Blocked

Blocked means the request was stopped or intercepted by your ad blocker, DNS filter, VPN or built-in browser protection.

Reachable

Reachable means the request went through. This category is not blocked in your current setup.

Honest limits

A perfect score is a strong signal, but no test can prove every ad will be blocked. First-party ads, native and sponsored placements, and new delivery methods can still appear. Blockers also behave differently across browsers, private windows and mobile apps. Treat the result as a practical signal, not a full privacy audit.
