Google adwords is a text-based system for advertising on its site and its partner sites. The service allows you to create your own ads, choose keywords to help match your ads to your audience, and control the cost of your advertising—you pay only when people click on your ad (a cost per click plan). Anyone wishing to promote a product on Google can enroll in this program.
