      Currently – Major Online Retailer
      SD Semweb organizer, assistant SF organizer, etc
      Added goodrelationsrdfa onto some 900,000 item pages
      Looking at all kinds of backlinks from many e-tailers sites certainly demonstrated the necessity for structured data within web pages or a “less gameable” search solution.

      Rich Snippets yield increase in CTR (Click Through Rate)
      Initial claim – no change in search rankings
