Shan Wang, Nieman Lab:
A prequel report from RISJ, released a few weeks before the General Data Protection Regulation came into effect May 25, found that some news sites researchers looked at were worse than popular non-news websites when it came to third-party content. These news sites averaged 40 different third-party domains per page and 81 third-party cookies per page, compared to an average of 10 and 12, respectively, for other popular non-news websites. (Researchers collected the data in the first three months of this year.)
This time around, researchers found declines in cookie prevalence on the 200-plus news sites they tracked, across several categories, from cookies related to advertising and marketing to ones related to design optimization (they looked at the difference between the sites in April and then the sites in July). On average, total cookies related to design optimization dropped 27 percent; cookies relating to advertising and marketing dropped 14 percent.
I’m not surprised by these findings. With GDPR warnings in place, collectors of lots of data can do one of two things: ask visitors for permission, or reconsider just how much data they need to collect. Conversely, without GDPR, it’s unlikely that data collectors would do either.
