Google Adsense is really making miracle in Affiliate Marketing

Google offers three ways to make money from them:

Google AdSense for Content - A variety of size and shape ads for placing in your content are available. These can be text or image ads or both - you specify what you'll allow. Ad units are full ads. Link units are simply a strip of text links that your visitors might want to click. Google allows you to put up to 3 Ad Units and 1 Link unit on each page of your Web site, provided you follow its policies - both for AdSense and for Webmasters.

Google AdSense for Search - This places a search box on your Web site. When a user enters a term and conducts a search, a search results page opens, that hosts more pay-per-click ads. You can customize the color scheme of the search results page to harmonize with your web site.

Google Referrals - Here you make money by referring visitors to use a Google product, like AdSense, AdWords, the Google Toolbar and other Google software. Just like Google AdSense for Content and AdSense for Search, Google generates the code that you paste into the desired location on your web page. You can choose from a wide variety of buttons and text links of different colors. As an example of how Google Referrals works, if someone goes to your site and clicks the link and signs up for an AdSense account, when that person earns a $100 from Google AdSense and receives a payout from Google, you'll also receive $100 for referring them. This is a great idea to me, because you can be the world's worst Google AdSense advertiser, but if an ad dynamo happens to visit your site and uses your referral link, you can make money anyway!
