Engagement
A typical post picks up 820 interactions against 237K followers, an engagement rate of 0.35%. Measured over 23 original posts, its engagement rate beats 80% of 20,444 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 37K times each, and 2.24% of those impressions turn into an interaction. That is about 15.5% of the follower count, which is the gap between an audience on paper and an audience in a timeline.
Measured over 23 original posts from a 30-day window, last computed on September 30, 2026.
