If you create a site on our system and then you try to look for it on a search engine you wont find it. This is because the search engine does not know your site exists yet and it is not listed on the search engine. In time the search engines will find your site and possibly add it to the search engine, however it is much easier and faster to submit a request to the search engine / engines to add your site. This tutorial here will show you how best to do that.
