What does it mean if nothing appears on doing search on the domain?

It means the domain may not have a sitemap generated, and/or was not submitted to the search engines or web/blog directories. Try creating a sitemap for the domain name, and submit it to Google or Bing to improve traffic to your site.

While search on your domain on Search engines and if nothing appears then there are three possibilities.

• May be the site is banned by search engines
• May be no index by search engines
• Some canonical issues
