There are numerous opportunities on the Web today offering ways to earn extra money online, so many people ask themselves a question: "Does it really work"?

If you have been trying to to earn extra money on the Internet for even a short while, you have undoubtedly heard quite a few names being thrown about. It seems as if everyone sees themselves as an expert and everyone who is anyone knows everyone else who is someone. It is like a marketing guru clique. And they make you think that if you do not know somebody, you will always be a nobody.

Product launches, audio and video streaming, teleseminars, and joint ventures, etc. are good income generating sources. The gurus who sell these products and services make a lot of money in the bargain. The products and services are genuine too.

Not surprisingly, the marketers are not showing you all of their cards - they don't talk much about other online opportunities that have potential of generating thousands of dollars a month and without having you spending your money on registration fees at all. These folks are smart enough to make real money from the comfort of their homes without ever lifting a finger - you'll never see them attending numerous seminars held across the country. They don't get involved in joint ventures because no one knows what it is and who they are. The people, we're talking about, usually sit in the comfort of their homes and do a lot of link clicking on a daily basis to generate their monthly earnings.

You'd ask: "How is this possible"? The answer is: Google Adsense, Affiliate links, and content.

Let's look at Google Adsense a little bit more in depth. The search engines work in the following way: they crawl and index content to rank it and offer as best search results possible - they love it and they need as much content as you can get.

Create a website with multiple content pages and the search engine scans the contents, picks up each link to display more content, thereby raising your rankings.

Curious? All you need to do now is to place Adsense ads on each page. Readers going through your pages might click on the Adsense links. If they do, you get your commission from Google. This could be a few cents or even several dollars if you are lucky.

Your visitors never have to buy anything. Just clicking the link makes you money. The more traffic you get to your website, the more clicks you get, and the more money you will earn.

Now all you need is content. It is possible to write your own content when you know how to do it right. But most of us are not.

A lot of people write articles and post it on the Internet. Carry out a search and use these in case you are not good at writing your own. The best part is that as long as you include the resource box with each article, you need not even pay for them. This seems the best option to go for.

However, sometimes users will not click on Adsense links, but rather on the referral link to the article's originating website, not earning you a dime.

You can also use Private Label Rights articles. You can apply small changes so that the article will look completely different.

You can earn extra money without having any product of your own by just including your own resource box with a link to an affiliate program. So whether the reader clicks this link or your Adsense links, you are likely to earn extra money.

As you see, earning money online can be done quite easily.
