Abstract: You may have known that SEO (Search Engine Optimization) plays a crucial role in a web site. If you don't optimize your web site, you are doomed to fail in making money online since you can't get a good web site traffic. And as we all know, most of the web site traffic comes from the search engines that help its users or the web surfers find the information they are searching for in the internet.

Search Engine Optimization is the process of increasing the number visitors to a web site through natural or organic search engine listing in Googe, Yahoo, MSN, Ask.com (formerly AskJeeves) and others. It focuses on improving the rank of a web site in the Search Engine Results Page (SERP) when a web surfer use the search engines to search for something.
And if your web site lands within the first 2 pages of the result page, more users will be able to see your web site. More exposure means more visits or more clicks to your site, especially if your web site looks interesting or intriguing to the search engine users or web surfers. As a result, you can make more money from it.

You must understand, however, that search engines like Google and Yahoo also have their own businesses. The main business of them is to sell their advertising and other business programs. That's to say, the goal of the search engine is to attract more users by providing them a list of quality contents they want and need.
In return, the users or web surfers will surely prefer to use the search engines that could provide a quick list of quality web sites or information to their search queries. They will stay away from search engines that are slow and provide poor web sites. Moreover, the search engine users or web surfers do not like visiting web sites that are not interesting.
So, in order to achieve success, you must convince the search engines that you deserve a high rank in their SERPs by complying with the requirements of a quality web site. Besides, the content in your website should be interesting and meet the demand of visiters.
