Eric Berger engagement report
@SciGuySpace - 437K followers on X
Measured over 19 original posts from a 30-day window, last computed on August 30, 2026.
Engagement
A typical post picks up 901 interactions against 437K followers, an engagement rate of 0.206%. Measured over 19 original posts, its engagement rate beats 79% of 3,739 tracked accounts of a similar size. Comparing inside a size band matters here: engagement rate falls as accounts grow, so a raw rate would mostly just re-measure the follower count. Posts are seen about 64K times each, and 1.40% of those impressions turn into an interaction. That is about 14.7% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1.5 posts a day over the last 30 days, with activity on roughly 53% of days. Most posts go out around 14:00 UTC, and Monday is the busiest day of the week. Of the 19 posts sampled, 26% carry an image or video and 53% link out. The account's strongest tracked post pulled 8.1K interactions, about 9.0x its own typical post.

Compared with accounts its own size
Eric Berger's engagement rate beats 79% of the tracked X accounts closest to it in follower count (3,739 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 60% 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 0.206%, Eric Berger sits above the 50th percentile of the 36,261 accounts in this comparison. That places it in the above the median band, which runs 0.08% to 0.431%.

Posting timing
This account posts most often around 14:00 UTC, and Monday 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.

- What is Eric Berger's engagement rate on X?
- Eric Berger (@SciGuySpace) has an engagement rate of 0.206%, based on the median interactions across 19 original posts from the last 30 days against 437,188 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.206%, Eric Berger sits above the 50th percentile of the 36,261 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 @SciGuySpace have real engagement?
- Its engagement rate beats 79% of the tracked X accounts closest to it in follower count (3,739 accounts), which puts it in the top 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 @SciGuySpace post?
- Most posts go out around 14:00 UTC, and Monday is its busiest day, at roughly 1.47 posts per day across the measured window.
