Bitly helps you share, track, and analyze your links

You can shorten long URLs to paste into other documents, especially a direct link to a specific search, for example, if you want to show it to students.
This way: www.to-teach-to-learn.blogspot.com becomes http://bit.ly/syuw2w

Afterwards, you can analyze how many people have clicked your bitly links!
