A typical post picks up 1.1K interactions against 658K followers, an engagement rate of 0.166%. Measured over 44 original posts, its engagement rate beats 78% of 4,199 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 216K times each, and 0.506% of those impressions turn into an interaction. That is about 32.8% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 3.2 posts a day over the last 30 days, with activity on almost every day in the window. Most posts go out around 10:00 UTC, and Saturday is the busiest day of the week. Of the 44 posts sampled, 59% carry an image or video and 48% link out. The account's strongest tracked post pulled 462K interactions, about 423x its own typical post. Recurring topics include #せいや, #tver, #x秒後の新世界.

Compared with accounts its own size

霜降り明星 せいや🕙's engagement rate beats 78% of the tracked X accounts closest to it in follower count (4,199 accounts, accounts of similar size (decile 8 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 34% 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.

At 0.166%, 霜降り明星 せいや🕙 sits above the 50th percentile of the 40,619 accounts in this comparison. That places it in the above the median band, which runs 0.082% to 0.443%.

Engagement rate as a share of followers, across the 40,619 accounts we have scanned enough to measure. The axis is logarithmic, because the top and bottom of this population are about 91,008 times apart and a linear axis would flatten everything below the median into a single point.

Is that a good engagement rate?
At 0.166%, 霜降り明星 せいや🕙 sits above the 50th percentile of the 40,619 accounts in this comparison. Those comparison accounts are all large ones, because our scanning cadence is weighted towards big accounts, so this is a ranking among peers of similar scale rather than a ranking across X.
