The place to get started with Like functionality isdevelopers.facebook.com/docs/reference/plugins/like/ where Facebookmaintains an easy to use tool to create the necessary HTML to be pasted intothe Web page.It’s also important to note that a site owner can choose between the verbs“Like” and “Recommend” to use for their button. Regardless of the verb usedfor the button, the actions are the same.There are also multiple variations and style options for the Like button. Theseinclude: standard (with and without faces), button count and box count. Recentreports have shown that sites which use the standard Like button with the‘show faces’ option enabled experience 2-3 times higher click-through ratesthan buttons without faces enabled.
