Google Ads has announced a new data retention policy that will take effect on June 1, 2026, changing how long advertisers can access campaign performance data within the platform.
The update introduces different retention periods for detailed and aggregated reporting data, impacting advertisers, agencies, analysts, and businesses that rely on long-term campaign reporting.
While most users may not notice immediate changes, organizations that depend on historical performance analysis should understand how the new policy could affect future reporting and data storage strategies.
What Is Changing?
Under the new policy, Google Ads will retain different levels of reporting data for different time periods.
Detailed Performance Data
The following data will be available for 37 months:
- Hourly performance data
- Daily performance data
- Weekly performance data
After this period, advertisers will no longer be able to access these detailed reporting breakdowns through Google Ads.
Aggregated Performance Data
The following reporting data will remain available for 11 years:
- Monthly performance data
- Quarterly performance data
- Yearly performance data
This allows businesses to continue analyzing long-term performance trends even after detailed data expires.
Why Google Is Making This Change
Google has not positioned the update as a major platform overhaul, but the change aligns with broader industry trends involving:
- data management efficiency
- storage optimization
- long-term reporting standardization
- privacy-focused data practices
As advertising platforms continue handling enormous volumes of campaign data, retention policies are becoming increasingly important for managing infrastructure and reporting systems.
Who Will Be Most Affected?
The new retention policy is particularly relevant for:
- digital marketing agencies
- enterprise advertisers
- PPC specialists
- reporting teams
- data analysts
Organizations that routinely compare detailed campaign performance over multiple years may need to adjust how they store and manage historical data.
For advertisers who primarily review recent campaign performance, the impact may be minimal.
Why Historical Data Matters
Historical advertising data is often used to:
- identify long-term trends
- analyze seasonality
- compare year-over-year performance
- optimize bidding strategies
- evaluate marketing effectiveness
Many businesses rely on detailed daily and weekly reports to understand how campaigns performed during specific periods, promotions, or market conditions.
With detailed data now limited to 37 months, advertisers may need to plan ahead.
What Advertisers Should Do
To avoid losing valuable reporting information, advertisers should consider:
Exporting Important Reports
Businesses may want to regularly export:
- campaign performance reports
- keyword performance data
- conversion reports
- audience insights
before retention limits are reached.
Building Internal Archives
Many organizations already maintain:
- spreadsheets
- data warehouses
- business intelligence platforms
- cloud storage systems
for long-term reporting purposes.
Using External Analytics Platforms
Advanced advertisers may also use:
- BigQuery
- Looker Studio
- Tableau
- Power BI
to preserve historical advertising data beyond platform retention windows.
Impact on Agencies and Large Accounts
Marketing agencies managing large client portfolios may experience the greatest impact.
Long-term client reporting often depends on detailed historical records to demonstrate:
- growth trends
- seasonal performance
- campaign improvements
- advertising ROI
Agencies may increasingly need automated reporting and backup systems to ensure important data remains accessible.
The Growing Importance of Data Ownership
The update highlights a broader trend across the digital marketing industry:
Businesses should not rely solely on advertising platforms to store critical historical data.
As platforms continue adjusting retention policies, advertisers who maintain their own reporting archives will have greater flexibility and control over long-term performance analysis.
What Stays Available After 37 Months?
It is important to note that advertisers will not lose all historical visibility.
Even after detailed hourly, daily, and weekly data expires, users will still have access to:
- monthly performance summaries
- quarterly reports
- yearly reporting data
for up to 11 years.
This ensures long-term trend analysis remains possible, even if granular campaign data is no longer available.
Conclusion
Google Ads’ new data retention policy, effective June 1, 2026, introduces a clear distinction between detailed and aggregated reporting data. While hourly, daily, and weekly performance metrics will be retained for 37 months, monthly, quarterly, and yearly data will remain accessible for up to 11 years.
For advertisers and agencies that depend on historical campaign analysis, the update serves as an important reminder to develop data backup and reporting strategies that extend beyond platform retention limits.
