When one of your customers makes a purchase, you purchase the product from a third-party company (the drop shipper, usually a manufacturer or wholesaler) for a lower price. This process is as simple as forwarding the order from your customer, a process that can actually be completely automated. (Remember you don't have any risk here of buying inventory because the sale has already been made).
Once a site or blog is created and optimized for SEO (search engine optimization) purposes, the search engine marketing (SEM) begins. The potential for earning income in this area is literally through the roof if you know what you’re doing. An expert in SEO management is responsible for successfully marketing a website and can choose to promote it in a variety of ways.
You know this one already. You include links to products you are promoting as an affiliate and every time somebody buys the product, you get a commission. With a blog, you can integrate advertising with content to make it even more likely you’ll get the sale. For example, you could do a product review—which is useful content—and then include a link to buy the product under an affiliate link.
Best of all, unlike a brick-and-mortar business, you don’t need a lot of startup capital. In fact, you can get many internet businesses up and running with no money at all because so many free services facilitate the possibility. For example, you can set up a website or blog for free using WordPress. Or you can leverage a third-party site like Amazon or eBay to sell goods with no inventory costs. You use their selling platform in exchange for giving them a cut of your sales.
