Add Google AdSense advertisements to your blog or website. Google’s AdSense is a revenue-sharing opportunity for small, medium and large web sites that places ads for goods and services that are relevant to the content of your site, targeted to the people who frequent your pages. In turn, you get paid a small amount when the ad is either displayed on your page, or clicked on.[9]
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).
Do you love woodworking? Even without a huge workshop, you can create some of the more popular crafts and sell them.  And like most things, your success in business isn’t necessarily related to how skilled you are as a woodworker. So if you can figure out which products consumers want and just create those, you could have a good business plan. and farmers’ markets are a great place to start selling.
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.
Don't use jargon. If you are offering technical expertise, include descriptions that appeal to your client base, not your peers. For example, if you are showing that you can code with PHP and AJAX, don't say "in this case, if the input field is empty (str.length==0), the function clears the content of the txtHint placeholder and exits the function." The person who needs you to work on their site will just scratch their head and say "huh?" Say, instead, "Start entering text into this field, and it will auto-complete."
If you have a knack for creating unique images, there’s no need to fuss over your own inventory. If your creations can be easily printed onto a product, then you can make money. Upload your designs on a variety of websites like CafePress. If someone likes them, the company prints them up and ships the product. You could create unique designs for calendars, books, T-shirts, bags, hats, greeting cards, or posters and get a commission for each one sold. Some of these sites include Zazzle, Teespring and Lulu.

The internet is the great equalizer. In business specifically, it has leveled the playing field. Anyone can start a money-making online business—anyone with a computer, that is. But here’s the thing: virtually no technical experience is needed. Today there are plenty of tools you can use to build an online business that makes the technical work a lot easier than it was in the past.
