Are you not being listed properly or at all on the world's most popular search engines? You need to optimize your website with S.E.O. ( Search Engine Optimization ). This will make sure you have meta tags enabled and properly formatted, a sitemap that search engines use to find all of the pages on your website, and keywords placed throughout your site that the search engines can spider to increase your natural listings. There are many services out there that will help you perform this task of marketing your site to the web. For more information, you may contact an XMLA Team member to learn about why you need S.E.O. to get you listed properly. 
Yahoo does not automatically include your website in its directory. You must manually submit it to http://search.yahoo.com/info/submit.html.
