Let’s face it, urls can be long and with Twitter’s 140 character limit, link shorteners can be very useful. There are several free services but I tend to use Google url shortener. It’s free, easy to use and tracks stats like the number of clicks.
To make the process of generating a short url easier, I created a chrome extension that uses Google link shortener api to quickly generate a short link and copies it to your clipboard. If you shorten links often, you should check out my chrome extension.
