Engagement
A typical post picks up 13K interactions against 13M followers, an engagement rate of 0.101%. Measured over 10 original posts, its engagement rate beats 91% of 982 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 240K times each, and 5.32% of those impressions turn into an interaction. That is about 1.90% of the follower count, which is the gap between an audience on paper and an audience in a timeline.
Measured over 10 original posts from a 30-day window, last computed on August 22, 2026. Recurring tags: #bt21, #chimmy, #rj.
