Search engine optimization (SEO) is the art and science of publishing and marketing information that ranks well in search engines like Google, Yahoo! Search, and Microsoft Bing. If you run into any new jargon while reading this Knol consider looking up their definitions using the Search Engine Marketing Glossary.

By default, many search engines show only 10 results per page.  Most searchers tend to click on the top few results. If you rank at the top of the Search Engine Results Page (SERP), business is good, but if you are on the second or third page you might only get 1% of the search traffic that the top ranked site gets.

The two most powerful aspects of search engine marketing are:

users type what they want to find into search boxes, making search engines the most precisely targeted marketing medium in the history of the world
once you gain traction in the search results the incremental costs of gaining additional exposure are negligible when compared with the potential rewards, allowing individuals and small businesses to compete with (and perhaps eventually become) large corporations

While many people consider SEO to be complicated, I believe that SEO is nothing but an extension of traditional marketing. Search engine optimization consists of 9 main steps:
market research
keyword research
on -page optimization
site structure
link building
brand building
viral marketing
