Analytics page impressions - Adsense page impressions = browsers with

How many browsers are using adblockers?

I was nutting out my stats and figured that the difference between the Analytics and Adsense page impressions must be the number of users using adblocking software. I used the last 4 weeks stats and found for me that means that 22% of visitors use adblocking.

Thats getting pretty sizable. In the future we should be able to track the changes easier with the integration between adsense and analytics.

edit: sorry about the truncated title. meant to be "Browsers with adblocking"

Stats will pretty much always differ between different tools. Firefox has an ever increasing number of users and the noscript addon is one of the most downloaded so I always expect differences.

FF accounts for 24% of my users and the stats differ around 8% so for me I know a fair chunk of users are using JS blocking tools.
