What is Google AdSense?
Even if you do not know what is Google AdSense, you would have seen it in many web sites. This is an advertising program offered by Google.
If you look at the top or left bar of this page, most probably you will see the Ads from Google. It is the little blocks of Text Ads with a small message saying 'Ads by Google' in the bottom or on the top of the Ads.
Sometimes, Google shows images Ads, but most of the time they are text ads with a title, small description and a link to the advertiser. When any user click on the Ad, the publisher (web master) gets paid from Google. In fact, the advertiser pays Google for each click and Google pays a portion of the amount to the website who publish the Ad.

How Google AdWords and AdSense work?
The way it works is, the advertiser must select the keywords they are targetting. For example, if the advertiser is selling digital cameras, they may want to choose the keyword 'digital camera' and bid some amount for those words. They can decide what amount they want to bid.
Any webpage which publish Google AdSense has to insert some scripts given by Google. This script will send information about the page to Google. Google will evaluate the content of the page and return some Ads related to the content and based on the bids advertisers make for the related keywords. Highest paid ads will be given higher priority. Ads with low bids may or may not get displayed depending on the keywords and the amount they bid.
How much a publisher will get paid per click?
Usually, most of the advertising agencies pay around 50% of the amount they get from the advertiser. But Google never discloses the percentage they give to the publisher. The only information the publisher can get is, how many clicks they got, what is the total amount they earned etc. Publisher can view several reports from their AdSense accounts. Google will send money to the publisher every month by check, bank transfer etc.
