Google Adsense

What is Google AdSense?
It is the program that can give you advertising revenue from each page on your website—with a minimal investment in time and no additional resources.
AdSense delivers relevant text and image ads that are precisely targeted to your site and your site content. And when you add a Google search box to your site, AdSense delivers relevant text ads that are targeted to the Google search results pages generated by you. You can maximize your revenue potential by displaying Google ads on your website. Google puts relevant CPC (cost-per-click) and CPM (cost per thousand impressions) ads through the same auction, and lets them compete against one another. The auction takes place instantaneously, and, when it’s over, AdSense automatically displays the text or image ad(s) that will generate the maximum revenue for a page -- and the maximum revenue for you.
Becoming an AdSense publisher is simple. All it takes is a single online application. Once you're approved, AdSense takes only minutes to set-up. Just copy and paste a block of HTML and targeted ads start showing up on your website.
With Google's extensive advertiser base, we have ads for all categories of businesses-and for practically all types of content, no matter how broad or specialized.
And since Google provides the ads, you have no advertiser relationships to maintain.
The AdSense program represents advertisers ranging from large global brands to small and local companies. Ads are also targeted by geography, so global businesses can display local advertising with no additional effort. And you can use AdSense in many languages
