Who can tell me waht is "Microformats, microdata, or RDFa code" the whole context is --Microformats, microdata, or RDFa code: Events, reviews, people, and more can be tagged to appear as part of a search listing. You can see these in action with upcoming shows on MySpace band pages, the star ratings on Yelp restaurant listings, and a sample of a person's friends appear with some Facebook profiles. ----Does this have something to do with SEO? and how?
