Edited by Zecanard, Flickety, Eric, Jordan and 21 others

Facebook has recently added the ability for its users to "Like" just about any content on the web and have that activity posted to the users' walls. This facility lets you share content more readily and also gives you an idea of how some of your readership traffic is responding to your content.

This article provides step-by-step instructions on how to add the "Like" button to your Blogger (BlogSpot) blog, one of the more commonly used blogging services.

Steps

1. 
   1
   Go to the "Facebook Developers" page: http://developers.facebook.com/docs/reference/plugins/like.
2. 
   2
   Set the options you want. Specifically, select whether you want a "Like" or a "Recommend" button. The sample button on the page will automatically update to reflect your selections.
3. 
   3
   Leave the "URL to Like" field blank. You will be replacing that soon.
4. 
   4
   Click "Get Code". You will see something that looks like this:
   
   
   

   <iframe src="http://www.facebook.com/plugins/like.php?href=
   

   
   

   http%253A%252F%252Fexample.com%252Fpage%252Fto%252Flike&layout=standard&
   

   
   

   show_faces=false&width=450&action=like&colorscheme=light"
   

   
   

   scrolling="no" frameborder="0" allowTransparency="true" style="border:none;
   

   
   

   overflow:hidden; width:450px; height:px"></iframe>
   

5.

   Replace the following text:
   • src= above with:

     expr:src='
     

   • http%253A%252F%252Fexample.com%252Fpage%252Fto%252Flike&layout part with:

     " + data:post.url + "&layout
     

   • light" with:

     light"'
     

     -- notice the new trailing apostrophe
   • height:px with:

     height:35px
     

     -- otherwise, Firefox will make the iframe really big.
   • Leave a copy of the final code somewhere accessible for you to transfer to Blogger.
6. 
   6
   Go to your Blogger Dashboard.
7. 
   7
   Open your blog's layout and click Edit HTML.
8. 
   8
   Find a place to put the Facebook "Like" code into your HTML layout. A good location is directly after or below:

   <div class='post-footer'>
   

   • Use the browser "Find" mechanism to help you locate it.
9.

   Save and check that the button has appeared. Once you can see it, you're done!
