Cookieless World

Will the cookieless future kill personalized ads?

Illustrating broad knowledge about the cookieless
(Last Updated On: September 26, 2023)

The end of third-party tracking cookies is on the horizon, but it’s not as bad as you might think. Despite concerns from some advertisers that losing third-party cookies will make it impossible to deliver personalized advertising, there are already a number of effective solutions in the works to ensure that users can still enjoy relevant ads, without any privacy fears. 

Let’s take a quick dive into why third-party tracking cookies are being retired, what that means for your advertising strategy, and why it’s actually a good thing for both customers and advertisers. 

This article will cover:

  • What tracking cookies are and why they are causing privacy concerns.
  • What impact Google’s decision to retire third-party tracking cookies will have on targeting technologies.
  • How you can best prepare for the cookieless future.

Why are people worried about tracking cookies?

It is important to remember that we are not talking about cookies generally. First-party cookies, which store user data for a specific site, are an important part of how websites function and are generally not considered a point of concern. 

The problem is third-party cookies, which are used for ad retargeting and behavioral advertising across websites. These cookies are great for delivering personalized ads, however, they track users all over the internet to gather data about them, and this has raised a number of significant privacy concerns. This has already led to many browsers, such as Apple’s Safari or Mozilla’s Firefox, eliminating or limiting third-party tracking cookies. 

What does the cookieless future mean? 

Chrome has a market share of around 65%, so any decision made by Google has an enormous impact on the advertising industry as a whole. This is why it has taken Google so long to actually retire third-party cookies since the initial announcement in June 2021. The deadline has been pushed back multiple times, until 2024 for now, in order to provide advertisers with the time they need to prepare for the cookieless future.  

Google is trying to balance advertiser and user interests

Google needs to play a difficult balancing act. On the one hand, 79% of users are concerned about how their data is being used, and this has led to an explosion of ad blockers, with 34% of U.S. users using them and rising.

On the other hand, advertisers are worried that they may be unable to effectively target users with beneficial ads. However, if the privacy issue is ignored, then the advertising industry may lose the ability to directly reach out to users with personalized ads anyway as people take the problem into their own hands and simply disconnect. That would be bad for businesses and bad for users. Instead of fighting against the cookieless future, we should adapt to it, which brings us to our next question. 

Will the cookieless future kill retargeting? 

The short answer: no. At least not if you are willing to adapt your methodologies to deal with the new online landscape. 

The elimination of third-party cookies is primarily a problem for advertisers who rely on invasive tracking methods for behavioral retargeting. These methods typically require a lot of specific information about a single user, usually taken from multiple sources. 

Advertisers will be able to take advantage of the solutions already built by Google and its ad-tech partners. The Google Privacy Sandbox is testing a number of ID-less methods to group users and deliver personalized adverts to them. RTB House has been deeply involved in this process and has helped define the direction of the FLEDGE proposal. 

Google FLEDGE is a cookieless solution that allows using first-party advertiser data to place users within interest groups. Advertisers are then able to use these interest groups to deliver personalized ads to these users, without knowing the identity of any single user contained within that group. 

RTB House developed two additions to this solution from the ground up:

Product-level Turtledove (PLTD): Stores data on the products a user interacts with, within that user’s browser, enabling personalized product recommendations without knowing who a user is. 

Outcome-based TURTLEDOVE (OBTD): Uses the same approach to store signals, that help advertisers evaluate each ad impression in a better way. These signals can serve as specific variables, such as the value of products in the user’s basket. This can be used to better evaluate the bid price for a user in a private ad auction. Importantly, none of these signals can be used to re-identify and track an individual.

What can advertisers do to reach users in the cookieless future?

The shift to anonymized datasets means that successful advertisers will be competing on how well they can interpret first-party data, rather than how much individual data from multiple sources they can collect. Companies with strong artificial intelligence solutions, like RTB House’s Deep Learning algorithms, will be better equipped to function in this new environment than those without. 

With this knowledge, there are a number of ways that you can prepare yourself for the cookieless future, and we’ve compiled a checklist to help you do just that. 

Analyze your current toolkit and identify anything reliant on third-party cookies

This will enable you to figure out which solutions are worth phasing out, and help you understand what new solutions you will need to bring in to replace them. For example, for regular targeting (used in branding campaigns) you might decide to take advantage of contextual targeting solutions, instead of behavioral ones. 

Increase the role of first-party data

First-party data is a great way to understand your users. This could either be data for retargeting that you, or your client, already own from the people using your site, or it could be data useful for branding campaigns that originate from publishers about the users visiting their websites, which are unknown to you. While these two data sources cannot be tied together to re-identify users, they can be used for different purposes. Understanding how to properly use first-party data will give you a huge edge in the cookieless future. 

Talk to your adtech partners and understand if they are testing new solutions

Google is already making it possible for adtech to participate in the trials of its new solutions, notably FLEDGE. This provides advertisers with the opportunity to see how these solutions work in the real world, and tailor their approach.

The cookieless future is here – make sure you’re ready

The best time to prepare for the cookieless future was yesterday, the second-best time is right now. The RTB House team has been working hard on new solutions that are designed to operate perfectly in the cookieless future. Our Deep Learning algorithms are brilliant at interpreting complicated, even unstructured, datasets, and drawing actionable conclusions.
