after recieving an email from adsense that i violate their policies by having bad navigation (mostly because i placed A LOT ofadsense instead of menu items), i decided to redesign the site. So i did. it looks way better now. but the problem is that my SERPS went really down. A few days ago i was having 4000+ unique visotrs. Today its 500 =( The links have not changed, the content stayed the same too. ( What should i do?
