It means that your webpages are not yet crawled and indexed by search engine crawlers.

There are several reasons why a site might not show up in search engine results pages. Here are the most common ones:

-Google has not indexed your website yet
-Your website has "no index" tags
-Your website isn't optimized for search engine crawling
-Your website has been removed from Google [Deindexed or Penalized]

Just check once in terms of robots.txt. By mistake if your put no-index option means google bots will not crawl and index your website.
