Here is Google’s definition and explanation on Sitelinks:
The links shown below some sites in our search results, called Sitelinks, are meant to help users navigate your site. Our systems analyze the link structure of your site to find shortcuts that will save users time and allow them to quickly find the information they’re looking for.
We only show Sitelinks for results when we think they’ll be useful to the user. If the structure of your site doesn’t allow our algorithms to find good Sitelinks, or we don’t think that the Sitelinks for your site are relevant for the user’s query, we won’t show them.
At the moment, Sitelinks are completely automated. We’re always working to improve our Sitelinks algorithms, and we may incorporate webmaster input in the future.
After the initial analysis, some SEO experts reckon that the following factors are why Sitelinks being displayed:
- Site Traffic: The higher traffic a site is getting, the better chance its Sitelinks will be displayed.
- Google Toolbar: The more often the site is bookmarked on Google Toolbar, the better the chance its Sitelinks will be shown.
- SEO friendly links at the top of a web page’s will help boosting the chance of getting Sitelinks of the site shown.
