Hey, im stuck so i thought I would ask some pros! When you type youtube into google for example, and below the url- Cached - Similar pages - Note this There is two rows of links eg: A Vision of Students Today The Music Video Categories History Channels Comedy Featured Videos Community My question: How?? I have tried various sitemaps, and tweaked and changed, and still cant do it, how can you do this? How can you have you sub directories/sections listed below like this? Thanks
Sitelinks are completely automated, and it shows only if Google think they'll be useful to the user. If your site's structure doesn't allow Google algorithms to find good sitelinks, or Google doesn't think that the sitelinks are relevant to the user's query, google won't show them.
take a look at How does Google compile the list of links shown below some search results? for more info on what manish said.
