Google’s New 540-Day Customer Match Data Rule: What SEO Professionals Need to Know

In a significant move towards enhancing user privacy, Google has announced a new policy that will impose a 540-day cap on Customer Match list durations across its advertising platforms, effective April 7, 2025. This update is part of Google’s ongoing efforts to address privacy concerns and ensure that advertisers maintain current and relevant customer data.

The key points of this update include the introduction of a maximum duration of 540 days for Customer Match lists, which will automatically adjust existing lists that exceed this limit. This change will affect all Google Ads and Display & Video 360 platforms, requiring advertisers to rethink their data management strategies.

One of the most critical implications of this update is the potential impact on advertisers’ targeting strategies. As the new cap may lead to smaller list sizes over time, advertisers will need to implement regular data refresh protocols to keep their customer data current. This shift places more responsibility on advertisers to actively manage and refresh their customer data, which is essential for maintaining effective advertising campaigns.

The update reflects a broader trend towards privacy-focused advertising practices, emphasizing the need for marketers to prioritize data accuracy and freshness. SEO professionals should be aware of these changes, as they may necessitate adjustments in campaign management and targeting strategies.

As noted in the article, “Advertisers must adapt their targeting strategies as the new cap may lead to smaller list sizes over time,” highlighting the importance of proactive data management in the evolving landscape of digital advertising.
