1. Apply for the AdSense Program. Visit www.google.com/adsense to fill out the online application form. Answer the questions completely and accurately. You will need either a blog or a website where you can put ads on.
2. Wait for the response e-mail. Probably the most anxious you'll be during this process no doubt.
3. You'll receive a response letting you know if the application was approved or denied. If you have tried AdSense previously and canceled your account, you CAN reapply for a new one, you'll just have to use a different e-mail address in the application. If you have tried it and were canceled by Google, you are not eligible to participate in the program anymore.
4. Once your application is approved and you receive an e-mail confirmation, click the link inside the e-mail to go to your account. There you can create ads to put into your website. The instructions are easy to follow and simple to do.
5. Try experimenting with different ad styles. The more creative you are, the more the monetary possibilities exist. The nice thing about the program is you can track which ads are your main sources of revenue.
6. Another way to earn money through AdSense is by using a third party, such as this site, eHow. I've mentioned this before in my internet business article. With using a third party site, they have applied to the AdSense program and give you a cut of ad revenue generated from your pages.
