Measured over 55 original posts from a 30-day window, last computed on August 27, 2026.
Engagement
A typical post picks up 121 interactions against 933K followers, an engagement rate of 0.013%. Measured over 55 original posts, its engagement rate beats 38% of 3,809 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 21K times each, and 0.577% of those impressions turn into an interaction. That is about 2.25% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1.9 posts a day over the last 30 days, with activity on almost every day in the window. Most posts go out around 20:00 UTC, and Tuesday is the busiest day of the week. Of the 55 posts sampled, 96% carry an image or video. The account's strongest tracked post pulled 1.5K interactions, about 12x its own typical post.

Compared with accounts its own size
Universal-Sci's engagement rate beats 38% of the tracked X accounts closest to it in follower count (3,809 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 37% 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.

At 0.013%, Universal-Sci sits above the 25th percentile of the 36,960 accounts in this comparison. That places it in the below the median band, which runs 0.012% to 0.08%.

Posting timing
This account posts most often around 20:00 UTC, and Tuesday 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 121 interactions against 933K followers, an engagement rate of 0.013%. Measured over 55 original posts, its engagement rate beats 38% of 3,809 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 21K times each, and 0.577% of those impressions turn into an interaction. That is about 2.25% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1.9 posts a day over the last 30 days, with activity on almost every day in the window. Most posts go out around 20:00 UTC, and Tuesday is the busiest day of the week. Of the 55 posts sampled, 96% carry an image or video. The account's strongest tracked post pulled 1.5K interactions, about 12x its own typical post.
- What is Universal-Sci's engagement rate on X?
- Universal-Sci (@universal_sci) has an engagement rate of 0.013%, based on the median interactions across 55 original posts from the last 30 days against 932,924 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.013%, Universal-Sci sits above the 25th percentile of the 36,960 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 @universal_sci have real engagement?
- Its engagement rate beats 38% of the tracked X accounts closest to it in follower count (3,809 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 @universal_sci post?
- Most posts go out around 20:00 UTC, and Tuesday is its busiest day, at roughly 1.87 posts per day across the measured window.
