City of Boulder engagement report
@bouldercolorado - 90K followers on X
Measured over 16 original posts from a 30-day window, last computed on August 28, 2026.
Engagement
A typical post picks up 2 interactions against 90K followers, an engagement rate of 0.002%. Measured over 16 original posts, its engagement rate beats 6% of 3,954 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 1.7K times each, and 0.119% of those impressions turn into an interaction. That is about 1.85% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.57 post a day over the last 30 days, with activity on roughly 50% of days. Most posts go out around 19:00 UTC, and Tuesday is the busiest day of the week. Of the 16 posts sampled, 94% carry an image or video and 100% link out. The account's strongest tracked post pulled 20 interactions, about 10x its own typical post.

Compared with accounts its own size
City of Boulder's engagement rate beats 6% of the tracked X accounts closest to it in follower count (3,954 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 7% 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.

Posting timing
This account posts most often around 19:00 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.

If you've walked the path over Boulder Creek near Scott Carpenter Park recently, you may have noticed it looking a little different. We fully reconstructed the bridge earlier this spring — restoring it to safe, sound condition for the thousands who cross it every year. https://t.co/wWsId1Vxes

Meet Broom Bear! 🐻🧹 Boulder's first fully electric street sweeper is now in service. Heavy-duty vehicles like this are among the most fuel-intensive we operate, so swapping to electric has an outsized impact on local air quality and emissions.

- What is City of Boulder's engagement rate on X?
- City of Boulder (@bouldercolorado) has an engagement rate of 0.002%, based on the median interactions across 16 original posts from the last 30 days against 90,381 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.002%, City of Boulder sits above the 10th percentile of the 38,255 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 @bouldercolorado have real engagement?
- Its engagement rate beats 6% of the tracked X accounts closest to it in follower count (3,954 accounts), which puts it in the bottom 10% 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 @bouldercolorado post?
- Most posts go out around 19:00 UTC, and Tuesday is its busiest day, at roughly 0.57 posts per day across the measured window.
