Post-Cookie Advertising with AI

With recent changes in the digital advertising world, mostly those involving cookie deprecation, we are witnessing many new emerging methods of targeting. They are designed to deliver laser-focused precision targeting while keeping users' data safe from third parties. Most of these new methods involve AI and large language models whose capabilities seem to be growing exponentially. They may soon be (if they aren't already) the number one engine driving targeted advertising innovation. To name a few:

‍

Contextual targeting

‍

Instead of relying on user behavior tracking, this method matches ad content with the surrounding context of the site. We have known this type of targeting for many years but with the latest development in the world of AI, scraping and analyzing the content of the webpages or apps has improved significantly in both precision and time.

Previously, context analysis relied on either keyword-based methods or predefined lists of domains and subdomains within a given topic. Unlike these traditional approaches, LLMs can read an article's content and, through nuanced analysis, determine its relevance to a client's target group. Market leaders leverage LLMs at scale, a challenge that requires significant expertise to achieve cost-effectively. Because context analysis doesn't require personal data collection or individual user profiling, it naturally respects user privacy while still ensuring that ads remain relevant and timely.

Topics API

‍

The Topics API is an alternative to old cohort-based targeting, using algorithms for leveraging the user's browsing behavior to place them into a few specific interest categories, such as Sports or Travel & Transportation. Instead of gathering data about individual actions, it recognizes most important topics that precisely reflect current interests, saving and updating this information locally on the device to maintain privacy.

The Topics API itself is not a targeting system. It is an AI-powered tool built into the Chrome browser that provides information to targeting systems. As such, it can serve as an additional signal influencing impression purchases and ad delivery to users.

Dynamic Creative Optimization

‍

Dynamic Creative Optimization (DC)  leverages AI to automatically customize ad content in real-time based on aggregated user data and contextual signals. Instead of using intrusive tracking, AI algorithms analyze patterns in how different creative elements, such as images, headlines, and calls to action, perform across various audience segments. You may think of it as A/B testing in real-time and on a vast scale.

This method continuously tests and refines ad combinations, ensuring each user is served the most relevant creative variant without compromising individual user’s privacy.

With the rise of privacy-preserving targeting technologies, such as Protected Audience API, DCO can also be used with anonymized data to enhance ad engagement and performance while keeping up with new emerging privacy regulations.

AI-Powered Analytics

‍

Today, advanced LLMs can predict future user actions by analyzing historical and real-time data, including purchase histories, website interactions, and other contextual signals. These analyses can also provide A/B testing insights or suggest better creative strategies for the decision-makers.

All of this enables marketers, even those without technical expertise like SQL knowledge, to leverage sophisticated tools for identifying user behavior trends. This predictive approach empowers brands to deliver highly relevant content at the perfect moment while preserving user privacy and data security.

‍

Conclusion

‍

Artificial intelligence is rapidly making its mark in the digital advertising landscape by connecting effective personalization and keeping user’s data private.

As AI continues to evolve, its integration into advertising strategies will not only drive greater campaign performance, more precise targeting and streamlined campaign operational setup but also foster a more transparent, privacy-conscious digital ecosystem.
