Engagement
A typical post picks up 1.4K interactions against 709K followers, an engagement rate of 0.196%. Measured over 15 original posts, its engagement rate beats 81% 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 117K times each, and 1.19% of those impressions turn into an interaction. That is about 16.5% of the follower count, which is the gap between an audience on paper and an audience in a timeline.
Measured over 15 original posts from a 30-day window, last computed on October 2, 2026.
