U.S. National Science Foundation engagement report
@NSF - 1.2M followers on X
Measured over 12 original posts from a 30-day window, last computed on October 25, 2026.
Engagement
A typical post picks up 62 interactions against 1.2M followers, an engagement rate of 0.005%. Posts are seen about 9.5K times each, and 0.656% of those impressions turn into an interaction. That is about 0.817% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.43 posts a day over the last 30 days, though only 30% of days saw any activity at all. Most posts go out around 16:00 UTC, and Tuesday is the busiest day of the week. Of the 12 posts sampled, 50% carry an image or video and 92% link out. The account's strongest tracked post pulled 800 interactions, about 13x its own typical post. Recurring topics include #nsffunded, #crew13.

Posting timing
This account posts most often around 16:00 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 | 50% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 92% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | +15% | +14% to +16% | 32K |
- 50% 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.
- 92% 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 336 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.

Ranked by total interactions across everything we have tracked for this account, which is a longer history than the 30-day window the rates above use. The multiple compares each post to this account's own median.
Recurring topics
The most frequent hashtags in the sampled posts. They describe what this account writes about; they are not a performance signal, and the catalog-wide breakdown on the hub shows how little hashtag count moves.

- What is U.S. National Science Foundation's engagement rate on X?
- U.S. National Science Foundation (@NSF) has an engagement rate of 0.005%, based on the median interactions across 12 original posts from the last 30 days against 1,165,613 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.005%, U.S. National Science Foundation sits above the 10th percentile of the 204,424 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.
- Does @NSF have real engagement?
- There is not yet enough sample to rank this account against others of its size.
- When does @NSF post?
- Most posts go out around 16:00 UTC, and Tuesday is its busiest day, at roughly 0.43 posts per day across the measured window.
