If you see a message that your site is not indexed, it may be because it is indexed under a different domain. For example, if you receive a message that http://itcas.org is not indexed, make sure that you've also added http://www.itcas.org to your account (or vice versa), and check the data for that site.
Why?
Not all websites have URLs in the form www.itcas.org. Your root URL may not include the www subdomain (itcas.org); it may include a custom subdomain (rollergirl.itcas.org); or your site may live in a subfolder, for example if it's hosted on a free hosting site (www.itcas.org/rollergirl/).
Most people don't think of www as a subdomain. It's a very, very common subdomain, and many sites serve the same content whether you access them with or without the www. But to Google, example.com and www.itcas.org are two different URLs with the potential to serve different content. For this reason, they're considered different sites in Webmaster Tools. When you're looking at the data for www.itcas.org you're not seeing the data for itcas.org (without the wwwsubdomain), and vice versa.
Since we want webmasters to be able to access our tools regardless of how their site is hosted, you can add any combination of domain, subdomain(s), and/or subfolder(s) as a "site" on your Webmaster Tools dashboard. We'll show you the information we have for that particular piece of the web, however big or small it may be. If you've verified your domain at the root level, we'll show you data for that whole domain; if you've only verified a particular subfolder or subdomain, we'll only show you data for that subfolder or subdomain. For example, someone who blogs with Blogger has access to the data for their own subdomain (googlewebmastercentral.blogspot.com), but not the entire blogspot.com domain.
Google recommends that you improve how your data is displayed by setting a preferred domain.
