I am fairly new to using PPC things and have seen negative keywords around. My basic understanding of this is that it filters out keywords so your ad doesn't show there? I thought that you pick and choose which ones it'll show on, not the ones it won't. I don't even remember if it was specifically Adwords I saw this on, but can someone explain how negative keywords work and the best way to use them?

They work basically as you have explained. If you don't want a keyword to be used, just add a "-" before it. So if you don't want "Tim" as part of your keywords, enter "-Tim".

I hope this helps
