It's not indexed by the search engine. So unless you are putting quote marks on your search, you will come up with something. Most times, when I search a domain on Google, there will be domain valuation sites that come up with information about the domain.
It means your website havent been indexed by search engine bots yet. Please make sure that you are not blocking using robots.txt file & you dont have "noindex" tag in the page source as well.
It just means that your keywords have not been indexed for your site yet. Get your name out there. Use blogs, forums, Facebook, Twitter, things like that to drive more traffic to your site. Get back links. You will slowly start to get ranked higher and higher. Good Luck to You.
