CU Boulder 🦬 engagement report
@CUBoulder - 91K followers on X
Measured over 20 original posts from a 30-day window, last computed on September 22, 2026.
Engagement
A typical post picks up 6 interactions against 91K followers, an engagement rate of 0.007%. Measured over 20 original posts, its engagement rate beats 14% of 20,444 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 2.4K times each, and 0.253% of those impressions turn into an interaction. That is about 2.61% 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 60% of days. Most posts go out around 16:00 UTC, and Monday is the busiest day of the week. Of the 20 posts sampled, 65% carry an image or video and 65% link out. The account's strongest tracked post pulled 273 interactions, about 46x its own typical post. Recurring topics include #gobuffs, #foreverfolsom, #skobuffs.

Compared with accounts its own size
CU Boulder 🦬's engagement rate beats 14% of the tracked X accounts closest to it in follower count (20,444 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 13% 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 0.007%, CU Boulder 🦬 sits above the 10th percentile of the 204,956 accounts in this comparison. That places it in the bottom 25% band, which runs below 0.024%.

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.

Formats this account uses
Its own posting mix on the left, and what each of those formats does across every account we track on the right. Only formats where the effect clears our publish test appear here, so an empty row is a format we could not measure rather than one that does nothing.
| Format | This account | Catalog effect | 95% interval | Accounts behind it |
|---|---|---|---|---|
| Image or video | 65% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 65% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | no effect | -2% to -1% | 42K |
- 65% of this account's sampled posts carry an image or video. Across the catalog, posts with an image or video run 111% above the same accounts' other posts.
- 65% of its posts carry a link off X. Across the catalog, posts with an outbound link run 41% below the same accounts' other posts, so a large share of this account's output sits in the weakest bucket we measure.
- Its average post runs 232 characters, which falls in the 180 - 280 characters band. Across the catalog, posts of 180 to 280 characters match the same accounts' other posts almost exactly.
These are catalog-wide differences applied to this account's own posting mix, not a measurement of how each format performs for this account specifically. We keep one median per account, not one per format per account, so the second thing is not something this data can tell you.

- What is CU Boulder 🦬's engagement rate on X?
- CU Boulder 🦬 (@CUBoulder) has an engagement rate of 0.007%, based on the median interactions across 20 original posts from the last 30 days against 90,644 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.007%, CU Boulder 🦬 sits above the 10th percentile of the 204,956 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 @CUBoulder have real engagement?
- Its engagement rate beats 14% of the tracked X accounts closest to it in follower count (20,444 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 @CUBoulder 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.
