Science News engagement report
@ScienceNews - 5.3M followers on X
Measured over 189 original posts from a 30-day window, last computed on August 31, 2026.
Engagement
A typical post picks up 30 interactions against 5.3M followers, an engagement rate of 0.001%. Measured over 189 original posts, its engagement rate beats 15% of 3,716 tracked accounts of a similar size. That is a reason to look at how the audience behaves - reply depth, saves, whether the followers are recent - rather than a conclusion about it on its own. Posts are seen about 25K times each, and 0.122% of those impressions turn into an interaction. That is about 0.461% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 6.3 posts a day over the last 30 days, with activity on roughly 60% of days. Most posts go out around 15:00 UTC, and Saturday is the busiest day of the week. Of the 189 posts sampled, 100% link out. The account's strongest tracked post pulled 9.5K interactions, about 316x its own typical post.

Compared with accounts its own size
Science News's engagement rate beats 15% of the tracked X accounts closest to it in follower count (3,716 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 11% 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 0.001%, Science News sits below the 10th percentile of the 36,134 accounts in this comparison. That places it in the bottom 25% band, which runs below 0.012%.

Posting timing
This account posts most often around 15:00 UTC, and Saturday 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.

Reading these numbers
A typical post picks up 30 interactions against 5.3M followers, an engagement rate of 0.001%. Measured over 189 original posts, its engagement rate beats 15% of 3,716 tracked accounts of a similar size. That is a reason to look at how the audience behaves - reply depth, saves, whether the followers are recent - rather than a conclusion about it on its own. Posts are seen about 25K times each, and 0.122% of those impressions turn into an interaction. That is about 0.461% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 6.3 posts a day over the last 30 days, with activity on roughly 60% of days. Most posts go out around 15:00 UTC, and Saturday is the busiest day of the week.

- What is Science News's engagement rate on X?
- Science News (@ScienceNews) has an engagement rate of 0.001%, based on the median interactions across 189 original posts from the last 30 days against 5,338,676 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.001%, Science News sits below the 10th percentile of the 36,134 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 @ScienceNews have real engagement?
- Its engagement rate beats 15% of the tracked X accounts closest to it in follower count (3,716 accounts), which puts it in the bottom quarter for its size 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 @ScienceNews post?
- Most posts go out around 15:00 UTC, and Saturday is its busiest day, at roughly 6.3 posts per day across the measured window.
