NASA History Office engagement report

Compared with accounts its own size

NASA History Office's engagement rate beats 80% of the tracked X accounts closest to it in follower count (3,882 accounts, accounts of similar size (decile 9 of 10)). A percentile is spread evenly by construction, so 50 really is the middle of that group and 90 really is its top tenth.

On engagement per impression rather than per follower it beats 85% of the same group. When those two numbers disagree, the gap is about how far its posts travel rather than how people react to them.

Where this sits in the catalog

At 0.165%, NASA History Office sits above the 50th percentile of the 37,459 accounts in this comparison. That places it in the above the median band, which runs 0.081% to 0.438%.

This ruler is the whole measured catalog, not a size-matched group: it shows where the raw rate falls across every account we can measure, all of which are large. For a like-for-like comparison, read the size-band percentile above instead. See how the bands are built

Posting timing

This account posts most often around 14:00 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.

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.

Reading these numbers

A typical post picks up 1.9K interactions against 1.2M followers, an engagement rate of 0.165%. Measured over 16 original posts, its engagement rate beats 80% of 3,882 tracked accounts of a similar size. Comparing inside a size band matters here: engagement rate falls as accounts grow, so a raw rate would mostly just re-measure the follower count. Posts are seen about 52K times each, and 3.66% of those impressions turn into an interaction. That is about 4.51% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1 post a day over the last 30 days, with activity on roughly 60% of days. Most posts go out around 14:00 UTC, and Wednesday is the busiest day of the week. Of the 16 posts sampled, 100% carry an image or video, 19% are part of a thread and 13% link out. The account's strongest tracked post pulled 19K interactions, about 9.6x its own typical post. Recurring topics include #dyk, #otd.

Is that a good engagement rate?

At 0.165%, NASA History Office sits above the 50th percentile of the 37,459 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.
