Introducing Channel-Level Reporting for Performance Max campaigns

neljapäev, 29. jaanuar 2026

Following yesterday's launch of Google Ads API v23, we are excited to share more details about one of the most highly requested features: Channel-level reporting for Performance Max campaigns. This update provides developers and advertisers with unprecedented transparency into where their Performance Max ads are serving, allowing for deeper optimization and more granular performance insights. Greater transparency with channel breakdowns Starting with v23, you can now retrieve performance data broken down by channel—such as Google Search, Search Partners, GMail, YouTube, Display, Discover, and Maps. This functionality is available at the campaign, asset group and asset level, allowing you to see how specific creative assets are performing across different environments. In previous versions of the API, using the ad_network_type segment for Performance Max campaigns typically returned a MIXED enum value. With the release of v23, the API will now return the specific channel breakdowns. Note for developers: This is a significant change in behavior. When you upgrade your queries to v23, you will begin to see more detailed results than in previous versions. Please ensure your reporting systems are prepared to handle these specific enum values instead of the generic MIXED result. Additional segments to consider While the channel breakdown is new to v23, it works in tandem with powerful segmentation fields introduced in v22: ad_using_product_data and ad_using_video.

ad_using_product_data: Use this segment to distinguish performance between ads that utilize your Merchant Center product feed versus those that do not.

ad_using_video: This segment allows you to isolate performance data for ad impressions that included a video component.

By combining these segments with the new v23 channel reporting, you can now gain highly specific insights, such as understanding the conversion value of video-based ads specifically on the YouTube channel versus the Display Network. Or if you’re a retailer, use the ad_using_product_data segment to see data for Shopping ads for Search, Dynamic Remarketing ads for Display and video ads that showcase your products on YouTube. Implementation details To get started with these new reporting capabilities, you should update your client libraries to v23. You can find detailed technical documentation and example queries in our PMax reporting guides. Important notes:

Performance reports will only return channel-level data for dates on or after June 1, 2025.

While channel reporting is available at the campaign, asset group, and asset levels via the API, reporting at the asset group level is exclusive to the API and will not be available in the Google Ads web interface.

If you have any questions or want to discuss this post, please reach out to Google Ads API support or start a discussion on our “Google Advertising and Measurement Community” Discord server.

Unlocking enhanced Performance Max targeting in the Google Ads API

esmaspäev, 4. august 2025

This blog post was updated on August 12, 2025 to add clarification on how to attach a negative keyword list to your campaign. We're excited to announce the launch of three powerful new features for Performance Max campaigns within the Google Ads API. These updates will give you greater control and flexibility over your Performance Max campaigns, allowing for even more precise targeting and optimization. Available today across all supported versions of the Google Ads API, these features empower developers and advertisers to refine their Performance Max strategies. Introducing new targeting capabilities1. Device targeting With the introduction of device targeting, you now have the ability to specify at the campaign level where your Performance Max ads will appear. This feature provides a new layer of control, enabling you to optimize your campaign reach across various platforms. To set up device targeting, add a DeviceInfo criterion to your Performance Max campaign. 2. Negative keyword lists To help prevent your ads from showing for irrelevant searches, we're introducing support for negative keyword lists at the campaign level on Performance Max campaigns. This highly requested feature allows you to upload and apply lists of keywords that you want to exclude, ensuring your ads are displayed to the most relevant audience. You can attach a negative keyword list to your campaign by attaching a SharedSet with the type NEGATIVE_KEYWORDS using the CampaignSharedSetService. Refer to this page for an example on how to attach a negative keyword set to a campaign. 3. Age range exclusions We're also adding the capability to exclude specific age ranges from your Performance Max campaigns. This allows for more granular audience targeting, which helps you comply with age-related advertising regulations and focus your spend on the most appropriate demographics for your products or services. To set up an age range exclusion, add an AgeRangeInfo as a negative criterion on your PMax campaign. How to get started These new features are available starting today on all supported versions of the Google Ads API. For detailed documentation on how to implement these new targeting options in your Performance Max campaigns, refer to our developer guides. We're committed to continually enhancing the Google Ads API to provide you with the tools you need to succeed. We encourage you to explore these new features and incorporate them into your Performance Max strategies to achieve even better results.

What you need to know about the business name and logo asset migration in PMax Campaigns

esmaspäev, 14. juuli 2025

What’s changed? Today, we're excited to announce that the brand guidelines rollout is now complete for all new Performance Max campaigns created through the Google Ads UI, with API-created accounts soon to follow. As was first announced in December, this means that new PMax campaigns initiated in the UI will have brand guidelines enabled by default, offering advertisers greater control over their brand's representation. With brand guidelines rolling out to more Performance Max campaigns, it is crucial to understand how this impacts campaigns you interact with via the API, and for you to update your code in advance to prepare for it. What do API Users need to update now? Previously, brand assets such as your business name and logo were associated with Asset Groups. Currently, for any PMax campaign with brand guidelines enabled, these brand assets are now stored at the campaign level. This means if your application queries or modifies brand assets for PMax campaigns, you must adjust your code to look for these assets in CampaignAsset instead of AssetGroupAsset for these campaigns. Accounting for both asset locations in your application is vital to ensure your integrations continue to function as expected. To determine if brand guidelines are enabled for a PMax Campaign, check the Campaign.brand_guidelines_enabled field. What do API Users need to plan for in the future? Brand guidelines will be enabled by default when creating PMax Campaigns using the API beginning in v21. You can optionally disable brand guidelines by setting the Campaign.brand_guidelines_enabled field to false on-creation. The default behavior for brand guidelines on new Performance Max campaigns created via the API remain disabled for all supported versions through v20. To manually turn on brand guidelines through the API, you have two options:

Starting in v19, all API users can choose to manually enable brand guidelines when creating a new PMax campaign. To do so, you need to set the Campaign.brand_guidelines_enabled field to true during campaign creation. You can refer to the “Add Performance Max Campaign” code sample for an example of how to create a campaign with brand guidelines enabled.

