Does anybody know of a good resource for pay per click training? Newsletters? Articles? Anything?

Thanks.

The best sources that I've seen for up to date, authoritative information information on what's going on in Pay Per Click Advertising are:

www.searchenginewatch.com
www.clickz.com

I also have my own site with PPC articles and reviews that you can find in my profile.

Hope this helps...

There are two ways to learn:
1. Read a lot of info

2. Open a ppc campaign with cheap keywords and dive in head first and learn from your mistakes.

I learned most of what I know from #2.

Here is a website that might be able to help you:

I wrote a few articles for them.
