web beacon/tracker blocking


i’ve had a good scour of the web, but i cant find anything concrete on the subject.

Does anyone know how prevalent tracker/beacon blocking is.

That is to say, what percentage of internet users are actively blocking (through browser plugins or hosts files trickery etc) tracking tags / web beacons.

Many thanks,


I would guess that this metric is hard to pin down because detecting a client-side blocking plugin probably requires some kind of third-party tracking pixel to do the reporting.

True, i’m guessing its higher than we currently understand, my initial investigations would suggest its as high as 10% of visitors are actively blocking tracking tags (through comparing server logs, tea-leaf and tracking beacon results for 2 domains).
