Google AdSense provides a way for publishers to earn money from their online content. AdSense works by matching ads to your site based on your content and visitors. The ads are created and paid for by advertisers who want to promote their products. Since these advertisers pay different prices for different ads, the amount you earn will vary.

AdSense in three steps

1. You make your ad spaces available	2. The highest paying ads appear on your site	3. You get paid
You make your ad spaces available by pasting ad code on your site, and choose where you want the ads to appear.	Advertisers bid to show in your ad spaces in a real-time auction. The highest paying ads show on your site.	We handle the process of billing all advertisers and networks for the ads on your site, to make sure you receive your payments.

Ad format

The way an ad is shown to the users on your site. For example, an ad may be displayed within the content of your page (e.g, text and display ads), displayed over the top of your page (e.g., anchor ads), etc.

Different ad formats can support different ad types, such as text, display, video, etc. Ad formats may also vary in the number of individual ads they display. For example, the banner ad format will display up to two ads horizontally across the page and the skyscraper will display up to four ads vertically.
