What’s next following Google’s User ID announcement?

Posted on: Monday 15 March 2021 | IAB UK

A round-up of key articles and events that will help our members to understand the implications of Google’s news and share their views with the industry

Article correct as of 22 March 2021.

Following Google’s announcement that it will not support alternate identifiers once third-party cookies have been phased out, we held a User ID Forum for our ad tech members to openly discuss the news and raise key questions. This has helped us to further understand the concerns that exist within the ad tech community and shape our next steps. 

Here is a current summary of key articles, events and meetings that will help our members to understand the implications of Google’s news and share their views with the industry:

Past events 

  • IAB Europe’s Town Hall with Google Ads: This took place on Tuesday, 16 March and allowed IAB UK members to hear first-hand from Google on the potential implications for advertisers, agencies, ad tech intermediaries, and publishers. 

  • Joint session with ISBA: At the end of March, we will be holding a session with ISBA to ensure that brands are hearing directly from the ad tech community. We held a meeting on 17 March for members to put views forward ahead of the session. 


If you have any questions - for either us at IAB UK or directly for Google - please don’t hesitate to get in touch. While we’re aware that there is currently a lot of uncertainty about what Google’s news will mean in practice, it’s crucial that we continue to engage in cross-industry dialogue and fully understand the implications for all areas of the digital advertising industry.
