Google AdSense Authorized Buyers to Replace Ad Network Blocking

Google AdSense is continuously evolving to enhance user experience and provide advertisers with better tools to connect with audiences. As part of this ongoing development, significant changes are set to occur in November 2025, specifically regarding the way blocking controls function within the platform. Understanding these changes is crucial for publishers looking to maintain effective brand safety while maximizing their ad revenue.

Changes to Google AdSense Blocking Controls

On November 6, 2025, Google will implement a pivotal update to its AdSense platform by replacing the existing "Ad networks" blocking control with a new feature known as "Authorized Buyers." This shift aims to refine how publishers can manage their ad inventory and ensure that only trusted networks have access to their content.

The change means that the current option to block ad networks will cease to exist, making way for a more streamlined and effective approach to brand safety. Google has stated that this new control will not include inactive ad networks, test ad networks, or those connected to Display & Video 360 (DV360) networks, thus improving the quality of ads served.

What Are Authorized Buyers?

Authorized Buyers are entities that have programmatic access to Google's Partner Inventory, which comprises ad inventory from reputable publishers and developers using Google Ad Manager, AdMob, and AdSense. This includes:

• Ad networks
• Trading desks
• Demand-side platforms (DSPs)

This programmatic access allows these buyers to compete for ad space in an auction environment, which potentially increases revenue for publishers while ensuring that ads come from verified sources.

New Features on the Authorized Buyers Page

The introduction of the "Authorized Buyers" page will provide publishers with enhanced controls and visibility. Key features include:

• The ability to allow or block specific authorized buyers from bidding on their inventory.
• Improved insights into the relationships between different authorized buyers, including parent-child structures.
• A more intuitive interface for managing these settings.

This level of control is designed to empower publishers to safeguard their brands while optimizing their ad revenue streams more effectively.

Removing Automatic Allowances

Another significant update is the removal of the "Automatically allow new Google-certified ad networks" setting. From the launch date, new authorized buyers will be added by default, meaning publishers will need to actively manage their settings to ensure only preferred buyers have access to their inventory.

If publishers currently have the automatic allowance feature disabled, Google recommends they enable it before the transition occurs. This will help them acclimate to the upcoming changes and ensure a smoother shift to the new system.

Guidelines for Transitioning to the New System

To facilitate the transition to the new "Authorized Buyers" control, Google offers a few guidelines:

• Check your current blocking controls settings and adjust as necessary.
• Familiarize yourself with the new "Authorized Buyers" page through a view-only version available after November 6, 2025.
• Access the page by signing into your AdSense account, navigating to Brand safety, then Content, and finally Blocking controls.

By following these steps, publishers can ensure they are well-prepared for the upcoming changes and continue to maintain effective brand safety strategies.

Implications for Ad Revenue and Brand Safety

The changes coming to Google AdSense will significantly impact how publishers manage their ad revenue and brand safety. By limiting the number of networks that can bid on their inventory, publishers can expect:

• A reduction in unwanted or irrelevant ads.
• An increase in the quality of ads displayed on their sites.
• Potentially higher revenue due to more competitive bidding among trusted networks.

These benefits align with Google's broader commitment to enhancing the advertising ecosystem, ensuring that both publishers and advertisers can thrive in a mutually beneficial environment.

Preparing for the Future of AdSense

As the digital advertising landscape continues to evolve, it is essential for publishers to stay informed about changes in platforms such as Google AdSense. By understanding the new "Authorized Buyers" system and its implications, publishers can take proactive steps to safeguard their brand while maximizing ad revenue. This preparation may include:

• Regularly reviewing and updating blocking controls.
• Engaging with the Google AdSense community for insights and best practices.
• Monitoring the performance of authorized buyers to ensure optimal ad placements.

Staying ahead of these changes will help publishers adapt effectively and maximize the potential of their advertising strategies in the years to come.
