3 months back in September Facebook introduced Subscribe button for profiles which lets users to subscribe to your public updates on Facebook. When you subscribe to a user’s public updates, his/her updated will start showing on your Facebook wall. Now Facebook has introduced subscribe button for websites which give visitors the option to subscribe to contributors in one click.
The Subscribe button for websites works in the same way as the button on Facebook; once clicked the user will begin seeing the public posts of the person they have subscribed to in his or her News Feed. The subscribe action is also shared – allowing others to subscribe directly via the News Feed stories, and further increasing viral distribution.
