Welcome to the Q&A Forum

Matt Cutts mentioned at SXSW that Google wants to take into consideration the quality of the experience ecommerce merchants provide and work this into how they rank in SERPs.  Here's what he said if you missed it: "We have a potential launch later this year, maybe a little bit sooner, looking at the quality of merchants and whether we can do a better job on that, because we don’t want low quality experience merchants to be ranking in the search results.” My question; how exactly could Google decide if a merchant provides a low and high quality experience?  I would image it would be very easy for Google to decide this with merchants in their Trusted Store program. I wonder what other data sets Google could realistically rely upon to make such a judgment.  Any ideas or thoughts are appreciated.
