Engagement
A typical post picks up 614 interactions against 236K followers, an engagement rate of 0.26%. Measured over 10 original posts, its engagement rate beats 76% 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 39K times each, and 1.56% of those impressions turn into an interaction. That is about 16.7% of the follower count, which is the gap between an audience on paper and an audience in a timeline.
Measured over 10 original posts from a 30-day window, last computed on September 29, 2026. Recurring tags: #シンギュラボ, #ドラえもんを本気で作りたい.
