A typical post picks up 4.1K interactions against 1.4M followers, an engagement rate of 0.295%. Measured over 46 original posts, its engagement rate beats 86% of 1,003 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 378K times each, and 1.09% of those impressions turn into an interaction. That is about 27.2% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 2.1 posts a day over the last 30 days, with activity on roughly 67% of days. Most posts go out around 03:00 UTC, and Sunday is the busiest day of the week. Of the 46 posts sampled, 83% carry an image or video and 30% link out. The account's strongest tracked post pulled 69K interactions, about 17x 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 86% of the tracked X accounts closest to it in follower count (1,003 accounts, accounts of similar size (decile 6 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 53% 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 0.295%, ブルーアーカイブ公式 sits above the 50th percentile of the 10,326 accounts in this comparison. That places it in the above the median band, which runs 0.048% to 0.321%.

Engagement rate as a share of followers, across the 10,326 accounts we have scanned enough to measure. The axis is logarithmic, because the top and bottom of this population are about 442,521 times apart and a linear axis would flatten everything below the median into a single point.

Posting timing

This account posts most often around 03:00 UTC, and Sunday 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.

Engagement by hour posted, UTCTwenty-four bars, one per UTC hour. Each bar shows how posts published in that hour compare with their own authors' median engagement. Bars above the centre line ran higher than the median, bars below ran lower. A marker flags Busiest hour: 03:00 UTC.

Formats this account uses

Its own posting mix on the left, and what each of those formats does across every account we track on the right. Only formats where the effect clears our publish test appear here, so an empty row is a format we could not measure rather than one that does nothing.

This account's posting mix compared with catalog-wide effects
FormatThis accountCatalog effect95% intervalAccounts behind it
Image or video83% of posts+79%+73% to +85%5.8K
Outbound link30% of posts-49%-50% to -47%6.1K

  • 83% of this account's sampled posts carry an image or video. Across the catalog, posts with an image or video run 79% above the same accounts' other posts.
  • 30% of its posts carry a link off X. Across the catalog, posts with an outbound link run 49% below the same accounts' other posts.
  • Its average post runs 166 characters, which falls in the 80 - 180 characters band. Across the catalog, posts of 80 to 180 characters run 7% below the same accounts' other posts.

These are catalog-wide differences applied to this account's own posting mix, not a measurement of how each format performs for this account specifically. We keep one median per account, not one per format per account, so the second thing is not something this data can tell you.

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 0.295%, based on the median interactions across 46 original posts from the last 30 days against 1,391,111 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
Is that a good engagement rate?
At 0.295%, ブルーアーカイブ公式 sits above the 50th percentile of the 10,326 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 86% of the tracked X accounts closest to it in follower count (1,003 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 Sunday is its busiest day, at roughly 2.1 posts per day across the measured window.
