What is a Facebook Like Box?
Essentially, it is a way to encourage Facebook users to like your page by showing them on your website who is already connected with you, and what kind of things you post. According to Facebook:
“The Like Box is a social plugin that enables Facebook Page owners to attract and gain Likes from their own website. The Like Box enables users to:
– See how many users already like this Page, and which of their friends like it
– Read recent posts from the Page
– Like the Page with one click, without needing to visit the Page”
