I just started my first arbitrage website and would like to ask few questions 
I have a 6 page website with nice layout with 1 link unit at top "that looks like navigation", 1 image + 336 block + menu links at top under link unit, all this as header, one 336 block in content and also a 160x600 skyscraper in the right... and had between 2-12% CTR... I must mention I just started this 3 weeks ago... getting traffic from 7 search...
My ads were relevant for first 2 weeks... now they show all kinds of ads except related to what content is focused on (top keyword density)... though the link unit at top is showing ads correctly... all 5 links perfectly related... very strange... I was getting $1-$1.5/click and now I get most $0.05-$0.20/click... only link unit at top that has relevant ads brings me $0.50-$1 clicks like before... does anyone know what's happening? could be this because I did not update my website in the last 1-2 weeks?
