Google Ads will implement new data retention limits for historical performance data across its interface and APIs starting June 1, 2026, significantly altering how advertisers access past campaign information.

The global change will require advertisers to proactively export and store older granular data if they need it for audits, forecasting or long-term campaign analysis beyond the new retention windows.

Under the new policy, hourly, daily and weekly Google Ads reporting data will be accessible for 37 months.

Monthly, quarterly and annual reporting data will have a longer retention period of 11 years, according to information from Google Ads.

Reach and frequency metrics will be subject to a shorter three-year retention limit, impacting advertisers who rely on these specific insights for their strategic planning.

The new limits will apply comprehensively to both the Google Ads interface and its various APIs, affecting automated reporting systems and services like the BigQuery Data Transfer Service.

This change means that any third-party tools or internal systems that pull historical data via Google Ads APIs will also be subject to these new restrictions.

Advertisers like Jordan Fry, mentioned by TalkNerdie2Me, who require access to data older than the specified retention periods, must establish independent archiving strategies before the June 2026 deadline.

Google Cloud and Google Analytics, while related, operate under their own data policies, but the Google Ads changes specifically target performance data within the advertising platform itself.

The company indicated that the move aims to streamline data management and improve system efficiency, though it places a new burden on advertisers for long-term data preservation.

Search Ads 360, another Google advertising product, may also see implications depending on its integration with the core Google Ads data infrastructure.

Industry observers suggest that this shift underscores a broader trend toward more stringent data management practices across major digital platforms.
