One of the biggest problems bidding on keywords in Google AdWords PPC (and all other Pay Per Click engines) is that you don't know if they are really going to be effective, until after you've blown wads of cash testing them for real. But that's all about to change. 37 AdWords Secrets have now released a new, free tool that does all the work for you. After you plug your keywords into this new desktop-based keyword tool (very easy to use) simply avoid bidding on keywords that have a rank of less than 0.50.
