For all of you asking how i did do that: Probably the secret is in the on page optimization and a good internal linking. Meta tags on every page is a MUST. Who says google does not care about metatags is an idiot. I really didn't do a lot of SEO job on the site lately, beside linking some internal pages with "nofollow" (TOS, about, contact, comment forms, privacy policy etc, really do not need PR juice) The strange thing is that they did not list in the sitelinks one category which have a rather good amount of backlinks from other sites.
lol, Its a new feature in G Sitemaps,All my sites have them. Check yours; Webmasters Tools > Links > Sitelinks.
I didn't linkbuild with nofollow. I put nofollow attrib on links to some of internal pages. Google doesn't need to follow my TOS, Privacy, etc. links in my footer, as well as "printer friendly versions" and "mail to a friend" and more.
But even if you have sitelinks, how do you pull the results up? I got sitelinks too but when i type my domain name in the search engine I don't see the sitelinks appearing anywhere
