I will try and give you a few tips on writing articles for the many and various revenue sharing sites that appear online.  A couple of these sites, like Squidoo and Hubpages may already be known to you but there are many, many others.  The general idea is that you write an article and publish it on one of these sites – then the site owners put advertising on the page with your article and every time someone clicks on an ad or buys something from your page, you get a share of the money generated.  Sometimes (as on Hubpages) but not always(as on Squidoo), you need to have your own adsense account to receive this money.  If you write enough good-quality articles and use several different revenue sharing sites you can make a good income with this one technique alone.
