So, I have always heard that site links in the google search are a very good thing..

I was pretty surprised that a site I have with about 40 pages has 5 site links listed. the site doesn't get super great traffic, but is my #1 earner by far and ranks well for tough keywords.

So, my question is - How does google determine what sites need site links? Is it traffic? Rankings?

Also, for anyone that has a site with site links, Do these sites convert better? Have better rankings? Etc.

The pages that have been given site links are some of my lowest traffic pages in this site, so I'm clueless as to how google decides which pages to assign them to.
