西友 SEIYU engagement report
@Seiyu_Japan - 254K followers on X
Measured over 51 original posts from a 30-day window, last computed on September 9, 2026.
Engagement
A typical post picks up 27 interactions against 254K followers, an engagement rate of 0.011%. Measured over 51 original posts, its engagement rate beats 26% of 6,874 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 8.1K times each, and 0.332% of those impressions turn into an interaction. That is about 3.20% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1.7 posts a day over the last 30 days, with activity on almost every day in the window. Most posts go out around 23:00 UTC, and Thursday is the busiest day of the week. Of the 51 posts sampled, 100% carry an image or video and 82% link out. The account's strongest tracked post pulled 1.1K interactions, about 40x its own typical post. Recurring topics include #楽天ポイント, #チラシ, #トライアル.

Compared with accounts its own size
西友 SEIYU's engagement rate beats 26% of the tracked X accounts closest to it in follower count (6,874 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 22% 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 0.011%, 西友 SEIYU sits above the 10th percentile of the 66,128 accounts in this comparison. That places it in the bottom 25% band, which runs below 0.016%.

Posting timing
This account posts most often around 23:00 UTC, and Thursday 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.

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.
| Format | This account | Catalog effect | 95% interval | Accounts behind it |
|---|---|---|---|---|
| Image or video | 100% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 82% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | -3% | -3% to -2% | 54K |
- 100% of this account's sampled posts carry an image or video. Across the catalog, posts with an image or video run 111% above the same accounts' other posts.
- 82% of its posts carry a link off X. Across the catalog, posts with an outbound link run 41% below the same accounts' other posts, so a large share of this account's output sits in the weakest bucket we measure.
- Its average post runs 178 characters, which falls in the 80 - 180 characters band. Across the catalog, posts of 80 to 180 characters run 3% 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 西友 SEIYU's engagement rate on X?
- 西友 SEIYU (@Seiyu_Japan) has an engagement rate of 0.011%, based on the median interactions across 51 original posts from the last 30 days against 254,397 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.011%, 西友 SEIYU sits above the 10th percentile of the 66,128 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 @Seiyu_Japan have real engagement?
- Its engagement rate beats 26% of the tracked X accounts closest to it in follower count (6,874 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 @Seiyu_Japan post?
- Most posts go out around 23:00 UTC, and Thursday is its busiest day, at roughly 1.73 posts per day across the measured window.
