We won’t bore you with complaints here though; hopefully you’ve now got enough information to understand what’s going on in the background when you sign up to use our free adblock measurement service.
From the homepage: Measure:
How many of your visitors are blocking ads and how much does it cost you in advertising revenue?
It does cost you if the ad revenue is supposed to cover your bandwidth costs. If you're hosting something heavy and users don't offset it by clicking the ads every once in a while, it's a problem. Also there are plugins out there which will load the ad content, but never display it - that means if you pay to advertise somewhere, you just paid for nothing (service was provided, but noone saw the ad).
Having ads that nobody likes and ads that nobody sees pays the same.
The case where you need to know if ads are being blocked or not is when you're trying to determine if you should change the ads or find another way to monetize the site.
PageFair lets publishers reach out to adblock users: to explain why ad revenue is necessary to keep the site running, and ask them to support the site by whitelisting it so ads appear or by making a donation towards the running costs.
