Engagement
A typical post picks up 103 interactions against 1.2M followers, an engagement rate of 0.009%. Measured over 18 original posts, its engagement rate beats 32% of 21,185 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 28K times each, and 0.371% of those impressions turn into an interaction. That is about 2.37% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.83 post a day over the last 30 days, with activity on roughly 47% of days. Most posts go out around 07:00 UTC, and Sunday is the busiest day of the week. Of the 18 posts sampled, 28% carry an image or video, 6% are part of a thread and 67% link out. The account's strongest tracked post pulled 11K interactions, about 107x its own typical post.

Compared with accounts its own size
M. Serdar Kuzuloğlu's engagement rate beats 32% of the tracked X accounts closest to it in follower count (21,185 accounts, accounts of similar size (decile 10 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 25% 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.

At 0.009%, M. Serdar Kuzuloğlu sits above the 10th percentile of the 212,078 accounts in this comparison. That places it in the bottom 25% band, which runs below 0.025%.

Posting timing
This account posts most often around 07:00 UTC, and Sunday 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.

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.
| Format | This account | Catalog effect | 95% interval | Accounts behind it |
|---|---|---|---|---|
| Image or video | 28% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 67% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | no effect | -2% to -1% | 42K |
- 28% 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.
- 67% of its posts carry a link off X. Across the catalog, posts with an outbound link run 41% below the same accounts' other posts, so a large share of this account's output sits in the weakest bucket we measure.
- Its average post runs 192 characters, which falls in the 180 - 280 characters band. Across the catalog, posts of 180 to 280 characters match the same accounts' other posts almost exactly.
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.

"Silo" adlı #dizi'ye tesadüfen başladım. Bir anda içine çekti. Uyarlandığı #kitap'ı merak ettim. @ithakiyayinlari Türkçeye kazandırmış. Bugün o da bitti. Kitabını okuduğum film ve diziler genellikle yavan gelir. İlk istisnası Silo oldu. Dizinin yaratıcı ekibi hem kitabın özünü ekrana kusursuzca aktarmış hem de müthiş bir alternatif öykü akışı yaratmış. Yeni hedefim, hepsine ilham kaynağı olan: Philip K. Dick imzalı "The Penultimate Truth" (Sondan Bir Önceki Gerçek / @alfakitap).

Telefonda tartışanlara mutlaka kulak misafiri oluyor ve bundan büyük keyif alıyorum. Duyamadığım tarafın sözlerini hayal ederek zihnimde tamamlıyorum. Genelde incir çekirdeğini doldurmayacak meseleler oluyor. Hepsinin kökeninde yetersiz sevişme var.

TRT, Faik Baysal'ın "Kavanozdaki Adam" adlı tiyatro oyununu 1987'de 4 bölümlük bir diziye uyarlamıştı. Türkiye'nin ilk bilimkurgu TV dizisi sayılır. Black Mirror benzeri bir etki yaratmıştı. Baktım, YouTube'a da yüklenmiş. Meraklısına #tavsiye olunur. https://t.co/r9UQWD2OcY

Bir kitabın peşindeyim. Baskısı bitmiş. Sahaf 17 liraya satıyor. Gönderim maliyeti 130 lira. Metroya binip alıp gelsem, yol parası 92 lira. Neyse ki 2 bin liralık kitap alırsam gönderim bedava olacak.
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 M. Serdar Kuzuloğlu's engagement rate on X?
- M. Serdar Kuzuloğlu (@mserdark) has an engagement rate of 0.009%, based on the median interactions across 18 original posts from the last 30 days against 1,170,662 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.009%, M. Serdar Kuzuloğlu sits above the 10th percentile of the 212,078 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 @mserdark have real engagement?
- Its engagement rate beats 32% of the tracked X accounts closest to it in follower count (21,185 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 @mserdark post?
- Most posts go out around 07:00 UTC, and Sunday is its busiest day, at roughly 0.83 posts per day across the measured window.
