Google has posted an update and emailed advertisers on changes to its Google Ads data retention policy. What changed? Here is what Google said.
First of all, these changes apply as of May 1, 2026.
- The hourly, daily and weekly reporting data collected by Google Ads for periods of time shorter than one month will be available for 37 months.
- Monthly, quarterly and annual data is available for 11 years.
- After that period, the data will not be accessible via the Google Ads interface or APIs.
The email that was sent out says this is not happening May 1st, but rather June 2026. The email reads, "Starting on June 1, 2026, Google Ads will adjust the availability of performance reporting data at specific granularities."
Here is a screenshot of the email from Anthony Higman on X and Arpan Banerjee on LinkedIn:
The Google Ads developer blog also broke this down in more detail for how this impacts the Google Ads APIs and other Google APIs.
