A typical post picks up 5.3K interactions against 1.1M followers, an engagement rate of 0.498%. Measured over 18 original posts, its engagement rate beats 93% of 3,791 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 277K times each, and 1.91% of those impressions turn into an interaction. That is about 26.1% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1.9 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 Saturday is the busiest day of the week. Of the 18 posts sampled, 78% carry an image or video, 33% are part of a thread and 33% link out. The account's strongest tracked post pulled 96K interactions, about 18x its own typical post. Recurring topics include #ももこ, #c108, #c108_cos.

Compared with accounts its own size

ももこ's engagement rate beats 93% of the tracked X accounts closest to it in follower count (3,791 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 69% 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 0.498%, ももこ sits above the 75th percentile of the 36,654 accounts in this comparison. That places it in the top 25% band, which runs 0.433% to 2.10%.

Engagement rate as a share of followers, across the 36,654 accounts we have scanned enough to measure. The axis is logarithmic, because the top and bottom of this population are about 106,977 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 Saturday 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 ももこ's engagement rate on X?
ももこ (@momoco_haru) has an engagement rate of 0.498%, based on the median interactions across 18 original posts from the last 30 days against 1,062,058 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
Is that a good engagement rate?
At 0.498%, ももこ sits above the 75th percentile of the 36,654 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 @momoco_haru have real engagement?
Its engagement rate beats 93% of the tracked X accounts closest to it in follower count (3,791 accounts), which puts it in the top 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 @momoco_haru post?
