 ====== Cell Stats ======
-This is a feature aimed to take into account the position of a thumb on a page. Ie thumbs at the top of a page usually get more clicks then bottom ones. Thus to equalize their chances to get to the top we can apply Cell K to thumbs' CTR.
+Cell Stats accounts for position-based clickability. Thumbnails at the top of a page are more clickable than those in the middle—users see top content instantly but have to scroll to see middle content.
-Here's an example:
+Since identical thumbnails in different positions get different CTRs, you can adjust for this using a clickability coefficient (K) for each position. The most clickable cell (top row) gets K = 2; the least clickable (near the bottom) gets K = 1. This means 2 clicks in the top position are normalized to 1 click in the bottom position.
+**Example:**
+  * Thumbnail A (top position) — 5% CTR
+  * Thumbnail B (bottom position) — 3% CTR
-Let's say we have a thumb A at the top gets  5 clicks and another one (B) at the bottom 2 clicks  (let's add we had 10 views). CTR of the thumb A will be 5/10 = 0.5 , B - 2/10 = 0.2
+After normalization:
+  * Thumbnail A — 2.5% CTR (5% ÷ 2)
+  * Thumbnail B — 3% CTR (3% ÷ 1)
-But if we know the the one at the top is 5 times more likely to get a hit - we can apply this K and it's CTR will be  0.5 / 5 = 0.1 and this is a way for the thumb И to get to the top.
+The script calculates each cell's K automatically over time. For reliable results, collect data from 20,000-30,000 clicks.
-If you have enough traffic you can use "Recalculate Cell K, Recalculate Cell K each minute " and script will try to figure out Cell K automatically. Or you can set it manually in Rotation - Cell K.
+**For New Sites:**
+If you don't yet have enough traffic (< 10k clicks), manually set cell K values and disable "Use Cell K" until you reach ~20k clicks.
+**Quick Setup:**
+Go to **Rotation → Cell Stats → Manual Set cell K** and set:
+  * Start = 2
+  * End = 0.5
+This evenly distributes K values from top to bottom across the page.
