A typical post picks up 2.4K interactions against 5.7M followers, an engagement rate of 0.043%. Measured over 161 original posts, its engagement rate beats 56% of 21,185 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 174K times each, and 1.40% of those impressions turn into an interaction. That is about 3.04% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 13.6 posts a day over the last 30 days, with activity on almost every day in the window. Most posts go out around 17:00 UTC, and Wednesday is the busiest day of the week. Of the 161 posts sampled, 99% carry an image or video. The account's strongest tracked post pulled 67K interactions, about 26x its own typical post.

Compared with accounts its own size

Science girl's engagement rate beats 56% of the tracked X accounts closest to it in follower count (21,185 accounts, accounts of similar size (decile 10 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 56% 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 0.043%, Science girl sits above the 25th percentile of the 211,892 accounts in this comparison. That places it in the below the median band, which runs 0.025% to 0.146%.

Engagement rate as a share of followers, across the 211,892 accounts we have scanned enough to measure. The axis is logarithmic, because the top and bottom of this population are about 22,457 times apart and a linear axis would flatten everything below the median into a single point.

Posting timing

This account posts most often around 17:00 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.

Engagement by hour posted, UTCTwenty-four bars, one per UTC hour. Each bar shows how posts published in that hour compare with their own authors' median engagement. Bars above the centre line ran higher than the median, bars below ran lower. A marker flags Busiest hour: 17:00 UTC.

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.

This account's posting mix compared with catalog-wide effects
FormatThis accountCatalog effect95% intervalAccounts behind it
Image or video99% of posts+111%+108% to +115%34K

  • 99% 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.
  • 2% 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 157 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.

Reading these numbers

A typical post picks up 2.4K interactions against 5.7M followers, an engagement rate of 0.043%. Measured over 161 original posts, its engagement rate beats 56% of 21,185 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 174K times each, and 1.40% of those impressions turn into an interaction.

Posting runs at about 13.6 posts a day over the last 30 days, with activity on almost every day in the window. Most posts go out around 17:00 UTC, and Wednesday is the busiest day of the week.

What is Science girl's engagement rate on X?
Science girl (@sciencegirl) has an engagement rate of 0.043%, based on the median interactions across 161 original posts from the last 30 days against 5,727,663 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
Is that a good engagement rate?
At 0.043%, Science girl sits above the 25th percentile of the 211,892 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 @sciencegirl have real engagement?
Its engagement rate beats 56% of the tracked X accounts closest to it in follower count (21,185 accounts), which puts it in the middle of its size range group. Ranking inside a size band matters because engagement rate falls as accounts grow, so a raw rate would mostly re-measure the follower count. It is a starting point for a look at follower quality, not a verdict on it.
When does @sciencegirl post?
Most posts go out around 17:00 UTC, and Wednesday is its busiest day, at roughly 13.63 posts per day across the measured window.

Keep going
