Early reading. We have captured 5 original posts for this account, below the 8 we require before treating a median as settled. The numbers above describe what we have seen so far, not a finished profile of the account.

A typical post picks up 202 interactions against 527K followers, an engagement rate of 0.038%. Posts are seen about 33K times each, and 0.621% of those impressions turn into an interaction. That is about 6.17% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1.4 post a day over the last 30 days, though only 33% of days saw any activity at all. Most posts go out around 08:00 UTC, and Monday is the busiest day of the week. Of the 5 posts sampled, 60% carry an image or video and 40% link out. The account's strongest tracked post pulled 13K interactions, about 62x its own typical post. Recurring topics include #佐々木悠葵, #富山競輪, #共同通信社杯. Only 5 original posts have been captured so far, fewer than the 8 posts we want behind a median before treating it as settled. Read the figures above as an early measurement of this account, not as a finished profile of it.

Engagement rate as a share of followers, across the 204,798 accounts we have scanned enough to measure. The axis is logarithmic, because the top and bottom of this population are about 22,879 times apart and a linear axis would flatten everything below the median into a single point.

Posting timing

This account posts most often around 08:00 UTC, and Monday 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: 08:00 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 video60% of posts+111%+108% to +115%34K
Outbound link40% of posts-41%-42% to -40%32K
Typical length--3%-3% to -2%54K
  • 60% 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.
  • 40% 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 103 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.

    今日、大親友の天木じゅんちゃんがグラビアを卒業します🌸 ずっと前から分かっていたはずなのに、なぜかいまだに実感がわかない!! じゅんちゃんとはグラビアのことも、それ以外のことも、本当にたくさん語って、たくさん共有してきました。 びっくりするくらい純粋で、 私にはないものをたくさん持っていて、 近くにいる私も何度も刺激をもらったし、 じゅんちゃんのおかげで私のグラビア人生はとても豊かになったし、グラビアというお仕事を、もっと好きになれました🌱 一緒に過ごしてきた時間を思い返すと、本当に幸せな時間だったなぁって思う。。 こんな日が来るなんてな〜。 やっぱりちょっと寂しいけど、ここまで走り続けたじゅんちゃんを心から尊敬しています✨ グラビア卒業、本当におめでとう。 グラビアを卒業しても、 大親友なのは何も変わらないからね☺️ これからもたくさん笑って、たくさん語って、 いろんな時間を一緒に過ごしていこうね。 本当にお疲れさま。 そして、これからもよろしくね♡ じゅんちゃんがだいすきです!!
