I started using this place and ended up getting more hits and traffic than I was getting on my Google Adwords promotion. Most keywords are $.05 - yep a nickel, compared to Google and Yahoo at a few dollars in some cases. There's also a free $5.00 credit for signing up if your web host is an affiliate member. Otherwise you can go to www.kanoodle.com to sign up. Let me know how it works out for you.
