If I 'like' a post that is a shared a web page within Facebook, is that in any way connected to the number of likes that are shown on the actual web page in the Facebook share button?
Put otherwise: To acquire likes on an external web page, does one actually need to click the like button on that external page?
Put slightly otherwise: Is there any way within Facebook to add to the number of likes shown on an external web page's facebook like button?
