Today, webmasters earn because of the following strategies they use to monetize their websites:

* Pay Per Click (PPC) programs allow them to display contextually relevant ads on their web pages and they earn as much as $50 every time a visitor clicks on such ads. The visitors don't have to buy anything; they just have to click on the ad blocks.

* Affiliate programs allow webmasters to pre-sell items on their websites. These items are related to the subject of their website. They are only tasked to pre-sell these items. The actual sales process will be carried out by the affiliate merchants. And for every successful sale the webmasters manage to refer to the program, they earn a commission that can total to as much as 95% of the selling price. There is no limit as to how many affiliate programs a webmaster can join.

* Once the website achieves a high page rank, it can sell advertising space for a variety of parties. It can even sell link space, which is a hot commodity, if the website has a page rank score of 4 or higher.
