This is from the Google webmaster tools section on site links. This is what you would see if you don't have any.
Sitelinks are additional links Google sometimes generates from site contents in order to help users navigate your site. Google generates these sitelinks periodically from your site's contents.
Because we generate sitelinks dynamically, this list can change from time to time.
Google has not generated any sitelinks for your site. Sitelinks are completely automated, and we show them only if we think they'll be useful to the user. If your site's structure doesn't allow our algorithms to find good sitelinks, or we don't think that the sitelinks are relevant to the user's query, we won't show them. However, we are always working to improve how we find and display sitelinks.