To manually enable brand guidelines for an existing campaign, use CampaignService.EnablePMaxBrandGuidelines. Set auto_populate_brand_assets to true to automatically populate the campaign with top-performing brand assets. Disabling brand guidelines for a campaign after its creation is not supported.

There is an in-progress automatic migration to enable brand guidelines for existing campaigns. As previously announced, this migration has already begun on a rolling basis by CID. Only campaigns that use the same logos and business name across all asset groups will be automatically migrated. We anticipate the migration to be completed for all applicable CIDs by October 30th. In the meantime, we encourage you to use the existing migration endpoint to manually update your campaigns to brand guidelines at your own pace.

New UI-Only Image Optimization Features for Performance Max Campaigns

teisipäev, 20. mai 2025

This post was recently updated to reflect that API support for these settings will be included in v21. We're providing an important update regarding new image optimization features rolling out in the Google Ads user interface, specifically impacting Performance Max campaigns. What are these new UI features?

Landing Page Images: This setting allows Google AI to automatically source relevant images directly from your ad's landing page. The aim is to dynamically incorporate these visuals into your ads, potentially improving relevance and extending your reach across more placements.

Image Enhancements: With this feature, Google AI can automatically make improvements to your uploaded image assets. This can include smart cropping to create different versions of your images, helping to unlock more ad inventory and boost performance. Future enhancements may also include capabilities like uncropping or animating images.

You can find more information about these features in the Google Ads Help Center. Default behavior: Image enhancements will be enabled for all Performance Max users. For Landing Page Images, the setting will be enabled on PMax only if the account level Dynamic Image setting is active. Note that enabling the account-level Dynamic Image setting requires manual opt-in through the UI. Key Information for API Users: At this time these new UI features for Performance Max campaigns can only be managed with the Google Ads user interface. API control of these settings will become available in version 21.

These features will not be viewable through the Google Ads API.

At this time, you will not be able to opt-in or opt-out of these new settings (Landing Page Images and Image Enhancements) using the Google Ads API. To change the status of these settings you must use the Google Ads UI.

API Integration Impact: Your existing API integrations will continue to function for the features and settings currently supported by the API. However, these new additional Performance Max settings will need to be managed by your users directly in the Google Ads interface. We encourage you to familiarize yourselves with the details provided in the Google Ads Help Center to understand the scope of these UI changes for Performance Max campaigns. This will enable you to effectively support your users and clarify what can and cannot be controlled via the API. We are committed to keeping our developer community informed. Stay tuned to this blog for further updates on control of these image optimization settings in the Google Ads API.

Upcoming changes to enable brand guidelines in Performance Max

kolmapäev, 18. detsember 2024

Starting on January 20, 2025, new Performance Max (PMax) campaigns created with the UI will have brand guidelines enabled and require business name and logo brand assets to be linked at the campaign level rather than the asset group level. Brand guidelines is a new feature that allows you to control how your brand is represented in your Performance Max campaign automated assets or formats. What this means for API users New PMax campaigns created in the UI with brand guidelines enabled will automatically link BUSINESS_NAME, LOGO, and LANDSCAPE_LOGO via the CampaignAsset resource rather than by using the AssetGroupAsset resource, which may impact integrations that attempt to report on or update these assets. You can check if brand guidelines are enabled for a PMax campaign by referencing the Campaign.brand_guidelines_enabled field. As of v18 of the Google Ads API, it is not possible to create brand guidelines-enabled PMax campaigns via the API, which means new campaigns must link BUSINESS_NAME, LOGO, and LANDSCAPE_LOGO assets using the AssetGroupAsset resource. In a future release, you will be able to create and fully manage PMax campaigns with brand guidelines enabled. It is important to note that the same asset requirements will continue to apply to all PMax campaigns regardless of whether or not brand guidelines are enabled. However, BUSINESS_NAME, LOGO, and LANDSCAPE_LOGO asset requirements will be evaluated at the campaign level for campaigns with brand guidelines enabled and the asset group level for campaigns without brand guidelines enabled. You can reference the relevant section of our Performance Max optimization and troubleshooting guide for more information, and as always, contact our team if you need support.

Change to updates of Google Ads custom audience types

teisipäev, 8. august 2023

Starting September 27, 2023 you will see a change if you use custom audiences. You will no longer be able to update a custom audience type once you create the custom audience. For example, if you set the type to AUTO or INTEREST, then you cannot update it to the type SEARCH in the Google Ads API. This change ensures that your campaign continues to serve by making sure that your custom audience remains eligible. What do I need to change? Modify your code so it avoids attempting to update the type of an existing CustomAudience. If your code attempts to update the type field after September 27, 2023 then the API will return a CustomAudienceError.INVALID_TYPE_CHANGE error. Where can I get support? If you have questions, please reach out to us on the forum or at googleadsapi-support@google.com.
