Engagement
A typical post picks up 2 interactions against 113K followers, an engagement rate of 0.002%. Measured over 40 original posts, its engagement rate beats 7% of 20,444 tracked accounts of a similar size. That is a reason to look at how the audience behaves - reply depth, saves, whether the followers are recent - rather than a conclusion about it on its own. Posts are seen about 1.7K times each, and 0.12% of those impressions turn into an interaction. That is about 1.48% of the follower count, which is the gap between an audience on paper and an audience in a timeline.
