How does it work?

We check the ability to connect to popular advertising and analytics services. If your blocker works, requests will be blocked.

  • Domain check — attempt to load a resource from an ad server
  • Fingerprint check — canvas, WebGL, audio fingerprinting protection
  • WebRTC check — IP address leak detection
  • Element check — hiding ad blocks on the page
Important

A 100% result does not guarantee complete protection. The test checks a limited list of popular domains.

Frequently asked questions

How do I check whether my ad blocker works?

Run the test on this page: it tries to load advertising and tracking elements. Blocked ones mean your ad blocker is working.

What does the ad test show?

How many advertising and tracking requests were blocked versus allowed — that is, your ad blocker's real effectiveness.

Why is some advertising not blocked?

Some formats (native ads, anti-adblock workarounds) get through. Up-to-date filter lists and extra rules help.

Why test the ad blocker when using a proxy and anti-detect?

So ads and trackers do not break your environment isolation or expose multi-account work when using a proxy.
