A typical post picks up 4 interactions against 89K followers, an engagement rate of 0.004%. Measured over 18 original posts, its engagement rate beats 11% of 3,918 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 628 times each, and 0.637% of those impressions turn into an interaction. That is about 0.702% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1 post a day over the last 30 days, with activity on roughly 53% of days. Most posts go out around 16:00 UTC, and Monday is the busiest day of the week. Of the 18 posts sampled, 83% carry an image or video and 89% link out. The account's strongest tracked post pulled 11 interactions, about 2.8x its own typical post. Recurring topics include #climateweek, #marietharp.

Compared with accounts its own size

Columbia Climate School's engagement rate beats 11% of the tracked X accounts closest to it in follower count (3,918 accounts, accounts of similar size (decile 4 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 32% 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%, Columbia Climate School sits above the 10th percentile of the 37,996 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 37,996 accounts we have scanned enough to measure. The axis is logarithmic, because the top and bottom of this population are about 96,714 times apart and a linear axis would flatten everything below the median into a single point.

Posting timing

This account posts most often around 16:00 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.

A typical post picks up 4 interactions against 89K followers, an engagement rate of 0.004%. Measured over 18 original posts, its engagement rate beats 11% of 3,918 tracked accounts of a similar size.

What is Columbia Climate School's engagement rate on X?
Columbia Climate School (@columbiaclimate) has an engagement rate of 0.004%, based on the median interactions across 18 original posts from the last 30 days against 89,453 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
Is that a good engagement rate?
At 0.004%, Columbia Climate School sits above the 10th percentile of the 37,996 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 @columbiaclimate have real engagement?
Its engagement rate beats 11% of the tracked X accounts closest to it in follower count (3,918 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 @columbiaclimate post?
Most posts go out around 16:00 UTC, and Monday is its busiest day, at roughly 1.03 posts per day across the measured window.
