On each of your website's pageviews the PageFair analytics script reports whether or not ads were blocked on that page. On our servers we count the number of page views and pages where adblock was detected (to calculate your traffic adblocking rate) as well as the number of unique visitors and visitors who were blocking ads (to calculate your audience adblocking rate). We also record breakdowns by browser and country for our adblocking reports. We don't record any information about individual users.
