Adblock Test: Check If Your Ad Blocker Works
Run a free ad blocker test to check whether your browser extension, VPN, DNS filter, or built-in blocker stops ads, trackers, analytics scripts, social tracking, and known ad domains.
Works with browser extensions, VPN ad blockers, private DNS, router filters, and built-in browser protection.

Diagnostic report
Protection breakdown
How to read it
Blocked means the request failed or was intercepted. Reachable means the host or probe looked reachable from this browser.
Remember
A perfect score here is a strong signal, but real-world blocking still depends on filter lists, apps, VPN settings, and DNS rules.

Test coverage
What does this adblock test check?
Super Adblock Test checks whether common ad networks, analytics scripts, tracker domains, social tracking hosts, error trackers, vendor tracking domains, and DNS-level ad domains are blocked in your current browser and network setup.
Ad network blocking
Checks whether known advertising domains and ad scripts are blocked before they can load.
Tracker blocking
Tests tracking and analytics domains used to measure visits, behavior, conversions, and cross-site activity.
DNS adblock test
Helps identify whether a VPN, private DNS, or router-level filter is blocking requests before they reach the browser. Learn how to test DNS blocking.
Browser extension test
Checks the protection currently active in this browser without assuming which extension or built-in feature performed the block. Learn how to verify protection.
Score guide
How to read your adblock test results
Blocked means the request failed, was intercepted, or could not reach the test domain. Reachable or unblocked means the domain appeared accessible from this browser and network.
A high score is a strong signal, but not a guarantee that every ad online will be blocked. Real-world protection depends on filter lists, DNS rules, browser settings, VPN settings, and app-level protection.

How to improve your adblock test score
If your score is low, your blocker may be disabled, missing privacy filter lists, allowing acceptable ads, or only blocking ads inside one browser instead of across your whole device. Use the adblock troubleshooting guide for deeper checks.
- 1
Check that your ad blocker extension is enabled in this browser.
- 2
Turn off “acceptable ads” or “allow non-intrusive ads” if your blocker has that option.
- 3
Enable privacy and tracking filter lists such as EasyPrivacy or your blocker’s tracking protection list.
- 4
Use a DNS-level or VPN ad blocker when you need supported protection outside one browser.
- 5
Run the test again after clearing cache or opening a private window.
Honest limits
What this test can and cannot prove
The headline Protection Score is a weighted summary of the tested modules. The Raw Block Rate shows the direct blocked-versus-total result. Neither guarantees that every ad, sponsored post, first-party ad, native ad, YouTube ad, or anti-adblock script will be blocked. Some sites serve ads from the same domain as their content, and blockers can behave differently in normal windows, private windows, mobile browsers, and apps. Treat the result as a practical signal, not a full privacy audit.

Adblock test FAQs
How do I test if my ad blocker is working?
Select Start test and wait for every probe to finish. Blocked results show that the tested request was stopped by your browser extension, built-in protection, VPN, or DNS filter. Reachable results identify requests your current setup allowed.
Why is my ad blocker not blocking everything?
Your blocker may be disabled, allow acceptable ads, use limited filter lists, or protect only one browser. First-party ads, native placements, and sponsored content can also be delivered differently from known third-party ad domains.
Can this test check DNS ad blocking?
Yes. The test can show whether known ad and tracker hosts are unreachable through private DNS, a router-level filter, or a VPN. It cannot identify which protection layer performed the block.
Does a 100% adblock test score mean every ad is blocked?
No. The headline Protection Score is a weighted module summary; use the Raw Block Rate for the direct blocked-versus-total result. First-party ads, native ads, sponsored posts, video ads, and new or site-specific delivery methods may still appear.
Why do different ad blockers get different scores?
Tools use different filter lists, update schedules, default settings, and blocking methods. Your browser, enabled privacy lists, custom rules, VPN, and DNS provider can all change the combined result.
Can this test check browser, VPN, and DNS-level ad blocking?
Yes. Enable your chosen protection and run the test. The score reflects the combined filtering of this browser, VPN, private DNS, and network, so it cannot always attribute a block to one specific layer.
Why are trackers and analytics tested separately from ads?
Some blockers stop visible advertising but allow measurement or social tracking requests. Separate categories reveal which kinds of requests your setup blocks instead of hiding them inside one total.
Should I test in a private window too?
Yes, if you use private browsing regularly. Extensions may need separate permission to run there, while browser protections and cookie behavior can also differ from a normal window.
