CSIC engagement report
@CSIC - 926K followers on X
Measured over 56 original posts from a 30-day window, last computed on August 28, 2026.
Engagement
A typical post picks up 34 interactions against 926K followers, an engagement rate of 0.004%. Measured over 56 original posts, its engagement rate beats 23% of 3,739 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 6.1K times each, and 0.554% of those impressions turn into an interaction. That is about 0.663% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 2.8 posts a day over the last 30 days, with activity on almost every day in the window. Most posts go out around 09:00 UTC, and Thursday is the busiest day of the week. Of the 56 posts sampled, 95% carry an image or video, 5% are part of a thread and 73% link out. The account's strongest tracked post pulled 417 interactions, about 12x its own typical post. Recurring topics include #csic, #gade, #eclipse.

Compared with accounts its own size
CSIC's engagement rate beats 23% of the tracked X accounts closest to it in follower count (3,739 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 35% 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%, CSIC sits above the 10th percentile of the 36,261 accounts in this comparison. That places it in the bottom 25% band, which runs below 0.012%.

Posting timing
This account posts most often around 09:00 UTC, and Thursday 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.

#ACTUALIZACIÓN 🔴Registrados varios seísmos en el área metropolitana de #Granada 📣Si has sentido el terremoto, te encuentras bien y tu vivienda no presenta daños, mantén la calma y evita entrar y salir de los edificios innecesariamente. No utilices el ascensor. 🏢En la calle, aléjate de fachadas, cornisas, balcones, muros y otros elementos que puedan desprenderse. #AndalucíaPreviene

Ranked by total interactions across everything we have tracked for this account, which is a longer history than the 30-day window the rates above use. The multiple compares each post to this account's own median.
Recurring topics
The most frequent hashtags in the sampled posts. They describe what this account writes about; they are not a performance signal, and the catalog-wide breakdown on the hub shows how little hashtag count moves.

- What is CSIC's engagement rate on X?
- CSIC (@CSIC) has an engagement rate of 0.004%, based on the median interactions across 56 original posts from the last 30 days against 925,537 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.004%, CSIC sits above the 10th percentile of the 36,261 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 @CSIC have real engagement?
- Its engagement rate beats 23% of the tracked X accounts closest to it in follower count (3,739 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 @CSIC post?
- Most posts go out around 09:00 UTC, and Thursday is its busiest day, at roughly 2.77 posts per day across the measured window.
