Search Engine Optimization
SEO (search engine optimization) is aimed at raising a website's rank on "natural" search engines such as Google, Yahoo, and Ask.com. Natural search engines rank websites based on site content, references to that site on other places on the internet, and a list of additional rules that are kept secret by the search engines. Knowing and leveraging those other rules is the job of SEO experts. Since three out of four people use a search engine to find new products and services, and half of Americans only look at the first page of results on a search engine, SEO is essential for websites.
