GDPR ate the cookies on the news websites in Europe

The number of third-party cookies on European news sites has dropped by 22% since the introduction of the EU General Data Protection Regulation (GDPR), according to an Reuters Institute for the Study of Journalism (RISJ) study published this month.



The study of RISJ reveals significant shifts in the use of third-party content and cookies on over 200 news sites studied in April and July – before and after the introduction of GDPR – across seven EU countries: Finland, France, Germany, Italy, Poland, Spain, and the UK.

UK news sites, which had the most cookies per page in April, had 45% fewer by July; German news sites exhibited the smallest change with 6% fewer cookies in July than in April.
