Measured over 41 original posts, its engagement rate beats 95% of 3,739 tracked accounts of a similar size.

Posts are seen about 592K times each, and 1.39% of those impressions turn into an interaction. That is about 20.2% of the follower count, which is the gap between an audience on paper and an audience in a timeline.
