It is nice to be able to track various statistics for your website using Google Analytics. It really helps you understand what pages web traffic tend to visit, how they get there, etc. Another nicety is to track social media responses (e.g., Facebook like button clicks) to your pages. You technically can track Facebook like button clicks using the the Facebook Insights tool (http://www.facebook.com/insights/), but it really is very limited and I have found it to be buggy. I prefer to use Google Analytics to track these social media responses because you much more easily see what pages received the responses, how many responses, and correlate it with other metrics available in Analytics. You can even track several social interactions other than just Facebook while you’re at it (like Twitter, Google +1 and even AdSense). The major selling point is accessing all of this from a single tool.
In this post I am specifically addressing how to track Facebook social responses. Tracking the Facebook likes and dislikes for your pages in Analytics is very simple. Assuming you already have added the Facebook like/unlike buttons to your site (by generating the code yourself at http://developers.facebook.com/docs/reference/plugins/like/ or by using a plugin like the WordPress “Facebook Likes You!” plugin), then you only need to add the following code to your site to start tracking the like/unlike responses.
NOTE: make sure to add the following code in the HTML somewhere after the like/unlike button code.
