Large and small website owners, bloggers and more use Google AdSense to make money by placing targeted advertisements on their sites. Whenever visitors click on an ad, the site owner earns a little revenue. These small earnings can add up to decent amounts, depending on how many visitors the site draws and how many ads owners choose to place. It is free to sign up for AdSense, to use it and to get paid; no credit card is required at any time.
Instructions:
1) Register with AdSense by going online to google.com/adsense and clicking on the "Sign up now" link. You will have to provide contact information, including a street address, but not a credit card number.
2) Read the instructions on adding AdSense to your website and implement the options that best suit you.
3) After earning the minimum amount for payment, AdSense asks you to choose a payment method. As of summer 2010, the options for payment include a check in the mail, electronic funds transfer, Western Union Quick Cash and the Rapida cash transfer service. No credit card is required.
4) Google AdSense calculates payments monthly and sends money to users who have reached the threshold. The time to receive earnings varies depending on the method of payment chosen.
