Engagement
A typical post picks up 20K interactions against 874K followers, an engagement rate of 2.28%. Measured over 14 original posts, its engagement rate beats 99% of 20,182 tracked accounts of a similar size. Comparing inside a size band matters here: engagement rate falls as accounts grow, so a raw rate would mostly just re-measure the follower count. Posts are seen about 607K times each, and 3.26% of those impressions turn into an interaction. That is about 69.5% of the follower count, which is the gap between an audience on paper and an audience in a timeline.
