On June 1, 2026, Google Ads' new data retention policy takes effect. Granular reporting data (hourly, daily, weekly) is kept for only 37 months; monthly-to-annual data stays 11 years; reach & frequency, 3 years. After that, it disappears from both the interface and the API. On the paid side, it's an archiving issue. Strategically, it's a reminder: the data you rent from a platform is ephemeral, unlike the visibility assets you own.
On June 1, 2026, Google Ads begins enforcing its new data retention windows, announced on May 1, 2026 by Nadine Wang of the Advertising and Measurement APIs team on the Google Ads Developer Blog. From that date, reporting data covering periods shorter than one month — hourly, daily and weekly views — stays accessible for only 37 months. The official Google Ads Help Center page spells out the tiers: monthly, quarterly and annual data remains available for 11 years, and reach & frequency metrics for 3 years. Past those windows, the data can no longer be viewed, in the interface or via the API.
For the first time, Google is putting an explicit expiration date on the finest numbers in your campaigns. Until now, many advertisers treated their Google Ads history as a permanent vault. That's no longer true.
The retention windows, in plain terms
| Data type | Retention |
|---|---|
| Hourly / daily / weekly (periods < 1 month) | 37 months |
| Monthly / quarterly / annual | 11 years |
| Reach & frequency | 3 years |
The stakes aren't trivial for anyone managing campaigns seriously. Seasonality analysis, multi-year benchmarking and media mix modeling rely precisely on several years of granular data. A weekly view from 2026 won't be there to compare in 2030. Advertisers, agencies and analytics teams now have a fresh incentive to export and warehouse their history before it leaves the window.
Why this goes beyond paid search
You could file this under "ad data housekeeping" and move on. That would miss the signal. Because the same logic applies, more quietly, to nearly all your marketing measurement sources: the data a platform holds is lent to you, not given. Search Console, for instance, keeps only 16 months of performance history. Analytics tools change their schema, deprioritize old metrics, or shut down. You're building decisions on shifting ground.
This echoes a deeper shift we've been documenting for months. On one side, AI Overviews now capture 86% of business queries in France and erode the organic click, blurring how you read your traffic data. On the other, rankings themselves are getting more volatile, as the May 2026 core update volatility showed. And advertising is migrating into new generative surfaces, like OpenAI's Ads Manager introducing GEO budget targeting inside ChatGPT. In this landscape, what you own matters more than what you rent.
Key takeaway: Google Ads' limited retention isn't an SEO problem. It's an SEO argument. It illustrates how fragile rented assets are next to the ones you hold: your content, your site, your brand authority in AI answers.
What this changes for SMBs and their marketing teams
In practice, if you run Google Ads, three deadlines are approaching:
- your oldest granular data will start disappearing as it slides out of the 37-month window;
- fine-grained multi-year reports (hour by hour, day by day) will become impossible to reconstruct after the fact;
- any attribution or modeling logic that assumes a complete history will have to rely on your own exports, not Google's memory.
And beyond paid search, it's a chance to ask the real question: how much of your visibility rests on channels whose data and rules you don't control? The answer mechanically pushes toward organic and GEO, where the asset (published, indexed, cited content) belongs to you for the long run — a logic close to that of content licensing deals between AI and publishers, where value flows to whoever owns the source.
What to do now: 4 concrete actions
- Export your granular Google Ads history before the deadline. Set up a scheduled export (BigQuery Data Transfer, a connector to your data warehouse, or at minimum monthly CSV exports). It's the only way to keep your fine-grained views beyond 37 months.
- Run the same audit on your other sources. Search Console (16 months), analytics, social platforms: identify the retention windows and automate the backup of what matters to your decisions.
- Rebalance toward assets you own. An article that ranks and gets cited by ChatGPT keeps working for years, with no dependency on a third party's retention policy. That's memory that belongs to you.
- Measure visibility, not just clicks. In a world of AI Overviews and generative answers, also track your mentions and citations in AI — a metric you build, independent of the ad platform's counters.

Our take
At Cicéro, we read this announcement as a healthy wake-up call: in digital marketing, you only own what you archive and what you publish. Google can cap your data retention tomorrow, AI can absorb your clicks today — but a reference piece of content, indexed and cited, stays an asset no one unplugs on your behalf. Export your data, and invest where the value comes back to you.
What this article doesn't cover: this isn't a deletion of your live campaign history nor a billing change. Exact durations can vary by account and metric type; refer to the Google Ads Help Center for your specific case. We put forward no numerical estimate of the impact on your performance: Google doesn't publish that data and we don't speculate.
