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.

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 | 67% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | no effect | -2% to -1% | 42K |
- 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

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
