Google AdSense and Adwords
Adwords : Google's advertising network, where advertisers can pay a certain amount for each click. You can setup how much you want to spend per day on advertising, and create several custom text ads, which will rotate through the search engine results and/or content pages as well.
Google AdSense 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 your visitors’ search request.
