A little birdy, who will remain unnamed, tells me that from Oct 1 2010 all Facebook ads leading users away from the Facebook platform (e.g. – to external websites) will not be able to use “like” functionality on their adverts. Only ads leading to Facebook pages can use the “like” feature moving forward.

Facebook Advert With Like Function

So, does that mean a higher CPC for Facebook PPC marketers? I think so. Facebook uses a quality score type system, like Google’s, so it’s probable that “like” interaction is used in some way to lower your CPC (cost-per-click). Either that or Facebook no longer want to show that other users find adverts useful. But why?
