Engagement
A typical post picks up 7.9K interactions against 859K followers, an engagement rate of 0.918%. Measured over 21 original posts, its engagement rate beats 97% of 3,774 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 244K times each, and 3.23% of those impressions turn into an interaction. That is about 28.5% of the follower count, which is the gap between an audience on paper and an audience in a timeline.
