Sitelink for forums?
 

Hello I am curious how to setup a forum where your forum categories could be counted as site link on Google?

Here is an example.

For the Google search for the site Webmaster-Talk it has its forum categories as sitelinks

It is structured as web-design-talk/ for the Web Design Talk forum category.

I was under the impression that a site link is a file with a / and an index file.

So I am curious if anyone knows how to do this?

Thanks

Chris

You just have to build links to your forum for google to think of you as an authoritative site
you'll than get sitelinks under your search result


How does Google compile the list of links shown below some search results?

So get links to the forum categories?
