Engagement
A typical post picks up 2.3K interactions against 435K followers, an engagement rate of 0.529%. Measured over 38 original posts, its engagement rate beats 91% of 3,862 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 34K times each, and 6.83% of those impressions turn into an interaction. That is about 7.75% of the follower count, which is the gap between an audience on paper and an audience in a timeline.
Measured over 38 original posts from a 30-day window, last computed on August 30, 2026. Recurring tags: #セトグミ2026, #セト絵, #バターカップ.
