I strongly disagree with this premise. I would suspect real branding, PR, and marketing data would show that press reviews influence branding and sales 10-1 over consumer reviews.
(although consumer reviews can mean lots of things. It can mean a friend recommends, or a consumer does a deep video review online, or it could mean an anonymous person gives random feedback.)
I guess, I have two questions: 1. Can you substantiate that original premise with more than a poll or survey, but actual market research? 2. Do you think incentivized reviews will instantly remove any credibility those reviews may have carried in the first place?
