Getting sitelinks for website

I used the search, but couldn't find anything useful, so here it is:

I have a few sites, some of them PR4 and on #1 for some searches. But none of them has these sitelinks. Does anybody have tips or ideas on how to get these. Because Google mentions that the structure needs to be correct, but I haven't got the slightest idea what they want with that.

Would that mean that I have to create subdomains for the most usefull pages of my domain, and place them in order of importance in a top-right-menu-thingy?

Sorry if this sounds like a n00b question, I try to make it sound like I know what I'm talking about

 

I came across this old article, maybe everything is in it. But it's 1 year old I guess, and the sitelinks feature has been updated recently.

This is the Authority thing that Google uses for Authority sites. I don't believe that this is anything that we can have control over, and is something that Google will do, based on the authority and importance of each site.

Creating a much clearer and organised navigation section to your site should help, as will creating an xml Google sitemap.

Your best bet would be to continue working on your site, keeping updated and adding fresh and unique content on a regular basis.

 

Site links consume a lot of screen space for just 1 site, methinks they are probably restricted to the sites that Google holds in the highest esteem for that particular query

 

I took a look at a number of Websites that had sitelinks and wrote a brief article on the similarities of sitelinked Websites. The article url is:

It is true that sitelinks appear for mostly authority Websites. But most sites can be an authority for their own business name. It's all about the site structure and Google figuring it out. Once Google does, you can start managing sitelinks in webmaster tools.

 

I think, a good internal linking structure along with back links from prominent sites (The one's Google consider prominent), could possibly be the benchmarks.
