About the report

In this sequel to the 2020 BT/PageFair Adblock Report, we present the latest data gathered for global adblocking and results from our U.S. consumer survey about adblock usage and privacy preferences. The increasing focus on user consent has been the driver of significant change in the advertising industry, from privacy regulations like GDPR and CCPA to Google’s looming deprecation of third-party cookies.

As we undertake this historical industry-wide pivot, one hypothesis we wanted to evaluate with the 2021 PageFair Adblock Report is whether user preferences about ads and privacy fall on a spectrum as opposed to being binary, as the industry and privacy advocates alike have presumed. In the Ads-Privacy Preference Matrix, we break out user preferences into nine distinct user buckets and estimate the percentage of US users that fall into each bucket based on their responses to our survey. We think this information will be invaluable both for publishers trying to better understand their audience and adtech companies building solutions for the market.

You’ll also find updated information on recurring themes from previous reports, such as the growth of desktop and mobile adblocking, region-wise penetration of adblocking, and a granular analysis of adblock countermeasures employed by the world’s leading publishers.
