Google not recognising my site

ok, hope you help me with this

I am uploading an old magazine to my site, I want it to share with latin people specially because is in spanish, but when I put my site name of omeka on google is not showing up!!! same happens at my library with an older version, the computing guy sais is free on the internet but is not accesible from google

what are we doing bad?

If I'm following you right and you are typing the name of your site in the Google search box, it seems likely that Google is just returning search results that its ranking algorithms put higher.
