Successful marketers have known for a long time that the more often you can get your product in front of potential customers, the more likely they are to buy. For traditional marketers, this has usually been accomplished by methods such as print, radio, or TV advertising.

Basically, in your Google AdWords account, you can specify that you want to display ads for your products or site to people who have already visited your site from a paid click.
