Engagement
A typical post picks up 1.3K interactions against 315K followers, an engagement rate of 0.427%. Measured over 17 original posts, its engagement rate beats 83% 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 83K times each, and 1.62% of those impressions turn into an interaction. That is about 26.3% of the follower count, which is the gap between an audience on paper and an audience in a timeline.
Measured over 17 original posts from a 30-day window, last computed on October 15, 2026. Recurring tags: #島田洋一, #高市早苗, #nhk_news.
