Engagement
A typical post picks up 1.6K interactions against 116K followers, an engagement rate of 1.39%. Measured over 9 original posts, its engagement rate beats 93% 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 39K times each, and 4.07% of those impressions turn into an interaction. That is about 33.8% of the follower count, which is the gap between an audience on paper and an audience in a timeline.
Measured over 9 original posts from a 30-day window, last computed on October 8, 2026.
