Earlier this year, Google lowered the size of your data segment customer lists to 100 active visitors for the Google Display Network. Now, Google updated that to also be 100 active visitors for the Search Network and YouTube.
Google updated it to read:
- Google Search Network must have a minimum of 100 active visitors or users within the last 30 days. Customer lists also have the same eligibility.
- YouTube must have a minimum of 100 active visitors or users within the last 30 days. Customer lists also have the same eligibility.
Previously it read:
- Google Search Network must have a minimum of 1,000 active visitors or users within the last 30 days, unless it is a customer list. Customer lists must have a minimum of 100 active visitors or users within the last 30 days.
- YouTube must have a minimum of 1,000 active visitors or users within the last 30 days, unless it is a customer list. Customer lists must have a minimum of 100 active visitors or users within the last 30 days.
This change was spotted by Dario Zannoni who wrote on LinkedIn and X, "Google drops audience limits to 100 users for all networks and audience types." He added:
Back in May this year, it was found that Google had reduced the minimum number of users required to use Customer Lists in Search campaigns (from 1000 to 100).Since then, Google has continued gradually lowering these size limits across the different networks and audience types, seemingly aiming to harmonize the requirements and make audience lists easier to use even for smaller accounts.
According to the most recent support pages on "audience segments," the minimum Audience Size Limit has now been reduced to just 100 active users for ALL networks and ALL segment types:
- Across all 3 networks: Display, Search, and YouTube
- Across all segment types, including Remarketing Lists, and Customer Lists
At the same time, the threshold for a segment to appear in Audience Insights has been lowered from 1,000 to 100 users.The help page (link in the first comment) appears to have been updated very recently. It now also includes more detailed information, including ad policies and troubleshooting tips, so I recommend checking it out if you work with user segments.
Google also added a new section in the blue area at the top that says, "New advertising policies" with a lot more details. Plus Google expanded the "Active users" section and added a section on "Troubleshoot audience size discrepancies and list population."
