Google Sitelinks

Google Sitelinks are little sub-listings format that appear under the first result in the search result (usually when searching for brands).
Sitelinks can be a valuable reputation enhancer, and also a way to control a greater area of the search results page. Sitelinks can help the searching process in two ways: get a better understanding of what the site is about, take a shortcut from Google to the page that interests them directly.
In Google’s own words:
“”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.””
In addition, There is a very little control over sitelinks there is always have the option to block sitelinks which site owners don’t want to show in search result.
Here’s an example of a Sitelinks listing:
