The Google AdSense program represents advertisers ranging from large global brands to small and local companies. With Google's extensive advertiser base, there are ads for all categories of businesses and services and for practically all types of content, no matter how broad or specialized.
Since Google provides the ads, you have no advertiser relationships to maintain.
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.
You can log in into your AdSense account at any time and find out how much you have earned. Once in a month, Google will send you a cheque for the money you have earned.
You will learn more about the AdSense program, when you sign up for it.
