Google released version 25.2 of its Ads API on September 23, 2026, introducing significant new features for competitive benchmarking and expanded controls for Performance Max campaigns. These updates provide marketing operators and developers with enhanced programmatic capabilities for campaign management and optimization, offering deeper insights into market position and more granular control over campaign targeting.
Before this release, competitive benchmark data was not directly accessible via the API, often requiring external analysis. Performance Max campaigns also had fewer granular controls for asset groups and targeting. With v25.2, developers can now integrate competitive benchmark percentile data directly into their reporting tools and dashboards, while advertisers gain more programmatic visibility and control over Performance Max asset groups, URL tracking, gender exclusions, and the strategic use of search themes.
Google Ads API v25.2: An Overview of Key Updates
The Google Ads API v25.2 update, launched on September 23, 2026, brings competitive benchmarking, expanded Performance Max controls, and new developer-focused reporting and recommendation features. This release is designed to give advertisers and platforms greater programmatic visibility into their market standing and more precise control over Performance Max (PMax) asset groups and URL tracking, according to SEOteric Digital Marketing. The update also introduces percentile-based benchmarks and enables AssetGroup-level URL options.
This version is supported until August 2027, with version 26 scheduled for release in October 2026. Developers are advised to update their client libraries to v25.2 to access these new functionalities. The enhancements aim to streamline the integration of market insights and offer more refined control over automated campaign types, directly impacting how advertisers can programmatically manage and optimize their campaigns.
Competitive Benchmarks: Gaining Market Insight
A key new feature in Google Ads API v25.2 is the availability of competitive benchmark percentile data. The Google Benchmarks Service now allows developers to see how a client's performance compares to other advertisers within specific ranges, using percentiles. This provides an additional layer of comparison for account performance that was previously unavailable directly through the API, as reported by ALM Corp. Developers can now integrate this perspective directly into their existing campaign data retrieval processes, moving beyond manual analysis.
This benchmark data allows developers to request percentile information to see how an advertiser ranks against an "all advertisers" benchmark. They can also apply category filters, which lets the comparison focus on a specific market segment instead of the entire pool of advertisers, according to ALM Corp. Integrating competitive benchmarking into agency dashboards and reporting tools can offer a significant advantage, allowing agencies to display benchmark views alongside campaign results rather than performing separate comparisons. This programmatic access to competitive data enables more informed strategic adjustments and performance analysis.
