What Google Ads’ New Data Retention Policy Means for Your Business

Google has introduced a significant change to how long advertisers can access historical reporting data. While this update may not affect day-to-day ad campaign management for most businesses, it has important implications for reporting, long-term performance analysis, and data-driven decision-making.

For businesses that rely on historical campaign data to measure growth, benchmark performance, or guide future marketing strategies, understanding this change is becoming increasingly important.

In this article, we'll break down what has changed, who is affected, and what businesses should be doing now to avoid losing valuable insights.

What Has Changed?

As of 1 June 2026, Google Ads has implemented a new data retention policy for reporting data. Under the updated rules:

• Daily, weekly, and hourly performance data will only be available for 37 months.
• Monthly, quarterly, and yearly reporting data will remain available for 11 years.
• Once data exceeds these retention periods, it will no longer be accessible through the Google Ads interface or APIs.

In simple terms, businesses can still view long-term performance trends, but the detailed day-by-day reporting data many advertisers rely on will eventually disappear.

For organisations that have been running campaigns for several years, this represents a substantial shift in how historical data can be accessed and analysed.

Why Is Google Making This Change?

Like many technology platforms, Google continues to place a stronger focus on data governance, privacy, and infrastructure efficiency.

The change aligns with Google's broader approach to data management and retention controls while also reducing the amount of granular historical information stored across its advertising systems.

While Google has not positioned this as a privacy update for advertisers directly, it reflects the wider industry trend towards more controlled data retention practices.

Why Businesses Should Pay Attention

At first glance, losing access to data older than 37 months may not sound particularly concerning.

After all, many businesses focus on the last 30, 60, or 90 days when evaluating campaign performance.

However, for larger organisations and businesses investing heavily in digital advertising, historical data often plays a much bigger role.

Detailed historical reporting is commonly used for:

• Year-on-year comparisons
• Seasonal performance analysis
• Budget forecasting
• Long-term trend identification
• Multi-year campaign benchmarking
• Executive reporting

Once detailed daily and weekly data is removed, those insights become significantly harder to access.

A business that wants to compare daily performance from four or five years ago may no longer have the information available inside Google Ads.

The Impact on Different Business Sizes

The significance of this update largely depends on the size and maturity of your advertising strategy.

Small Businesses

For many small businesses, the impact may be relatively minor.

Most local businesses focus on:

• Current lead generation
• Monthly reporting
• Recent campaign performance

If campaigns have only been running for a year or two, the new retention limits are unlikely to create immediate challenges.

That said, businesses should still maintain copies of important reports and campaign performance data.

Historical information often becomes more valuable as a business grows.

Medium-Sized Businesses

For medium-sized businesses, the update becomes more relevant.

Many organisations at this stage begin analysing:

• Seasonal trends
• Year-on-year growth
• Campaign performance across multiple years

The loss of granular historical data can make these comparisons less accurate.

Businesses relying on Google Ads as their primary reporting archive may find themselves missing important context in future reporting cycles.

Enterprise and Large Businesses

Enterprise organisations are likely to be the most affected.

Large businesses often:

• Run campaigns continuously for years
• Compare performance across multiple economic cycles
• Analyse detailed historical trends
• Build forecasting models using long-term data

For these organisations, daily-level reporting data is often extremely valuable.

Losing access to data older than 37 months can significantly reduce visibility into long-term advertising performance unless proper archiving systems are already in place.

Why Historical Data Matters More Than Most Businesses Realise

Many businesses only appreciate the value of historical data when they need it.

Imagine trying to answer questions such as:

• How did our campaigns perform before a website migration?
• Which strategy generated the best results three years ago?
• How did market conditions affect lead costs during a previous economic cycle?
• What was our average cost per lead during a specific seasonal period?

Without detailed historical reporting, answering these questions becomes much harder.

As digital marketing becomes increasingly competitive, long-term insights often provide a valuable advantage when making strategic decisions.

What Businesses Should Be Doing Now

The good news is that businesses still have options.

The most important step is ensuring valuable historical data is preserved before it becomes unavailable.

Export Important Reports

Businesses should identify which reports are critical for long-term analysis and export them regularly.

This may include:

• Campaign performance reports
• Conversion reports
• Keyword data
• Search term reports
• Audience insights

Creating a structured reporting archive can help protect against future data limitations.

Consider External Data Storage

Many larger businesses already utilise:

• Data warehouses
• Business intelligence platforms
• Reporting dashboards
• BigQuery integrations

Google has confirmed that data already transferred into external systems such as BigQuery remains available even after retention limits apply within Google Ads.

For businesses relying heavily on historical analysis, external storage may become increasingly important.

Review Reporting Processes

This update is also a good opportunity to review how your organisation handles reporting.

Questions worth considering include:

• Are reports being archived properly?
• Is historical data stored outside Google Ads?
• Are executives relying on reports that may become unavailable later?
• Are year-on-year comparisons documented elsewhere?

Many businesses discover gaps in their reporting processes only after historical data has already been lost.

Data Is Becoming a Competitive Asset

One of the broader trends emerging across digital marketing is the growing importance of first-party data and business-owned information.

Platforms like Google Ads continue to evolve, and businesses have less control over data access than they once did.

This means organisations that proactively manage and retain their own data are often in a stronger position than those relying entirely on platform reporting.

The businesses that perform best over the next decade are unlikely to be those with the most data available inside advertising platforms. Instead, they will be the businesses that build systems to collect, store, and analyse their own marketing data over time.
