Starting June 1, 2026, Google Ads is changing its data retention policy. Historical campaign data beyond the new retention window will become inaccessible through the standard interface - no warnings, and no recovery after the deadline passes.
For US advertisers and agencies, this is a concrete operational deadline. Google Ads is the dominant paid search platform in the American market, and the historical data it holds - campaign performance, keyword history, conversion data, audience segments - informs budget planning, seasonality modelling, and competitive analysis. After June 1, 2026, part of that data will be gone from standard view.
In brief: Google Ads is restricting access to historical data from June 1, 2026. Affected: campaign statistics, keyword history, audience data, Auction Insights, conversion history, Search Terms Reports, ad creative performance. Storage alternatives: GA4, BigQuery, Looker Studio, Supermetrics, Funnel.io.
What Changes on June 1, 2026
From June 1, 2026, Google Ads introduces restrictions on historical data availability. Data outside the new retention window will no longer be accessible through the standard Google Ads interface or standard API requests.
This is not data deletion - it is access restriction. Google Ads continues operating and accumulating new data. But historical reports for periods outside the new retention window will be unavailable for viewing or export through standard channels.
What this means for US advertisers:
- Year-over-year comparisons through the standard interface will be limited to data within the retention window
- Custom report date ranges extending beyond the window will stop returning data
- Audience segments built on historical data may lose underlying data
- Retrospective analysis of past campaigns through the interface will be restricted
What Data Becomes Inaccessible
Campaign and ad group performance statistics Historical metrics (clicks, impressions, CTR, CPC, ROAS) for periods outside the retention window will be unavailable through the standard interface.
Keyword history Keyword performance data - bids, Quality Scores, positions, traffic - for past periods.
Audience data Historical custom audience data, remarketing list composition, similar audience data.
Auction Insights Historical Auction Insights used to track impression share and competitive positioning over time.
Conversion history Detailed conversion data for past periods - broken down by type, source, campaign - for seasonality modelling and comparison.
Search Terms Reports Search Terms Reports for historical periods outside the retention window.
Ad creative performance history Per-variant performance data for past ad copy - useful for creative testing retrospectives.
Who Is Most Affected in the US Market
US agencies managing multiple client accounts Agency accounts typically hold years of historical client data used for benchmarking, reporting, and justifying strategy. Every affected client account needs to be exported before the deadline.
E-commerce advertisers with seasonal planning cycles US e-commerce advertisers (Amazon Sellers, DTC brands, retail chains) use historical Google Ads data to plan Q4 campaigns, Black Friday/Cyber Monday budgets, and summer promotions. Losing access to multi-year seasonality data through the interface directly affects planning accuracy.
Financial and insurance advertisers in high-CPC categories Financial services (insurance, mortgages, credit cards) run in some of the most competitive and expensive Google Ads categories. Long-term keyword and Auction Insights history is used for bid strategy and competitive analysis - that history is at risk.
Teams running attribution or forecasting models Marketing science teams building models on Google Ads historical data lose part of their training data. This affects forecast accuracy for accounts that haven't configured BigQuery export.

Alternatives for Long-Term Data Storage
Google Analytics 4 (GA4) GA4 stores user data for up to 14 months depending on property settings. For US accounts with GA4 integration and auto-tagging enabled, some Google Ads attribution data is already captured in GA4. GA4 does not replicate all Google Ads data - it complements it.
BigQuery Export Google Ads data export to BigQuery via the Data Locker API or a linked Google Cloud project is the most complete long-term solution. Data is queryable via SQL with no platform-imposed retention limits beyond what you configure in BigQuery.
Looker Studio Automated connection of Google Ads data to Looker Studio, with underlying data stored in Google Sheets or BigQuery. Provides visualisation alongside a data backup layer.
Google Sheets with Scheduled Exports Manual or script-automated export of key report dimensions to Google Sheets on a weekly or monthly schedule. Practical for smaller accounts or specific data categories where full BigQuery setup is unnecessary.
Third-party tools
- Supermetrics: pulls Google Ads data into Google Sheets, BigQuery, or data warehouse destinations on a schedule
- Funnel.io: multi-channel marketing data aggregation and storage
- Data Locker API: direct Google-managed export to Google Cloud Storage, suitable for high-volume accounts
FAQ
What is changing in Google Ads on June 1, 2026?
Google Ads is restricting access to historical campaign data beyond the new retention window. Data will be inaccessible through the standard interface and standard API requests. This is not data deletion - it is a platform access restriction.
Which data does the new policy affect?
Campaign and ad group statistics, keyword history, audience data, Auction Insights, conversion history, Search Terms Reports, and ad creative performance data.
What should US advertisers do before June 1, 2026?
Export historical data across all affected categories. For ongoing long-term protection, configure BigQuery Export via Data Locker API or set up Supermetrics with a scheduled export to a data warehouse.
Are there alternatives to exporting data manually?
Yes. BigQuery Export (via Data Locker API), Supermetrics, and Funnel.io can automate ongoing data extraction and storage. These should be configured before June 1, 2026 to capture data continuously - not just as a one-time pre-deadline export.
Does this affect all US Google Ads accounts?
Yes. The policy change is global and applies to all Google Ads accounts, including US accounts at all spend levels.
Conclusion
June 1, 2026 is a hard deadline for US Google Ads advertisers: historical data beyond the new retention window becomes inaccessible. For agencies and advertisers with multi-year account histories, the window to act is narrow - export what you need now.
Use the checklist: campaign statistics, keywords, audiences, Auction Insights, conversions, Search Terms. For systematic long-term protection, configure BigQuery Export or Supermetrics before the deadline. Manual one-time export is not enough if you need continuous historical accumulation going forward.
