Whenever you use a search engine, you're asking the search engine to sort through the millions of web sites it has indexed, and try to find those sites that are related to your search words. Once the relevant sites are selected, the search engine will then rank these sites in order of relevancy — using a formula that varies for each search engine. As a website owner, there's a lot that you can do to improve the chances that a search engine will recommend your site. A few of the areas to focus on is content and your keywords.
