A typical post picks up 5.8K interactions against 1.2M followers, an engagement rate of 0.49%. Measured over 13 original posts, its engagement rate beats 93% of 3,774 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 208K times each, and 2.80% of those impressions turn into an interaction. That is about 17.5% of the follower count, which is the gap between an audience on paper and an audience in a timeline.

Measured over 13 original posts from a 30-day window, last computed on August 30, 2026. Recurring tags: #fビレッジ, #uuumday, #わほー.
