You see your Facebook friends using the “Like” button to share things they like. And you might wonder, how can I get them to like my website too?
Well it’s a lot easier than you may think. Facebook provides the code you need for the “Like” button at developers.facebook.com
All you need to do is add note the URL that is to be liked, then add the code that is automatically generated and you’re in business.
Then anytime a Facebook user clicks the “Like” button, your website will appear in the News Feed of that user’s friends, along with a link to your website.
