In a move that has the industry buzzing (again!) about how we use data to build personalised ads, Google has announced that “once third-party cookies are phased out, we will not build alternate identifiers to track individuals as they browse across the web<\/a>, nor will we use them in our products.” Essentially, Google will stop selling ads based on an individual user’s browsing habits across the web. Advertisers that rely on this data will need to find other means to target users.<\/p>\n

It feels like a milestone moment. But what, exactly, does this announcement mean in an industry where we continue to see a shift in protecting user privacy while many marketers and regulators start to phase out other data collection processes? Let’s take a closer look.<\/p>\n

Kiss third-party cookies goodbye<\/h2>\n

Last year, Google revealed plans to further protect user privacy on the web by making it easier for users to block or clear cookies used in third-party contexts. This new level of ad transparency will provide users with more visibility into the type of data that is being used, which will impact the way marketers can leverage data to personalise ads. We shared our thoughts on digital advertising in a cookie-less future<\/a> at the time.<\/p>\n

The use of third-party cookies has always been an integral tool for advertisers to deliver targeted, personalised ads. However, there have been growing concerns about privacy, with many users unaware of the data being collected on them while they browse online, which could range from email address harvesting to targeting you based on your political affiliation.<\/p>\n

As a result, Google is moving further towards a privacy-first approach to preserve anonymity. They will now choose to “hide individuals within large crowds of people with common interests” through their privacy-preserving technologies such as the Federated Learning of Cohorts (FLoC)<\/strong>. With FLoC, Google will group users into various audiences or cohorts based on similar browsing habits across the web, which effectively hides users “in the crowd” while using on-device processing to keep a user’s web history private. This would result in advertisers targeting ads to audiences and cohorts as opposed to an individual user, as shown in the below example:<\/p>\n

Despite their continued actions aimed at protecting user data, this only affects cross-site\/cross-domain tracking and will not affect advertising on Google’s own properties and services. Why? Because third-party cookies are not required to track user behaviour within a wholly owned entity such as Google, despite its many platforms (Search, YouTube, Gmail, etc.). As a result, advertisers will need to rethink their measurement solutions and be fluid with the changes in tracking data.<\/p>\n

    First-party data \ufe0f<\/h3>\n

    First-party data will continue to be the gold standard for targeting as third-party data becomes subject to tightened privacy and increased government scrutiny. First-party relationships will become vital and should be a top priority for all advertisers as there is minimal disruption to cookies in first-party contexts.<\/li>\n
