What is Google AdWords?

Google AdWords is a quick and simple way to advertise on Google, regardless of your budget. AdWords ads are displayed along with search results on Google, as well as on search and content sites in the growing Google Network, including AOL, EarthLink, HowStuffWorks, & Blogger. With searches on Google and page views on the Google Network each day, your Google AdWords ads reach a vast audience.
When you create an AdWords keyword-targeted ad, you choose keywords for which your ad will appear and specify the maximum amount you're willing to pay for each click. You only pay when someone clicks on your ad. To save you even more money, our AdWords Discounter automatically reduces the actual CPC you pay to the lowest cost needed to maintain your ad's position
