I have been sort of on and off when it comes to tracking links to my various ads. I have a system at my blog, but not when it comes to article marketing, discussion forums and so on. Do you track your links, if you do, which system are you using? - Jens -
Always track your ads. I wrote my own system, very simple, but also made it to track them once they're on my site too. It tell's me what pages they go to.
