Google Ads 37-Month Data Retention: What to Export
Starting June 1, 2026, Google Ads keeps hourly, daily and weekly reporting data for 37 months, monthly, quarterly and annual data for 11 years, and reach and frequency metrics for 3 years (policy verbatim). After that, the data is no longer accessible via the Google Ads interface or APIs. Build a calm export habit now — Google Ads Scripts or the API into Sheets or BigQuery — before any reporting baseline you depend on ages out.
