Let's say you have a website that is akin to the YellowPages. It is a listing of lots of other companies.
Should you place microdata about each company on each company listing page? Or should you just put Microdata about the "Yellow Pages"?
Do I put all the Microdata on the page to be about Joe's Florists, or the parent website, Lots O' Companies?
I'm not quite sure how Google wants this data? On a site level, or a page content level?
