i'm assuming that you already have a website with AdSense and now how to optimize the income from AdSense.
Step one is By Tweaking the ads ( to make them more apealling to your visitors )
Step Two is By Optimizing your website (for better AdSense targetting (or what the google folks call " content relevance " )
and the only way to get number one and two right is by :
Ster three , Tracking Visitors Response. If you dont know what works and what doesnt in trying to increase your adsense revenue...you're shooting arrows in the dark,it wont hit.
the right tracking tool can can reveal a great deal of your visitors and answer fundamental question such as "what're they looking for" and "what makes them..'click' " once you've figured that out,BINGO..you're on your way to big AdSense bucks!
