Google AdSense:
AdSense (www.google.com/adsense) is popular with bloggers and other people who run noncommercial sites. You sign up, paste a few lines of code from Google into the HTML for your site, and let Google fill in your pages with color-coordinated ads. When somebody clicks one of the ads, Google pays you part of the fee they charge to advertisers (the amount varies, and the company doesn't disclose its payments).
Even though you can't decide which ads appear on your site, Google AdSense does a very nice job of assessing your pages and supplying ads that might interest your visitors. For example, if you run a site about the history of yoga, Google is likely to dish up ads for yoga clothing and other yoga related items. That kind of relevance is important, because Google doesn't pay you when somebody just sees an ad on your site. Google pays you when somebody clicks an ad, so you want Google to fill your space with blurbs likely to interest your readers.
The big question is, how much can you make? The exact answer to this is: it depends. If your site gets tons of traffic (visitors) , and you focus on a narrow topic, there's a good chance Google will serve up ads that appeal to a lot of people visiting your site. For example, if you run a popular site devoted to gadgets, you might make enough to buy a new gadget every few months. If your site gets sporadic traffic, or more important, if it's not clearly about something specific, it may be hard for Google to supply highly relevant ads, and you might not make that much.

Ebay:
The eBay Affiliate Program pays Internet publishers, Web masters, online partners, and eBay sellers to drive new users and sales to eBay. Affiliates promote eBay with banners, text links, and other innovative tools, such as the Editor's Kit and the Flexible Destination Tool. In return, they receive commissions for driving new, active users as well as winning bids and "Buy It Now" purchases. Top eBay affiliates in the program average above $100,000 in monthly commissions. eBay sellers can earn commissions by sending traffic to their own listings as well as to other seller's complementary listings. Sellers with a Web site can use affiliate tools such as the Editor's Kit to display their listings there and also cross-promote other sellers' items, earning commissions for every purchase, regardless of the listing format or seller. eBay does not allow sellers to include Affiliate links on any eBay pages such as View Item Pages, My eBay, or My World.
