A typical post picks up 110 interactions against 2.6M followers, an engagement rate of 0.004%. Measured over 179 original posts, its engagement rate beats 34% of 3,758 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 26K times each, and 0.421% of those impressions turn into an interaction. That is about 1.02% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 6 posts a day over the last 30 days, with activity on roughly 57% of days. Most posts go out around 13:00 UTC, and Friday is the busiest day of the week. Of the 179 posts sampled, 54% carry an image or video and 24% link out. The account's strongest tracked post pulled 892 interactions, about 8.1x its own typical post.

Compared with accounts its own size

World and Science's engagement rate beats 34% of the tracked X accounts closest to it in follower count (3,758 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 35% 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 0.004%, World and Science sits above the 10th percentile of the 36,378 accounts in this comparison. That places it in the bottom 25% band, which runs below 0.012%.

Engagement rate as a share of followers, across the 36,378 accounts we have scanned enough to measure. The axis is logarithmic, because the top and bottom of this population are about 107,364 times apart and a linear axis would flatten everything below the median into a single point.

Posting timing

This account posts most often around 13:00 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.

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: 13:00 UTC.

Reading these numbers

A typical post picks up 110 interactions against 2.6M followers, an engagement rate of 0.004%. Measured over 179 original posts, its engagement rate beats 34% of 3,758 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 26K times each, and 0.421% of those impressions turn into an interaction. That is about 1.02% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 6 posts a day over the last 30 days, with activity on roughly 57% of days. Most posts go out around 13:00 UTC, and Friday is the busiest day of the week. Of the 179 posts sampled, 54% carry an image or video and 24% link out. The account's strongest tracked post pulled 892 interactions, about 8.1x its own typical post.

What is World and Science's engagement rate on X?
World and Science (@WorldAndScience) has an engagement rate of 0.004%, based on the median interactions across 179 original posts from the last 30 days against 2,568,244 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
Is that a good engagement rate?
At 0.004%, World and Science sits above the 10th percentile of the 36,378 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 @WorldAndScience have real engagement?
Its engagement rate beats 34% of the tracked X accounts closest to it in follower count (3,758 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 @WorldAndScience post?
Most posts go out around 13:00 UTC, and Friday is its busiest day, at roughly 6 posts per day across the measured window.
