A typical post picks up 21K interactions against 1.4M followers, an engagement rate of 1.55%. Measured over 102 original posts, its engagement rate beats 99% of 3,774 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 290K times each, and 7.31% of those impressions turn into an interaction. That is about 21.1% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 4.4 posts a day over the last 30 days, with activity on almost every day in the window. Most posts go out around 03:00 UTC, and Friday is the busiest day of the week. Of the 102 posts sampled, 83% carry an image or video and 89% link out. The account's strongest tracked post pulled 113K interactions, about 5.3x its own typical post. Recurring topics include #cortis, #코르티스, #greengreen_playextended.

Compared with accounts its own size

CORTIS's engagement rate beats 99% of the tracked X accounts closest to it in follower count (3,774 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 97% 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 1.55%, CORTIS sits above the 75th percentile of the 36,521 accounts in this comparison. That places it in the top 25% band, which runs 0.434% to 2.10%.

Engagement rate as a share of followers, across the 36,521 accounts we have scanned enough to measure. The axis is logarithmic, because the top and bottom of this population are about 107,166 times apart and a linear axis would flatten everything below the median into a single point.

Posting timing

This account posts most often around 03:00 UTC, and Friday 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 CORTIS's engagement rate on X?
CORTIS (@cortis_bighit) has an engagement rate of 1.55%, based on the median interactions across 102 original posts from the last 30 days against 1,372,038 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
Is that a good engagement rate?
At 1.55%, CORTIS sits above the 75th percentile of the 36,521 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.

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 @cortis_bighit post?
Most posts go out around 03:00 UTC, and Friday is its busiest day, at roughly 4.4 posts per day across the measured window.
