Phys.org engagement report
@physorg_com - 1.0M followers on X
Measured over 52 original posts from a 30-day window, last computed on August 31, 2026.
Engagement
A typical post picks up 40 interactions against 1.0M followers, an engagement rate of 0.004%. Measured over 52 original posts, its engagement rate beats 23% of 3,758 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 7.2K times each, and 0.558% of those impressions turn into an interaction. That is about 0.711% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 3.7 posts a day over the last 30 days, though only 23% of days saw any activity at all. Most posts go out around 14:00 UTC, and Wednesday is the busiest day of the week. Of the 52 posts sampled, 100% link out. The account's strongest tracked post pulled 191 interactions, about 4.8x its own typical post.

Compared with accounts its own size
Phys.org's engagement rate beats 23% of the tracked X accounts closest to it in follower count (3,758 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 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%, Phys.org 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%.

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

Ranked by total interactions across everything we have tracked for this account, which is a longer history than the 30-day window the rates above use. The multiple compares each post to this account's own median.

Reading these numbers
A typical post picks up 40 interactions against 1.0M followers, an engagement rate of 0.004%. Measured over 52 original posts, its engagement rate beats 23% of 3,758 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 7.2K times each, and 0.558% of those impressions turn into an interaction. That is about 0.711% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 3.7 posts a day over the last 30 days, though only 23% of days saw any activity at all. Most posts go out around 14:00 UTC, and Wednesday is the busiest day of the week. Of the 52 posts sampled, 100% link out. The account's strongest tracked post pulled 191 interactions, about 4.8x its own typical post.
- What is Phys.org's engagement rate on X?
- Phys.org (@physorg_com) has an engagement rate of 0.004%, based on the median interactions across 52 original posts from the last 30 days against 1,008,401 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.004%, Phys.org 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 @physorg_com have real engagement?
- Its engagement rate beats 23% of the tracked X accounts closest to it in follower count (3,758 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 @physorg_com post?
- Most posts go out around 14:00 UTC, and Wednesday is its busiest day, at roughly 3.7 posts per day across the measured window.
