A typical post picks up 119 interactions against 78K followers, an engagement rate of 0.153%. Measured over 18 original posts, its engagement rate beats 57% of 6,874 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 9.0K times each, and 1.32% of those impressions turn into an interaction. That is about 11.6% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.6 post a day over the last 30 days, with activity on roughly 53% of days. Most posts go out around 13:00 UTC, and Monday is the busiest day of the week. Of the 18 posts sampled, 94% carry an image or video and 6% link out. The account's strongest tracked post pulled 2.1K interactions, about 18x its own typical post.

Compared with accounts its own size

Jakub Železný🇨🇿's engagement rate beats 57% of the tracked X accounts closest to it in follower count (6,874 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 49% 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 0.153%, Jakub Železný🇨🇿 sits above the 50th percentile of the 66,393 accounts in this comparison. That places it in the above the median band, which runs 0.1% to 0.499%.

Engagement rate as a share of followers, across the 66,393 accounts we have scanned enough to measure. The axis is logarithmic, because the top and bottom of this population are about 56,924 times apart and a linear axis would flatten everything below the median into a single point.

Posting timing

This account posts most often around 13:00 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.

Engagement by hour posted, UTCTwenty-four bars, one per UTC hour. Each bar shows how posts published in that hour compare with their own authors' median engagement. Bars above the centre line ran higher than the median, bars below ran lower. A marker flags Busiest hour: 13:00 UTC.

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.

This account's posting mix compared with catalog-wide effects
FormatThis accountCatalog effect95% intervalAccounts behind it
Image or video94% of posts+111%+108% to +115%34K
Outbound link6% of posts-41%-42% to -40%32K
Typical length-+15%+14% to +16%32K
  • 94% 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.
  • 6% of its posts carry a link off X. Across the catalog, posts with an outbound link run 41% below the same accounts' other posts.
  • Its average post runs 301 characters, which falls in the over 280 characters band. Across the catalog, posts over 280 characters run 15% above the same accounts' other posts.

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.

    Pořád vídám tyto billboardy; doteď jsem myslel, že za bezpečné Česko ručí policie, zpravodajské služby, ozbrojené síly…ale ok. Co tedy pán z billboardu, když byl návštěvou v komunistické totalitní Číně, udělal pro bezpečí občana Česka, zatčeného v komunistické totalitní Číně? J. https://t.co/KBSJ3EzdDI

    Proč @petr_macinka nepustí novinářku na TK? Bojí se otázek? Neumí odpovídat? Nevpuštění (opět!) @zdislavapokorna na @mzvcr je ubožárna a bolševická manýra. A škoda (vím, chtěl bych moc), že ostatní kolegové do jednoho neodešli a nenechali žvanit účastníky TK k prázdnému sálu. J. https://t.co/Ou9h2RsDdm

    Dnes: nezvykle masivní nasazení sil+prostředků @PolicieCZ nejen v okolí, ale výjimečně (i psi) uvnitř(!) ruské ambasády. Je-li takový zásah uvnitř, musí jít o výslovnou žádost té diplomatické mise, z vážných důvodů. Že by nějaká hrozba? Nu…vystěhujte se a budete mít klid, ne? J. https://t.co/CyEUQPSTYM

    I koalice v PSP, i @tomio_cz Okamura, snad musí vědět, že Ukrajina se brání vražedné agresi ruského režimu, vedeného bolševickým kágébákem. Agresi, která je zcela proti i našim ústavním hodnotám. Zamítnout cestu místopředsedkyně @snemovna @BaraUrbanova na Ukrajinu je hanba.🇨🇿🇺🇦J. https://t.co/2ntBsBwOdV

    Léta podporuji menšiny. I tu dnes v Praze pochodující. Pár stupidů si i myslelo, že k ní patřím. Nepatřím, je to princip. Ale: jakou logikou část pochodujících podpořila teroristy? Dobře píší @novinkycz, kde právě kvírstvo není vítáno. Ono by to kvírstvu vysvětlilo…Hamásstvo. J. https://t.co/sNvXgZJHst

    Ve vší úctě si nejsem jist, že je @tomio_cz se SŠ vzděláním expertem na vzdělávání. A 9. třída u nás nebyla “zavedena”, ale “obnovena” v 90. letech! A smysl má. Já měl poslední vysvědčení na tehdá osmileté ZŠ den před 14. narozeninami, maturoval jsem v 17. Oboje zbytečně brzo. J. https://t.co/FV84Bq444S

Reading these numbers

A typical post picks up 119 interactions against 78K followers, an engagement rate of 0.153%. Measured over 18 original posts, its engagement rate beats 57% of 6,874 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 9.0K times each, and 1.32% of those impressions turn into an interaction. That is about 11.6% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.6 post a day over the last 30 days, with activity on roughly 53% of days. Most posts go out around 13:00 UTC, and Monday is the busiest day of the week. Of the 18 posts sampled, 94% carry an image or video and 6% link out. The account's strongest tracked post pulled 2.1K interactions, about 18x its own typical post.

What is Jakub Železný🇨🇿's engagement rate on X?
Jakub Železný🇨🇿 (@JakubZelezny) has an engagement rate of 0.153%, based on the median interactions across 18 original posts from the last 30 days against 77,858 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
Is that a good engagement rate?
At 0.153%, Jakub Železný🇨🇿 sits above the 50th percentile of the 66,393 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 @JakubZelezny have real engagement?
Its engagement rate beats 57% of the tracked X accounts closest to it in follower count (6,874 accounts), which puts it in the middle of its size range 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 @JakubZelezny post?
Most posts go out around 13:00 UTC, and Monday is its busiest day, at roughly 0.6 posts per day across the measured window.
