A typical post picks up 5.9K interactions against 948K followers, an engagement rate of 0.627%. Measured over 42 original posts, its engagement rate beats 94% 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 184K times each, and 3.23% of those impressions turn into an interaction. That is about 19.4% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 2.3 posts a day over the last 30 days, with activity on roughly 63% of days. Most posts go out around 09:00 UTC, and Tuesday is the busiest day of the week. Of the 42 posts sampled, 62% carry an image or video and 64% link out. The account's strongest tracked post pulled 130K interactions, about 22x its own typical post. Recurring topics include #にじ甲2026, #推しナイン発表会, #pr.

Compared with accounts its own size

星川サラ🌟Sara Hoshikawa's engagement rate beats 94% of the tracked X accounts closest to it in follower count (3,774 accounts, accounts of similar size (decile 9 of 10)). A percentile is spread evenly by construction, so 50 really is the middle of that group and 90 really is its top tenth.

On engagement per impression rather than per follower it beats 82% of the same group. When those two numbers disagree, the gap is about how far its posts travel rather than how people react to them.

Where this sits in the catalog

At 0.627%, 星川サラ🌟Sara Hoshikawa sits above the 75th percentile of the 36,654 accounts in this comparison. That places it in the top 25% band, which runs 0.433% to 2.10%.

Engagement rate as a share of followers, across the 36,654 accounts we have scanned enough to measure. The axis is logarithmic, because the top and bottom of this population are about 106,977 times apart and a linear axis would flatten everything below the median into a single point.

Reading these numbers

A typical post picks up 5.9K interactions against 948K followers, an engagement rate of 0.627%. Measured over 42 original posts, its engagement rate beats 94% of 3,774 tracked accounts of a similar size.

That is about 19.4% of the follower count, which is the gap between an audience on paper and an audience in a timeline.

Ranking inside a size band matters because engagement rate falls as accounts grow, so a raw rate would mostly re-measure the follower count.
