Google adsense

if any body know whats is google adsense please guide me i realy want to learn about this.

AdSense (Google AdSense) is an advertising placement service. The program is designed for website publishers who want to display targeted text, video or image advertisements on website pages and earn money when site visitors view or click the ads.

Google Adsense is a CPC (cost-per-click) advertising program that allows publishers (anyone wanting to put ads on their websites) to insert a small amount of HTML into their sites and have ads appear that are targeted and relevant to the content of the site.

How does Adsense work? It starts with the advertisers who choose which keywords they would like to advertise on. Let’s suppose I want to advertise my new line of gardening tools that I just created. I would bid on certain keywords like “gardening, gardening tools, tillers, pulling weeds, etc”

The Adsense spiders would then match my ads up with :

1. Those specific keywords that people type into Google and display them to the top and right of the search results
2. Websites (like yours) that display adsense ads.

The adsense folks will send out Robots to crawl your site to see what all your content is about. If they find that you have content that has some of the same keywords that I (as the advertiser bid for) then my ads will show up on your site next to your article about gardening tools.
