AdSense, for many that have been taken in by the hype, is a simple way to make money. There are thousands of ads claiming that you can make substantial amounts of money with Google AdSense in a relatively short period of time. There are also many 'suspect' sites making the same questionable claims. But how can you make money with Google AdSense? Can you really make thousands of dollars a month using one of the most popular Pay-Per-Click schemes on the web? Can you start making money with Google AdSense in matter of months? Unfortunately, too many new publishers join the scheme with completely unrealistic expectations of how much money they're going to make. Too often they step into AdSense believing the sales pitch and the hype and think that they'll be making money almost instantaneously.
I agree Peon, adsense is a lot harder than many people make it out to be. Plus it's never guaranteed, Google can close your account anytime if they want.
you need to make a website on a popular subject and a subject that has high paying keywords.. then you need a lot of traffic
I am following a certain formula for myself to increase my adsense earnings by Researching, Rinsing, and Repeating. That includes content, backlinking, and traffic..
