With all the over the top hype and buzz about Facebook IPO last week(which BTW fizzled out Facebook shares closed about same as its $38 per share offer price) GM recently pulled its ads from Facebook http://www.google.com/hostednews/af...ocId=CNG.52a5ca780a3437716901ba414fee1472.461 On other hand Ford increased its ads. But as experts have said -you go to Google and search when you want to buy something but with Facebook that is not the case which is why FB has very low conversion rates.
