Engagement
A typical post picks up 17K interactions against 377K followers, an engagement rate of 4.66%. Measured over 44 original posts, its engagement rate beats 100% 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 285K times each, and 5.99% of those impressions turn into an interaction. That is about 75.5% of the follower count, which is the gap between an audience on paper and an audience in a timeline.
Measured over 44 original posts from a 30-day window, last computed on October 10, 2026. Recurring tags: #超特急, #ebidan, #超特急_エトランスフィーバー.
