Google Adsense: This pay-per-click advertising program is probably the most popular and widely used of all internet advertising web publishers to earn money from their website.

You serve the Google text ads on your site and you get paid any time someone clicks on one of the ads.

Google allow websites to place these ads on their own pages, without requiring any technical coding experience, and the web site then gets a percentage of all the payments made to Google from clicks made via their site.

This is really easy and is a big money maker for a lot of people.

Affiliate programs : Affiliate programs are another great way for ordinary people to start making money from their website. The first step is signing up for an affiliate program, and the next step is adding affiliate ads to your Web pages. That's pretty much it.

Commission Junction: Commission Junction is premier network for affiliate marketing. With Commission Junction, you choose which affiliates’ ads to show on your site and then post their banners. This doesn't pay based on the number of impressions or the number of clicks, but rather someone would have to click on the banner, be taken to the affiliate website, and then either sign up or buy something from that website before you would be paid a commission. Obviously, the actual number of completed transactions are low but the commission on the completed sales are higher than other advertising methods. Commissions run anywhere from $1 to over $100 per completed sale or lead.
