Google adsense

Google Adsense is the most popular ads of internet business. Adsense is divided into two parts, one is adsense for contents, the others is adsense for search. The referrals program is also available but may be cancelled on the end of august in this year.

Google adsense is suitable for all kinds of sites, you can put it at any site you owned that not violate Google's regulation. It is highly recommended. With adsense content at your site, I think that your site would gain a better google rank at google search engine. ^^

You can signup the Google adsense here : https://www.google.com/adsense/login/en_US/?hl=en_US

The earning is based on two calculation :
(1) CPC - cost per click is the amount an advertiser pays each time a user clicks on his/her ad. Google AdWords has a CPC pricing system.
(2) eCPM - effective cost per thousand impression is a useful way to compare revenue across different channels and advertising programmes.

You would be paid if the earning is USD 100 or above. The payment is settled by sending USD cheque to your home. Therefore the mailing address is very important, after certain earning(USD10.0) in your account, adsense will sent a confirmation letter to verify your address. If the earning is less than USD100, the balance would be automatically carried on to the next month.
