Google Analytics provides a very easy way to track your exit links. Now in case you have only a small number of exit links on your website or blog you can use the onclick event to manually embed the GA code that tracks the links as exit links.
For example say your website has a link to the site www.shoppers.com and you want to find out how many users actually clicked on this link to exit your site, you can simply add the onclick event to the HTML link anchor.
So instead of the normal
<a href =http://www.shoppers.com> Shoppers.com</a>
You can put the following code :
This will simply track the click on the link Shoppers.com as a page view and you can get a count of the number of times it was clicked. You can find the numbers under Content in GA.
In my case I used this method to track the number of clicks on the LinkedIn link in my profile in my blog. The code looks something like this:
The numbers look like this:
