Links under Rich Snippet Text?

[Modbargains]

I was curious how certain sites have links under their rich snippet texts? is it from google authorship?

found it. it deals with the sitemap. It's auto generated. I also think it deals with search result and a high CTR.

I thought this was about micro-formats and schema.org content but after some looking around I'm not sure now. There doesn't seem to be a consensus on how those links appear, but I haven't been able to find anyone discussing it after 2006 or so. This was the best writeup I could find:

Basically it seems to be that if Google has 'learned' your site thoroughly they'll arbitrarily decide to shove those links in there. The discussions I can find don't really suggest a way to do it, and some express frustration over controlling which links go there. The impression I get though is:

• Google SiteMaps are probably involved

• The sub pages are usually linked to heavily

• The sub pages are usually pretty 'clean', e.g. full of content

I guess it's comparable to what Google classifies as sub-results when you search for your brand name but other than that it's a mystery to me.
