1.Affiliate Marketing

Affiliate marketing is somewhat similar to drop shipping but with some key differences. With this e-commerce model, you again don’t maintain an inventory of your own products, and you don’t have to worry about shipping products to customers.
Basically, you pick a profitable niche for your online business, and then you find an affiliate partner who has products available in that niche. Some of the most popular affiliate sites are Clickbank.com, Amazon.com, and CJ Affiliate by Conversant (formerly Commission Junction). Between them, they offer just about any digital information product (like ebooks, audio files, video files) or physical products you can think of. Many big-name companies and brands like Wal-Mart and Home Depot run their own affiliate programs.
With affiliate marketing, you offer the products for sale, for example, on your blog or e-commerce website. Each product has a unique link that tracks back to your account with your affiliate partner. A prospect who clicks on the link is taken to your partner’s shopping cart for checkout. Once they buy, that purchase is recorded and you receive a commission. Commission amounts vary depending on the affiliate partner but are generally 5 percent to 25 percent, or 50 percent or more with digital information products. As you can see, there’s little risk on your part, and virtually no investment needed either. Just like with drop shipping your only costs will be marketing and advertising to drive traffic and generate the sale.
