British Library engagement report
@britishlibrary - 1.6M followers on X
Measured over 2 original posts from a 30-day window, last computed on October 25, 2026.
Engagement
Early reading. We have captured 2 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 12 interactions against 1.6M followers, an engagement rate of 0.001%. Posts are seen about 2.6K times each, and 0.46% of those impressions turn into an interaction. That is about 0.162% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.13 posts a day over the last 30 days, though only 13% of days saw any activity at all. Most posts go out around 10:00 UTC, and Tuesday is the busiest day of the week. Of the 2 posts sampled, 100% carry an image or video and 100% link out. The account's strongest tracked post pulled 664 interactions, about 55x its own typical post. Only 2 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.

Posting timing
This account posts most often around 10:00 UTC, and Tuesday 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 | 100% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | +15% | +14% to +16% | 32K |
- 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.
- 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 425 characters, which falls in the over 280 characters band. Across the catalog, posts over 280 characters run 15% above 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.

Last night we were thrilled to host an event celebrating one of Agatha Christie’s finest novels, The Seven Dials Mystery from 1929, to celebrate its upcoming @NetflixUK adaptation. To talk about the making of this hotly-anticipated release, we welcomed cast members Mia McKenna Bruce, Helena Bonham Carter and Martin Freeman, director and executive producer Chris Sweeney and writer and executive producer Chris Chibnall. This discussion was particularly special, ahead of our own major exhibition exploring the life and works of Agatha Christie in autumn 2026. We’re thrilled to be partnering with Netflix on these exciting literary conversations, continuing the momentum from our recent events with the director and cast of The Thursday Murder Club and Frankenstein.

- Is that a good engagement rate?
- At 0.001%, British Library sits below the 10th percentile of the 204,798 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.
