AFAIK you can track your clicks via Google Analytics. If it comes to hiding links from search engine spiders I do it this way:
1. Create folder in your domain directory. (ie domain-name.com/redirects/)
2. Disallow access for all spiders to this directory via robots.txt
User-agent: *
Disallow: /redirects
3. Create an php file for each link you want to hide and place them in redirects folder (ie. nastydollars.php). Inside the file place a header location redirect:
?php
header("Location: http://www.nastydollars.com/");
?
4. Now link only to files you have created (
http://domain-name.com/redirects/nastydollars.php).
