I recently learned that Google has made a significant change by lowering the minimum audience size requirement for its Ads platform to just 100 active users. This adjustment now makes it far easier for advertisers, both large and small, to harness the power of remarketing and customer lists without the previous constraints.
What’s new: Now, advertisers can utilize audience segments with as few as 100 users across platforms like Search, Display, and YouTube. This includes both remarketing lists and customer lists. Excitingly, this same 100-user limit also applies to Audience Insights, slashing the previous threshold from 1,000.

Catch up: The shift toward these smaller audience thresholds began in May. At that time, Google had already reduced the minimum user requirement for Customer Lists in Search campaigns from 1,000 to just 100 users. This marks a clear trend towards making audience targeting more inclusive.
Why this matters: Smaller accounts and niche advertisers now have the opportunity to implement audience strategies that were once unattainable due to those larger size thresholds. By bridging this gap, Google removes a longstanding barrier to advanced targeting and personalization within Ads.

What to watch: I’m curious to see how advertisers will leverage these more precise, smaller segments and whether performance or privacy safeguards will evolve to align with this broader access.
First seen: This update first caught the eye of Web Marketing Consultant, Dario Zannoni, who shared the news on LinkedIn.
Bottom line: By reducing audience size limits to 100 users everywhere, Google paves the way for a wider array of advertisers to access advanced audience targeting options.
