Everyone could use some supplementary cash. Maybe you want to buy a new computer, a music player, or something else. However you simply can’t afford to spend money for those. Maybe you don’t earn enough money with your current job, or you don’t have a job at all. If you’re like me, you waste a lot of time on the computer and online. How about using some of that spare time to earn some extra money?

Here are 5 ways you can make money with your computer:

1) Join an affiliate program and promote your affiliate link. You earn commissions when someone buys through your link. This is a very popular way of making money online. Many affiliate programs are free to join. Some ways you can promote your affiliate link are through pay per click advertising, setting up a website or e-mail marketing.

2) Start a blog about a particular subject. Pick a subject that your visitors would find interesting, and give them useful information on a regular basis. Keep your blog focused on your topic, and update with new information and articles on a regular schedule. On your blog, you can promote and review affiliate products and/or make money with a program like Google Adsense. You can start a free blog with a service such as Blogspot.

3) You can make money solely on Google Adsense, or another related program. Set up a site providing useful information about a certain subject, then drive traffic to your site. Place Adsense ads on each page of your site. Make sure your site follows the terms of service of your pay per click ad program. When people click on those ads you make money, so a lot of traffic is key.

4) Another way you can make money with your computer is through internet auctions, such as eBay. Millions of people search eBay every day looking for every product you can imagine, and there are millions of items being sold through eBay daily. There are people who make fortunes just from selling on eBay. A way to make money is to buy items at wholesale price and sell them for profit on eBay. However there is a lot more to learn in order to make money from internet auctions.

5) Creating your own informational product and selling it online is yet another way to make money with your computer. Information has got to be the most common kind of product to create and sell on the internet. Write an ebook on a topic that people would be willing to pay for and sell it, keeping all the profits for yourself. Perhaps you know information on something that a lot of people do not, and people are willing to pay for that kind of information. A similar method is to obtain the master resell rights for a product, and sell the product for yourself.

These are only a few ways to make money with your computer. There are many more ways that you can explore and research. Find something that suits you best, and something you are willing to commit to.
