How Google's Topics API Will Revolutionize Google Ads Targeting
August 24, 2023

As the digital advertising landscape continues to evolve, Google Ads remains at the forefront, constantly introducing innovative features and technologies to enhance targeting capabilities.

One such groundbreaking development is the Topics API by Google Sandbox. This powerful API promises to revolutionize the way advertisers reach their target audience, enabling them to create more effective and tailored ad campaigns.

Understanding the Topics API by Google Sandbox

The Topics API is a powerful tool provided by Google Sandbox that allows advertisers to access a vast array of topic data.

It provides real-time insights into users’ interests, preferences, and behavior, thereby enabling advertisers to refine their targeting strategies. This tool is focused on Interest-based Advertising (IBA) instead of the current 3rd party cookies.

Browser-Based Topic Determination

The Topics API operates within the user’s browser, utilizing browsing history to determine a selection of topics that represent the user’s top interests for a given week.

This means that the API analyzes the user’s browsing behavior locally on their device without involving external servers or Google servers. By keeping the topic determination process within the browser, user data remains private and secure.

Temporary Storage and Data Deletion

The Topics API stores the selected topics for a limited duration of only three weeks.

After this period, the old topics are automatically deleted from the browser. This practice ensures that user data is not retained indefinitely and adds an extra layer of privacy protection.

Limited Topic Sharing

When a user visits a participating website, the Topics API selectively shares a maximum of three topics (one from each of the past three weeks) with the website and its advertising partners.

This sharing is done on the user’s device without transmitting the data to external servers. By limiting the shared topics and keeping the process local, the Topics API minimizes data exposure and maintains user privacy.

Sensitive Category Exclusion

Topics curated by the Topics API are thoughtfully designed to exclude sensitive categories, such as those based on gender or race.

By proactively excluding such categories, the Topics API ensures that advertising targeting is respectful and avoids perpetuating discriminatory practices.

User Control and Transparency

Google Chrome, the browser used for implementing the Topics API, provides users with granular control over the topics feature.

Users have the option to view the topics assigned to them, remove any topics they don’t wish to be associated with, or disable the feature entirely.

Real-Time Optimization and Agility

With the Topics API, advertisers can constantly monitor and analyze topic data in real-time.

This enables them to optimize their campaigns on the fly, making data-driven decisions based on the latest insights.

Advertisers can quickly adapt their targeting strategy to align with changing user interests, ensuring their ads remain relevant and impactful. The Topics API empowers advertisers with the agility needed to stay ahead of the competition in an ever-evolving digital landscape.


The Topics API not only revolutionizes targeting in Google Ads but also prioritizes user privacy and data protection.

By operating entirely within the browser, limiting data storage, selectively sharing topics, offering user control, and thoughtfully curating sensitive categories, the Topics API ensures that users can enjoy personalized ad experiences while maintaining their privacy.

This combination of powerful targeting capabilities and robust privacy measures makes the Topics API a significant step forward in digital advertising that respects user privacy.
