and suspicious identifier reuse, especially when the same ad URL is hit again and again.

  • Replay history
  • Rotating marker awareness
  • Paid-only evidence trail
🧬

Client hint fingerprinting

For paid traffic, the system can collect browser client hints and lightweight fingerprint signals to strengthen fraud analysis.

  • User-Agent comparison
  • Client hint hashing
  • Paid-only collection strategy
🏗️

Hosting network detection

Known hosting and datacenter ranges can be classified more aggressively than normal residential or mobile networks.

  • Static CIDR list
  • Datacenter reason tagging
  • Range-level prevention
🤖

Verified crawler handling

Google and Seznam infrastructure can be treated separately from human paid clicks to avoid false positives in replay statistics.

  • Google infrastructure recognition
  • SeznamBot handling
  • Crawler-safe pass logic
📊

Dashboard and API

Review blocks, passes, ranges, reasons and export status from a dashboard and a machine-readable blacklist API.

  • Range statistics
  • Reason codes
  • Google Ads export feed
🧾

Audit-ready logs

Paid click events are retained for investigation, evidence gathering and comparison against advertising platform data.

  • Individual IP records
  • URL and source samples
  • Longer audit retention
