I keep reading how these tool bars build traffic but no of them explain how they do this. If you know let me know. Also what other reasons are there to get one. Can you tell me the name of one that is good with no or little spyware. I have heard some have spyware. I really don't care about this if it does not mess my computer up
If you have a popular website you get your users to install it and then put a button on it that links back to your website. That's it, basically.
