There are at least two ways in which sites can make money:
1. Advertising Revenue
2. Selling Goods and Services
ClixGalore

This company is used by many vendors to sell their software products. It allows affiliates to put links to these products on their website and earn commission for purchases made through those links.
LinkShare Corporation
This is a network of affiliate programs that handles accounts from a large number of advertisers. The rates of payments vary from advertiser to advertiser, with most paying commission for sales made.
Amazon.com Associate Program
Fancy selling books on your website? If so, the well-known Amazon.com provides an affiliate program that pays you referral fees on books sold. The usually heard complaint about this program is that visitors would usually just note the book on the Amazon site, or bookmark the Amazon site itself, and return at some later time to buy the book. When that happens, the purchase is not registered as having come through your site, so you lose the referral fees on that sale. There's no referral program. Note that it is apparently not easy to earn much from this scheme, and many sites report disappointing performance (as compared to other affiliate programs).
Google AdSense
This program displays advertisements on your site relevant to the content of the page you placed the supplied code on. You are paid according to the number of clicks the ads (PPC - pay per click) on your page receive. It also provides you the ability to filter out competitors' ads.
