The Internet is used primarily for the exchange of information. While that might not sound very useful for you, that's the key concept behind many of the ways to make money online for free. The Internet is an unparalleled medium when it comes to exchanging information. Nowadays, many companies are willing to exchange your ideas and information - with their money.

1. Fill out Surveys

Filling out surveys is a fairly new activity but the trend has spread like wildfire in the past few years. It is acknowledged as one of the easiest ways to make money online for free; after all, how much do you stand to lose by just sitting at your computer and dishing out your opinions? Survey companies show their appreciation in a wide variety of ways, from giving you restaurant coupons to paying you with cold, hard cash.

2. Get an Online Job

Working online might sound like your regular old day job but it has numerous benefits that your 9-to-5 work cannot give you. Because you don't have to commute to work, launder your professional attire or buy lunch at the office, you cut down on much of the cost of regular working. If you are industrious you could earn hundreds, even thousands of dollars in a month - all without a single cent of capital or cost.

3. Launch your Own Business

When done right, running your own business can become a great way to make some cash online without high costs. There are many drop shipping and affiliate companies out there that will give you this tempting offer: give them customers and they'll give you a share of the profits in return. You are basically going to just link the customers to the sellers - nothing a couple of emails won't solve - and then get paid in the process.

Don't think of these as get-rich-quick methods on the Internet. You may make money online for free with these methods, but unless you are willing to commit to working at it religiously, you cannot expect to get high returns.
