In a significant update for advertisers and developers, Google has announced the deprecation of the ad sharing functionality in the Google Ads API. This change, which will take effect with the release of version 22 on October 15, 2025, will fundamentally alter how ads are created and managed at scale. To help you navigate this transition smoothly, let’s break down what’s happening, why it matters, and how you can prepare.

What Is Ad Sharing?
To begin with, ad sharing allows advertisers to create a single ad and use it across multiple Ad Groups. This approach has been a time-saving feature, enabling advertisers to avoid duplicating identical ads for different Ad Groups. Instead of recreating the same ad repeatedly, one ad could be linked to multiple Ad Groups, streamlining campaign management.
However, with the upcoming changes, this functionality will no longer be available. Let’s explore why Google is making this shift.
Why Is Google Deprecating Ad Sharing?
First and foremost, this move aligns with Google’s broader shift toward asset-based ad formats, such as Responsive Search Ads (RSAs) and Performance Max campaigns. These formats dynamically assemble ads from a pool of assets—headlines, descriptions, and images—making static, shareable ads less efficient in today’s advertising landscape.
By focusing on asset-based ads, Google aims to enhance ad relevance and performance through automation and machine learning. Consequently, advertisers will need to adapt their strategies to align with this new approach.
Key Dates and Timeline
To ensure you’re fully prepared, here’s a timeline of the key dates to keep in mind:
- October 15, 2025:
- The ability to create shared ads will be removed from all supported versions of the Google Ads API.
- Any attempt to link a single ad to multiple Ad Groups will result in an error.
- Q1 2026:
- Shared ads will stop serving entirely.
- Google will automatically convert any remaining shared ads into individual ads for each Ad Group. The original ad will remain in one Ad Group, while new copies will be created for others.
Now that you know the timeline, let’s discuss how you can prepare for this transition.
How to Prepare for the Transition
Step 1: Audit Your Application
To start, review your codebase to identify any instances of ad sharing. Specifically, look for logic that uses the AdGroupAdService to link a single ad to multiple Ad Groups. This will help you pinpoint areas that need to be updated.
Step 2: Update Ad Creation Logic
Next, refactor your workflows to create unique ads for each Ad Group. Even if the ad content is identical, each Ad Group must now have its own distinct ad object. This step is crucial to ensure compliance with the new API requirements.
Step 3: Migrate Existing Shared Ads
After auditing your application, focus on migrating your existing shared ads. Start by identifying all shared ads currently in use. For each shared ad, create a new Responsive Search Ad (RSA) in each associated Ad Group.
Additionally, use this opportunity to expand your asset pool by adding more headlines and descriptions. This will maximize the performance of your RSAs and help you achieve better results.
Step 4: Archive Historical Data
Finally, remember that performance metrics (e.g., impressions, clicks, conversions) are tied to individual ads. Export and archive historical data from shared ads before transitioning to unique ads, as new ads will start with zero performance history. This step will ensure you have access to valuable data for long-term analysis.
Automatic Migration in Q1 2026
If you’re unable to manually migrate your shared ads, don’t worry—Google will handle the transition automatically in early 2026. Here’s how the process will work:
- The original ad will remain in one Ad Group (the one with the lowest ID).
- New copies of the ad will be created for all other Ad Groups.
- Machine-generated assets, such as automated headlines, will not be transferred and will be regenerated for each new ad.
While this automated process ensures continuity, it’s still recommended to manually migrate your ads. This approach gives you greater control over ad content and performance.
Impact on Reporting and Performance
It’s important to note that switching from shared ads to unique ads will affect reporting and performance metrics. Historical data will remain accessible but will not carry over to the new ads. Therefore, it’s essential to communicate this change to your team or clients and plan for potential short-term performance fluctuations as new ads accumulate data.
Why This Matters
In summary, the deprecation of ad sharing marks a pivotal shift in Google Ads management. By embracing asset-based ad formats, advertisers can leverage automation to create more relevant and effective campaigns. However, the transition requires careful planning to avoid disruptions and ensure a seamless migration.
Final Thoughts
To conclude, the October 2025 deprecation of ad sharing in the Google Ads API is a significant change that underscores Google’s commitment to innovation in digital advertising. Advertisers and developers should act now to audit their systems, update workflows, and prepare for the future of asset-based advertising. For further details, consult the official Google Ads API documentation and stay tuned to the Google Ads Developer Blog for updates.
By taking proactive steps today, you can ensure a smooth transition and continue to achieve success in your advertising efforts.
