Most engines "spider" the Web looking for new pages to add to their database or index. You can wait for one of these spiders to locate your site but you could be in for a long wait. The better approach is to go to their site (or a site submission service) and tell them about your new Web site. Once your pages are added to the index, people can do a search on the Internet for various keywords to find pages that "best" match their search criteria. Appearing within the first few pages of the search is critical to people finding you. These matches will be ranked or positioned in order of importance. The exact rules they use to rank pages for relevance are generally kept a secret and change often. However, many of these rules can be determined through simple observation.
