Where do I find follower growth?

Follower growth is tracked over time, and can be viewed using the chart at the top of the Audience tab of a Profile or Account. 

Followers Over Time chart will display the last 7 data points we have for the account.

If the account was just added to the platform, this graph make take some time to populate. We can only track follower growth from the day/time that the account is added to our network.
