If you have a blog or website, you can promote it on Facebook using the Like Box. Previously Facebook used to have the “Become a Fan” box and now they have replaced it with the Like Box. You can also add the like box to your blog or website. To add the like box, open the Facebook Social Plugins page. Here you will be able to see the options to customize the Like box for your blog.
You just need to specify the page ID which can be got from the Facebook page and then add the width and height and click the Get Code button. Copy and paste the code in your blog where you want it to be shown.
Next time you post an article on your blog, it will be visible to all the people who have liked your blog.
