For a long time, publishers have known that too many tech vendors can cause headaches, slowing down page-load times and risking data leakage. Recent research shows just how bad it is.
Between August and November, ad tech consultancy Redbud scanned 68 of the top news and magazine sites in the U.K., Germany and France to assess the impact of third-party cookie synching — used to track people from one system to another — and other third-party trackers on publisher sites.
The study, commissioned by tech company ID5, found 81% of the sites had vendors identified as potentially causing privacy risks, either from a compliance or data-leakage perspective. It also found third-party redirects slowed sites an average of 19 seconds. Redbud also found that 58% of vendors registered with trade body the Interactive Advertising Bureau Transparency and Consent framework are not reading consent strings, which are used to ensure compliance with the General Data Protection Regulation.
“That was the most shocking stat of all,” said Adriana Tailor, head of data and insight at magazine publisher TI Media.
The report also found that 80% of sites visited had vendors dropping cookies that were not GDPR compliant. Reasons ranged from vendors simply not sharing privacy policies to not counting third-party cookies as personally identifiable data.
“Cookie matching has been a major part of the programmatic pipes that were laid down in 2008, the people who designed and built them just aren’t in the industry anymore,” said Mathieu Roche, co-founder and CEO of ID5.
“Publishers are carrying out audits and they want to clean up what’s going on,” said Chloe Grutchfield, co-founder of Redbud. “There’s a lot of willingness to take control and encourage vendors to make appropriate changes. [Publishers] are being proactive.”
