Well… everyone! 

In this post, we’ll walk you through:


A Brief History of Cookies & Privacy

Within just the last three years, there have been numerous updates to strengthen the privacy of users on the internet:

  • May 2018: GDPR (European General Data Processing Regulation)
  • December 2019: CCPA (California Consumer Privacy Act)
  • March 2019: ITP2.1 (Apple’s Intelligent Tracking Prevention 2.1)
  • June 2019: ETP (Firefox’s Enhanced Tracking Prevention)
  • February 2020: SameSite (Google Chrome’s Security Update)
  • July 2020: LDU (Facebook’s Limited Data Use Feature)
  • November 2020: 7-Day Attribution Update (Facebook’s Move from 28-Day)
  • January 2021: Apple iOS14 (Opt In Privacy Prompt) 

More and more browsers are moving away from third-party cookies, with Google planning to deprecate them sometime in 2022.

First-Party vs. Third-Party Cookies

To understand this shift, you’ll have to know the difference between first-party and third-party cookies.

Why? Only third-party cookies are going away.

This puts an emphasis on the importance of first-party data once you lose the ability to track and target your audience via third-party cookies.

What are First-Party Cookies?

First-party cookies are created by the website you’re visiting.

This enables site owners to store user information to drive more personalized experiences for users. Some examples include:

  • Remembering what you added to your cart when shopping
  • Saved passwords
  • Content topics browsed

What are Third-Party Cookies?

Third-party cookies are created by websites other than the one you’re visiting.

The data providers who collect third-party data then enable other companies to purchase it to enrich their own datasets or better target specific audience segments. Some examples include:

  • Enabling remarketing
  • Enabling frequency capping to not spam a user
  • Tracking conversions
  • A/B testing
  • Ad fraud protection

Why is This Such a Big Deal for Marketers?

As a marketer, you rely on the ability to measure your online campaign performance and make changes to your efforts based on third-party data.

You’ve done this for YEARS.

What will you do when your CFO, CMO, or the Board asks about the ROI of your marketing efforts?

You may also rely on tactics like remarketing. Or you have ad fraud software to ensure you’re receiving quality traffic from your search and display campaigns. None of these would be possible without third-party cookies in our current state.

But alternatives are being explored to continue to respect user privacy while maintaining great user experiences…

How Companies like Google, Criteo, The Trade Desk, and Neustar are Adapting

Many companies are testing new ways to replace third-party cookies with a more anonymous way of tracking, yet still effective. The intention is to respect user privacy and continue to create great user experiences.

Federated Learning of Cohorts (FLoC)

Google is testing interest-based cohorts called FLoCs.

Google claims it still tracks 95% of the conversions when compared to cookie-based advertising, but this claim is still being debated as  Google hasn’t given much insight into their math.

Regardless, this would track groups of users rather than individual users. It ties into Google’s new browser framework called TURTLEDOVE, which would keep user data in the browser. A more recent proposal is FLEDGE, which incorporates the idea of an independent web server.

Unified ID 2.0

The Trade Desk, a demand side media buying platform, is leading the charge in developing Unified ID 2.0 (UID2.0).

UID2.0 is an open source framework that, in lieu of cookies, will leverage user’s anonymized email addresses. This is done via gaining consent by logging into a single specific website or app.

The Trade Desk also suggests that this approach is not only more privacy-first but that it’s also more operable between devices and platforms without increasing effort or frustration from the user.

Here’s a more in depth introduction to UID2.0 directly from the Trade Desk.   

Secure Private Advertising Remotely Run On Webserver (SPARROW)

Others, like Criteo, have similar proposals.

Criteo’s framework is called SPARROW which would still involve outside servers but it would be an independent third-party. This could keep user data more private and still enable features that could be lost completely with Google’s solution such as remarketing.

Neustar Fabrick™

Neustar launched Fabrick™. This isn’t necessarily a replacement for third-party cookies, but they’re developing ways using offline data to improve your targeting in a cookie-less world.

We believe most companies should be focusing on their own, first-party data in preparation for privacy-first advertising.

How You Can Adapt

While no one knows for sure exactly how these new solutions will play out, we know that things won’t stay the same as they are today.

At Seer, we like to use a Keep, Start, Stop framework for change management:

What should you KEEP doing? 

What should you START doing? 

What should you STOP doing?

Start Doing

  • Educate your managers and key stakeholders on the importance of this change and its anticipated impact. Get buy-in now vs. scrambling later.
  • Collect first-party data! You should be doing this already but if you’re not, there’s no time like the present!
  • Evaluate the benefits of server-side tagging, in this case, namely migrating a lot of 3P cookies to 1P cookies vs. the investment of migration, implementation, and maintenance 
  • Segment your customers — the future of targeting may only be as good as your own data. If you have all your customers lumped into the same segment, how will you personalize your targeting and messaging?
  • Keep up with the latest news around browsers & cookies

Keep Doing

Stop Doing

  • Relying on others to solve this for you. The industry is pivoting with or without you — prioritize preparation to keep up (or get left behind!)
  • Thinking things will never change in your capabilities to target users and measure your online marketing efforts. If recent history is any indication of what’s ahead, there’s no doubt about it — you can’t ignore these changes.
