Google AdSense

Google AdSense is an automatic, programmatic way for website owners to earn money by displaying ads on their websites. Advertisers can bid on keywords to have their ads displayed on websites that are related to those keywords. Publishers (website owners) then pick which ads to show on their site, and receive a portion of the ad revenue generated by those ads.The Google AdSense API gives developers a way to programmatically access the functionality of AdSense. This includes the ability to get information about ad units and earnings, create and manage ad units, and get reports about how ads are performing on a website.The AdSense API is a RESTful API that uses HTTP verbs to manipulate resources. Requests and responses are formatted in JSON.
