Maximum source audience size
Not on the Facebook side. The more users and values that you share with us, the better we're able to optimise.
However, if you upload a list that's very large, your browser could run out of time or memory before the upload is complete. Two factors determine the size of your file:
- The number of people.
- The number of data columns per person.
Increasing either of these increases the chances of your browser not being able to complete the upload. If you do run into this problem, try reducing the number of rows with "0" values. If that isn't enough, try removing all "0" value rows, then the lowest value rows and so on until the file uploads successfully.
