A typical post picks up 1.8K interactions against 144K followers, an engagement rate of 1.23%. Measured over 21 original posts, its engagement rate beats 91% of 15,519 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 24K times each, and 7.50% of those impressions turn into an interaction. That is about 16.4% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.73 post a day over the last 30 days, with activity on roughly 47% of days. Most posts go out around 09:00 UTC, and Sunday is the busiest day of the week. Of the 21 posts sampled, 81% carry an image or video and 100% link out. The account's strongest tracked post pulled 4.6K interactions, about 2.6x its own typical post. Recurring topics include #小島凪紗, #櫻坂46こち星, #櫻坂46.

Compared with accounts its own size

櫻坂46こちら有楽町星空放送局's engagement rate beats 91% of the tracked X accounts closest to it in follower count (15,519 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 93% 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 1.23%, 櫻坂46こちら有楽町星空放送局 sits above the 75th percentile of the 157,374 accounts in this comparison. That places it in the top 25% band, which runs 0.604% to 2.32%.

Engagement rate as a share of followers, across the 157,374 accounts we have scanned enough to measure. The axis is logarithmic, because the top and bottom of this population are about 26,055 times apart and a linear axis would flatten everything below the median into a single point.

Posting timing

This account posts most often around 09:00 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: 09:00 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 video81% of posts+111%+108% to +115%34K
Outbound link100% of posts-41%-42% to -40%32K
Typical length-no effect-2% to -1%42K
  • 81% 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.
  • 100% 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 184 characters, which falls in the 180 - 280 characters band. Across the catalog, posts of 180 to 280 characters match the same accounts' other posts almost exactly.

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 櫻坂46こちら有楽町星空放送局's engagement rate on X?
櫻坂46こちら有楽町星空放送局 (@kochihoshi) has an engagement rate of 1.23%, based on the median interactions across 21 original posts from the last 30 days against 144,237 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
Is that a good engagement rate?
At 1.23%, 櫻坂46こちら有楽町星空放送局 sits above the 75th percentile of the 157,374 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 @kochihoshi have real engagement?
Its engagement rate beats 91% of the tracked X accounts closest to it in follower count (15,519 accounts), which puts it in the top 10% 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 @kochihoshi post?
Most posts go out around 09:00 UTC, and Sunday is its busiest day, at roughly 0.73 posts per day across the measured window.
