楽天ブックス engagement report
@rakutenbooks - 379K followers on X
Measured over 55 original posts from a 30-day window, last computed on September 1, 2026.
Engagement
A typical post picks up 228 interactions against 379K followers, an engagement rate of 0.06%. Measured over 55 original posts, its engagement rate beats 44% of 3,899 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 24K times each, and 0.946% of those impressions turn into an interaction. That is about 6.36% 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, though only 33% of days saw any activity at all. Most posts go out around 07:00 UTC, and Tuesday is the busiest day of the week. Of the 55 posts sampled, 100% carry an image or video and 100% link out. The account's strongest tracked post pulled 19K interactions, about 83x its own typical post. Recurring topics include #owv, #travisjapan, #原因は自分にある.

Compared with accounts its own size
楽天ブックス's engagement rate beats 44% of the tracked X accounts closest to it in follower count (3,899 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 41% 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 0.06%, 楽天ブックス sits above the 25th percentile of the 37,856 accounts in this comparison. That places it in the below the median band, which runs 0.012% to 0.081%.

Posting timing
This account posts most often around 07:00 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.

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

Reading these numbers
A typical post picks up 228 interactions against 379K followers, an engagement rate of 0.06%. Measured over 55 original posts, its engagement rate beats 44% of 3,899 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 24K times each, and 0.946% of those impressions turn into an interaction. That is about 6.36% 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, though only 33% of days saw any activity at all. Most posts go out around 07:00 UTC, and Tuesday is the busiest day of the week. Of the 55 posts sampled, 100% carry an image or video and 100% link out. The account's strongest tracked post pulled 19K interactions, about 83x its own typical post.

- What is 楽天ブックス's engagement rate on X?
- 楽天ブックス (@rakutenbooks) has an engagement rate of 0.06%, based on the median interactions across 55 original posts from the last 30 days against 379,004 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.06%, 楽天ブックス sits above the 25th percentile of the 37,856 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 @rakutenbooks have real engagement?
- Its engagement rate beats 44% of the tracked X accounts closest to it in follower count (3,899 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 @rakutenbooks post?
- Most posts go out around 07:00 UTC, and Tuesday is its busiest day, at roughly 2.1 posts per day across the measured window.
