Engagement
A typical post picks up 113 interactions against 2.6M followers, an engagement rate of 0.004%. Posts are seen about 19K times each, and 0.586% of those impressions turn into an interaction. That is about 0.752% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 6.8 posts a day over the last 30 days, with activity on almost every day in the window. Most posts go out around 18:00 UTC, and Friday is the busiest day of the week. Of the 202 posts sampled, 55% carry an image or video and 24% link out. The account's strongest tracked post pulled 892 interactions, about 7.9x its own typical post.

Posting timing
This account posts most often around 18:00 UTC, and Friday 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 | 55% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 24% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | -3% | -3% to -2% | 54K |
- 55% 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.
- 24% of its posts carry a link off X. Across the catalog, posts with an outbound link run 41% below the same accounts' other posts.
- Its average post runs 179 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.
