Web visitors generally use search engines to find sites matching their search criteria. The visitor enters words or phrases in the search area, and the search engine produces a list of related sites. The search engine becomes aware of a new site to visit and index when that site is submitted. Submitting your URL to a number of search engines increases the odds of potential customers finding your site through traditional online searches. You can further increase your chances of being found through a search by adding relevant keywords to your home page title and text.
Search engines are one of the least expensive and most successful forms of online marketing.
If you're serious about reaching new visitors, submitting your site to search engines is essential. You want to keep your web site registration current. Link Pages move older links to the bottom of the list, and resubmitting puts you back on top. Search engines have a tendency to drop or lose sites from time to time. Resubmitting monthly ensures your site won't get lost.
