Engagement
A typical post picks up 1.0K interactions against 405K followers, an engagement rate of 0.255%. Measured over 18 original posts, its engagement rate beats 85% 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 157K times each, and 0.659% of those impressions turn into an interaction. That is about 38.8% of the follower count, which is the gap between an audience on paper and an audience in a timeline.
Measured over 18 original posts from a 30-day window, last computed on September 27, 2026. Recurring tags: #47news, #mdl, #東奥日報.
