You typically fill in your URL and sometimes your e-mail address. They may take weeks and even months to index your Web site. We believe that manual submissions should be made to the major search engines. Be careful, some promotion services request personal information that can result in Spam and others do a poor job of submitting sites. Microsoft, LookSmart and Yahoo now charge for new submissions.
Some search engines have spiders or robots that travel the Internet and add sites.
However, they are very slow to arrive at unregistered sites. Even if they spider your site, they may spider the incorrect pages. A site that is improperly designed will seldom be found by prospective customers. The situation is similar to adding a new phone and hoping someone will find the number. These Meta tags work in combination with page text to inform search engines about their content.
