A typical post picks up 60 interactions against 511K followers, an engagement rate of 0.012%. Measured over 14 original posts, its engagement rate beats 32% of 3,862 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 29K times each, and 0.207% of those impressions turn into an interaction. That is about 5.73% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1.4 post a day over the last 30 days, though only 40% of days saw any activity at all. Most posts go out around 06:00 UTC, and Sunday is the busiest day of the week. Of the 14 posts sampled, 29% carry an image or video and 43% link out. The account's strongest tracked post pulled 7.6K interactions, about 126x its own typical post. Recurring topics include #fightgsr, #supergt, #ホロドリ.

Compared with accounts its own size

黒星紅白's engagement rate beats 32% of the tracked X accounts closest to it in follower count (3,862 accounts, accounts of similar size (decile 7 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 17% 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 0.012%, 黒星紅白 sits above the 10th percentile of the 37,350 accounts in this comparison. That places it in the bottom 25% band, which runs below 0.012%.

Engagement rate as a share of followers, across the 37,350 accounts we have scanned enough to measure. The axis is logarithmic, because the top and bottom of this population are about 106,576 times apart and a linear axis would flatten everything below the median into a single point.

Ranked by total interactions across everything we have tracked for this account, which is a longer history than the 30-day window the rates above use. The multiple compares each post to this account's own median.

Recurring topics

#fightgsr#supergt#ホロドリ#レーシングミク#初音ミク

The most frequent hashtags in the sampled posts. They describe what this account writes about; they are not a performance signal, and the catalog-wide breakdown on the hub shows how little hashtag count moves.

What is 黒星紅白's engagement rate on X?
黒星紅白 (@kuroboshi) has an engagement rate of 0.012%, based on the median interactions across 14 original posts from the last 30 days against 510,849 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
Is that a good engagement rate?
At 0.012%, 黒星紅白 sits above the 10th percentile of the 37,350 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.
Does @kuroboshi have real engagement?
Its engagement rate beats 32% of the tracked X accounts closest to it in follower count (3,862 accounts), which puts it in the middle of its size range group. Ranking inside a size band matters because engagement rate falls as accounts grow, so a raw rate would mostly re-measure the follower count. It is a starting point for a look at follower quality, not a verdict on it.
When does @kuroboshi post?
Most posts go out around 06:00 UTC, and Sunday is its busiest day, at roughly 1.4 posts per day across the measured window.
