You have probably more then likely heard of Adsense, or at least seen it in action, whether you know it or not. Basically Adsense is advertising offered by Google which they display beside the search results on Google. Also anyone who owns a website can also add Google Adsense advertisements to their website for additional income.
So this really isn’t a guaranteed do nothing or very little way that you can make money on the internet. To make this work you do need to put in some effort, and actually have a website which does get people visiting it. While having a small number of visitor’s can give a little income if done properly, you often really do need to have a reasonably good number of visitor’s to make this work.
The ads that are displayed are generally based on the content that you have on the page, so it is not always suited to every site, but the more content that you have on the site, the more chance the ads can be fitted in somewhere that will provide some revenue.
