Sometimes you don’t want the full view that the advanced compare feature can give you. You only want to see how a certain other account is doing – follower growth, tweets per day etc. This is what the ‘quick compare’ feature is for:
From the followers graph scroll down to find the "Compare" option that allows you to compare the follower growth for two Twitter accounts for a period of up to three months.*
This way you can compare how your follower growth is compare to that of another user you are interested in.
You can also pick two other
users to compare them with each other and change the metric that
you’re comparing these users for: followers, following or tweets.
*This feature is only available for Premium users.
