Google AdSense is an advertising network run by Google that allows bloggers and website owners an opportunity to earn money by showing text, image, video, and other interactive advertisement on their websites. These ads are targeted by site content and audience.
Google AdSense is hassle free because you don’t have to deal with advertisers or worry about collecting money. Google administers and maintain relationships with the advertisers. They collect the payment, take their management fee, and send the rest of the money to you.
AdSense offers cost-per-click ads (CPC) which means that you earn money every time a user clicks on the ad on your website. The amount received per click varies based on a variety of factors.
