Ad Blocker Test – Check If Your Ad Blocker Works (adblock.turtlecute.org)

I'm not sure about this. I got 7% blocked but in reality I rarely see ads when browsing the web.

[dead]

100% thanks to NextDNS and AdGuard.

I got 0% (FF+ubo) but ubo says it blocked 102 items. Also I never see ads while browsing or watching videos. What do?

Using uBlock Origin and nuMatrix on Librewolf got me 98% - some cosmetic ads got through.

This is clearly broken, it shows "3 blocked" even as uBO is reporting 89 requests to 34 different domains blocked.

EDIT it's below the fold: "Some browser/blocker combinations may affect results. If uBlock Origin breaks the test, allow adblock.turtlecute.org."

I’m interested as to who this is testing.

I see double click coverage, Amazon coverage, and a tiny amount of Facebook, but missing a lot of large players in the adtech space. I don’t see Microsoft being explicitly called here.

Then from the large scale independent companies I see none of them on here? Shouldn’t you try Trade desk, Magnite, Applovin, Criteo, Xandr as well?

Then you would want to check vs data brokers as well; Experian, Equifax, Axciom, Epsilon, LexisNexus, Liveramp, and CoreLogic at minimum.

The first time I opened the link I only got 17% blocked. I opened the link again and it went up to 74%. Weird

Stock Brave: 63% w/uBOL: 65%

or just remove adblock and accept that people are paid by the ads on the websites you're reading

The methodology for validation seems a bit off, in my setup I return a local IP for all of the domains in that list and serve empty content for it. Thus it detects the ads getting through, but in reality they did not.

From Raymond Hill, the author of uBlock Origin:

  Please do not use those online tools which claim to measure how good is your content blocker, they are often flawed.[0]

I don't know how much that applies to this particular tool, but I did notice that it's flagging requests as 'not blocked' even though they're blocked with uMatrix.
