Webinar Recap: Demystifying Third-Party Cookies: What Cookie Deprecation Means for B2B Media Companies

Episode 2 of Leverage Lab’s webinar series, The Growth Lab, dropped last week!   Industry experts AnnMarie Wills and John French delved into the intricacies of third-party cookies, first party cookies and new opportunities for media companies.

The threatened (or promised, depending on your outlook) deprecation of third party cookies is soon to be fully baked – that is, finally a reality.  But it’s far from the end for media companies – in fact, it’s a chance for you to stand in your power because of your rich first party data.

Here is a summary of the webinar’s key points:

Key takeaways:

  • Third-party cookie deprecation is happening now: It’s not a future threat, only 30% of web traffic is targetable with third-party cookies currently.
  • First-party data is the key to success: data collected directly from users is becoming more important for marketers. B2B media companies have a wealth of first-party data that they can use to target their audiences. Leverage your existing data on your audience and their interactions to understand them better and connect with them more effectively.
  • Invest in data infrastructure: Break down data silos and create a system that allows you to easily access and analyze your first-party data.
  • Embrace transparency: Be open with your audience about how you use their data and showcase the value you provide.  And be transparent with your advertisers, too!
  • Support your sales team: Equip them with the knowledge and tools they need to effectively communicate the value of your first-party data solutions to advertisers.



  • Many marketers are unprepared: Only 8% of marketers report being fully prepared for a post-cookie world.
  • Programmatic advertising needs to adapt: While programmatic can still be used as infrastructure, publishers need to find new ways to sell their inventory in this environment.
  • Replacing third-party data sources: Publishers need to find alternative ways to gather audience data beyond third-party sources.



  • Strengthen relationships with advertisers: By offering first-party data solutions, you can build stronger relationships with advertisers who are struggling to adapt to the changing landscape.
  • Differentiate yourself from competitors: By embracing first-party data and transparency, you can stand out from competitors who are still relying on outdated methods.
  • Gain deeper audience insights: By analyzing your first-party data, you can gain a deeper understanding of your audience and create more targeted and effective content and advertising campaigns.


Don’t wait until 3PD cookies are really gone to start preparing for a post-cookie world. Start investing in first-party data now.
