Google Ads Lowers Minimum Active Users to 100 for Search and YouTube

Policy Change Overview

Google Ads just lowered the minimum audience size requirement for Search Network and YouTube to 100 active users within the last 30 days. This marks a significant shift from the previous 1,000-user threshold. The policy now aligns all audience segment types, including remarketing and customer lists, creating a uniform requirement of 100 users across the board. This change went into effect in December 2025.

Timeline of Changes

The reduction began in May 2024 when Customer Lists for Search campaigns dropped from 1,000 to 100 users. The Display Network followed suit earlier in 2025. The recent update extends this reduced threshold to Search and YouTube, indicating a coordinated effort by Google to simplify audience targeting.

Impact on Small Businesses and Advertisers

This update opens doors for smaller advertisers who previously struggled with the high user count required for targeted advertising. With a minimum of 100 users, campaigns can now leverage remarketing and Customer Match options even with limited traffic. This change could lead to an influx of smaller players in competitive spaces, potentially driving costs up as demand for premium inventory increases.

Context of Google Ads Evolution

Aligning this policy change with broader trends in Google Ads indicates a strategic shift to accommodate evolving search behaviors. As AI tools reshape user engagement, Google’s move to facilitate precise targeting for smaller segments reflects a need to adapt to these new paradigms. The introduction of enhanced data retention policies and support documentation highlights Google’s commitment to optimizing performance across channels.

Technical Mechanics and Best Practices

Active users are defined as individuals engaging with content within the last 30 days. Advertisers should utilize Audience Insights to verify segments now visible at the 100-user level. Incorporating dynamic remarketing strategies can enhance campaign effectiveness across Google’s networks.

Future Implications

Expect increased competition as smaller brands enter the fray, leveraging these new audience targeting capabilities. Over the next 6 to 12 months, monitor the impact on ad pricing and availability, as higher demand may lead to inflated costs. Advertisers must adapt quickly to capitalize on these changes while managing budget constraints.
