Google Analytics makes it simple to measure the clicks to links within your own site. But Google Analytics also provides a way for you to track clicks on links that lead to to other websites, away from your website.
It is useful to see where people go when they leave your site; indeed there are websites making a good living by charging companies to send clicks their way. This is a free way to count those outbound clicks.

The outbound clicks will appear in my Top Content report.
