The story so far

Since Google announced that it would be phasing out all third-party cookies on Chrome by the start of 2022, the race has been on to find alternate solutions that both empower consumers and allow the ad-funded web to continue functioning. Google has now extended the cookie deadline to a three-month period in 2023 - giving the industry more time to prepare for the impending change - but with such a substantive shift in our ecosystem on the near horizon, how far have we come?

Member solutions

The deprecation of third-party cookies is the single biggest change that digital advertising has undergone since its inception, so it’s no surprise that there are a wealth of alternative solutions emerging.

Looking at the market overall, we can bucket these into three categories: user-enabled ID solutions, cohorts and contextual solutions. We’ve worked with our members to lay out the details of key solutions under development and help you understand what will work best for your business.
