A typical post picks up 16 interactions against 514K followers, an engagement rate of 0.003%. Measured over 10 original posts, its engagement rate beats 17% of 3,882 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 7.4K times each, and 0.208% of those impressions turn into an interaction. That is about 1.45% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.33 posts a day over the last 30 days, though only 10% of days saw any activity at all. Most posts go out around 18:00 UTC, and Saturday is the busiest day of the week. Of the 10 posts sampled, 20% carry an image or video and 100% link out. The account's strongest tracked post pulled 647 interactions, about 40x its own typical post.

Compared with accounts its own size

Chemistry News's engagement rate beats 17% of the tracked X accounts closest to it in follower count (3,882 accounts, accounts of similar size (decile 7 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 17% 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 0.003%, Chemistry News sits above the 10th percentile of the 37,582 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 37,582 accounts we have scanned enough to measure. The axis is logarithmic, because the top and bottom of this population are about 105,409 times apart and a linear axis would flatten everything below the median into a single point.

Posting timing

This account posts most often around 18:00 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 16 interactions against 514K followers, an engagement rate of 0.003%. Measured over 10 original posts, its engagement rate beats 17% of 3,882 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 7.4K times each, and 0.208% of those impressions turn into an interaction. That is about 1.45% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.33 posts a day over the last 30 days, though only 10% of days saw any activity at all. Most posts go out around 18:00 UTC, and Saturday is the busiest day of the week. Of the 10 posts sampled, 20% carry an image or video and 100% link out. The account's strongest tracked post pulled 647 interactions, about 40x its own typical post.

What is Chemistry News's engagement rate on X?
Chemistry News (@ChemistryNews) has an engagement rate of 0.003%, based on the median interactions across 10 original posts from the last 30 days against 514,138 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
Is that a good engagement rate?
At 0.003%, Chemistry News sits above the 10th percentile of the 37,582 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 @ChemistryNews have real engagement?
Its engagement rate beats 17% of the tracked X accounts closest to it in follower count (3,882 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 @ChemistryNews post?
Most posts go out around 18:00 UTC, and Saturday is its busiest day, at roughly 0.33 posts per day across the measured window.
