What is Google Adsense?

Google Adsense is an Advertisement service that is controlled and managed by Google. The ads are created and paid for by advertisers who want to advertise/promote their products, since these advertisers pay different prices for different ads the amount you earn will vary. Basically this program is designed for both publisher and advertiser, advertiser needs traffic on their products site and on the other hand publisher need to display their tagated video, image or text advertisements ads on their websites and earn money when site visitors view or click these ads. Website publishers simply need to create an AdSense free account and copy the ad code from Adsense account to their website and display the ads. Revenue is generated on per-click or per-impression basis.
