How The Telegraph Is Building a Future Free From Third-Party Cookies - AdWeek | The Marteq Alert | Scoop.it
The Telegraph has been building up its first-party data trove since introducing its subscriber-first strategy in 2017. In October, it had 525,000 print and digital subscribers, plus 6.8 million registered users (who can access several articles a week in exchange for an email address), nearing its goal of 1 million subscribers and 10 million registrants by 2023.

With Unity, ad buyers can use their own first-party data pools to locate and match audiences. Using secure data clean rooms called bunkers from tech platform InfoSum, marketers can only target The Telegraph audience that overlaps with the marketers’ own databases. These types of second-party data deals have been gaining steam now that there are more reliable ways to guarantee against the leakage of valuable data.

Third-party cookies have a limited shelf life, and publishers like The Washington Post, Insider and Vice are exploring a future without them. Ad buyers can still target audiences using cookie-based identifiers, but they are becoming less effective as web browser makers increase opacity to protect user privacy.
