ブルーアーカイブ公式 engagement report
@Blue_ArchiveJP - 1.4M followers on X
Measured over 71 original posts from a 30-day window, last computed on September 1, 2026.
Engagement
A typical post picks up 4.6K interactions against 1.4M followers, an engagement rate of 0.33%. Measured over 71 original posts, its engagement rate beats 89% of 3,809 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 397K times each, and 1.16% of those impressions turn into an interaction. That is about 28.5% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 3.4 posts a day over the last 30 days, with activity on almost every day in the window. Most posts go out around 03:00 UTC, and Tuesday is the busiest day of the week. Of the 71 posts sampled, 77% carry an image or video and 34% link out. The account's strongest tracked post pulled 81K interactions, about 18x its own typical post. Recurring topics include #ブルアカ, #ブルアカらじお, #ブルーアーカイブ.

Compared with accounts its own size
ブルーアーカイブ公式's engagement rate beats 89% of the tracked X accounts closest to it in follower count (3,809 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 55% 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 0.33%, ブルーアーカイブ公式 sits above the 50th percentile of the 36,960 accounts in this comparison. That places it in the above the median band, which runs 0.08% to 0.435%.

Posting timing
This account posts most often around 03:00 UTC, and Tuesday is its busiest day of the week. The bars below are the catalog-wide pattern, with this account's own busiest slot marked. They do not show how this account performs at each hour: we keep one aggregate per account, not one per hour, so that measurement does not exist in our data.

【生徒紹介】 ダイビング部の副部長を務めるコトネさん。 かなり視力が低く、普段から度数の高いメガネをかけているコトネさんですが、視力の代わりに聴力と直感がずば抜けているそうで、水中での視界が悪いときは、聴力を頼りに部員を先導してくれるそうです! 「目、あんまり良くないから……顔を覚えるのに時間がかかるかも」 #ブルアカ

- What is ブルーアーカイブ公式's engagement rate on X?
- ブルーアーカイブ公式 (@Blue_ArchiveJP) has an engagement rate of 0.33%, based on the median interactions across 71 original posts from the last 30 days against 1,392,234 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.33%, ブルーアーカイブ公式 sits above the 50th percentile of the 36,960 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 @Blue_ArchiveJP have real engagement?
- Its engagement rate beats 89% of the tracked X accounts closest to it in follower count (3,809 accounts), which puts it in the top quarter for its size 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 @Blue_ArchiveJP post?
- Most posts go out around 03:00 UTC, and Tuesday is its busiest day, at roughly 3.43 posts per day across the measured window.
