Drive Traffic to the Pages

The third step is to increase the number of visitors, or traffic, to your pages. Just showing ads isn't enough: in most cases, you only make money when visitors click on the ads, and the ads will be clicked by only a small percentage of your page visitors. Increase the number of visitors, and you'll increase the number of clicks.
This step sounds simple, but it's not. In fact, driving traffic to your pages is the hardest step of the process. With so many Web pages out there, the chances that someone will stumble upon yours by accident are small. Your best bets for traffic are to generate good word of mouth and to get your pages higher in Google's page rankings
