Facebook have been making a number of additions to their ‘public profiles’ recently (what used to be called fan pages); the latest of which is to add viral invites to pages, as All Facebook report. This means that a fan of a public profile can send direct invites to their friends, similar to applications. The effect of this won’t be dramatic, as if people really wanted to share a page with their friends they could do it with the share feature, however this could be a stronger call to action for users; and it’s certainly something which brand owners of pages have been calling for.
