Which type of Custom Audience should I use?
All three types offer ways to directly target and remarket to the people you care about.
More on our policies for Custom Audiences.
My audience is showing as too small
To respect user privacy, your Custom Audience must be at least 100 Twitter users for it to be usable in your campaigns. CA's that fall short of this requirement will say “audience too small” in your Audiences tab, and cannot be used for campaign targeting.
Tips to increase your matched users:
- Lists: Add more user information to your .csv file and/or combine two smaller .csv files. Then, delete the "too small" CA from your Audiences tab and reupload the new, larger CA to reinitiate the matching process.
- Web Activity: Make sure your Web Pixel is correctly tracking, and your URL parameters for the CA are not too strict. The time it takes for your Web Activity audience to acquire 100 Twitter users depends on your web traffic.
What is "matching"?
When you create a Custom Audience, there's an initial processing period where the users on the Custom Audience. are "matched" by our systems to their Twitter @handle. This allows us to then serve your Promoted Tweets to their accounts.
It's possible that not all of the users on your Custom Audience are active Twitter users, which is why you might see a final Custom Audience size that is smaller than your original uploaded list.
Every Custom Audience is different, and until your list is processed and "matched", we cannot accurately estimate the match rate for an individual advertiser's Custom Audience. Once the Custom Audience is no longer showing as "Processing" in your Audiences Tab, the number of matched users for the Custom Audience will be shown. If there were less than 100 active Twitter users matched, it will show as "Audience too small". Unfortunately "too small" Custom Audiences will not be available for targeting in campaigns to respect user privacy.
Are the names of my Custom Audiences visible to anyone outside of my ads account?
Very rarely. People on Twitter are able to request their Twitter Archive which includes information about why they were targeted with particular ads. As part of this data, if they were included in a Custom Audience, they may have visibility into the audiences that qualified them for an ad impression. While people very rarely request and download this report, you may want to keep this in mind when naming your Custom Audiences.
