There are 2 types of FB Likes that can be added to your website. One will allow visitors to Like your FB page and the other to Like your website. The code that needs to be embedded on your website can be found here:
- Like Box (allows visitors to Like your Facebook page)
- Like Button (allows visitor to post that they Like your website on their Facebook Wall)
Each of these has a set of parameters that can be configured including whether to display the faces of the people who Like your business. According to our friends at tcb marketing, showing faces attracts more Likes.
