i just saw this here the first 336 rectangle only showing one ad not 4 , i tried to efresh and visit more pages and i got same results, its not about not enough advertisers cause there are A lot , it looks great only one related ad on the big rectangle is there anyway to do this ?
maybe it changed randomly from time to time but in the end of the post there are a box contain 2 ads , this happen sometimes in my website but the next day it changed wallaho 23lam
as i said ya 3amr u can try refreshing it as many as you want even trying more pages its not time to time issue i believe there is something done .someone just referred me to this https://www.google.com/adsense/support/bin/answer.py?answer=17948 i dont know if this is it or not yet .
no its not about that the website is in arabic and there a lot of arabian advertisers believe me there must be something done to be like this .
It is random , may be releated to his content I had a blog which had similar ads , and sometimes it turned to two ads per square only and sometimes four and sometimes it show a single ad per square
