The best Adwords information I have found is from
Perry Marshall. He has a free 5 day mini course that serves as a great place to start.
Also, consider that Google has 51% marketshare in the search market. This means the others (like Yahoo, MSN, AOL) are typically less expensive but will still reach millions of people. You may want to try those, too.
I also like to test run my Ad campaigns on
AdBrite's network, which is generally cheaper as well. And then when you find good ads that work well, then take them over to the bigger networks.
When you spend money on Google or any of these, you have to make sure you are getting something from it. The more they click, the better the ads -- but you have to make sure you are getting sales, names and emails, feedback etc., to justify the investment.
