That is about 5.31% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1.5 posts a day over the last 30 days, with activity on roughly 57% of days. Most posts go out around 21:00 UTC, and Wednesday is the busiest day of the week. Of the 18 posts sampled, 100% carry an image or video, 6% are part of a thread and 67% link out. The account's strongest tracked post pulled 12K interactions, about 7.7x its own typical post.

Engagement rate as a share of followers, across the 204,424 accounts we have scanned enough to measure. The axis is logarithmic, because the top and bottom of this population are about 22,888 times apart and a linear axis would flatten everything below the median into a single point.

Posting timing

This account posts most often around 21:00 UTC, and Wednesday 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: 21:00 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 video100% of posts+111%+108% to +115%34K

  • 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.
  • 67% 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 278 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.

    Look up tonight. The Moon will pass through Earth's shadow during a deep partial lunar eclipse visible from much of North and South America and parts of Europe and Africa. As the eclipse deepens, the Moon will appear tinged with shades of red and copper. https://t.co/dicZoGxbiZ

    🌕 Happy International Moon Day! On this day in 1969, Neil Armstrong took humanity's first steps on the Moon. Today, through the Artemis program, we're building on that legacy. Together, we're shaping the future of deep space exploration, one mission at a time. https://t.co/nV3Itask9w

    There’s a full Moon rising. The Harvest Moon is the full Moon that occurs closest to the fall equinox. This year, it's on Saturday, Sept. 26. As the Harvest Moon rises in the east shortly after sunset, Saturn will appear nearby. Take a moment to look up and enjoy the view. https://t.co/1Zd49EqJaY
