I worked for Leapforce for a while doing this sort of rating work using Google's guidelines. The guidelines were linked elsewhere in this thread and, at a glance, they are the same ones I used: https://static.googleusercontent.com/media/guidelines.raterhub.com/en//searchqualityevaluatorguidelines.pdf https://static.googleusercontent.com/media/guidelines.raterh... If you're doing something that would skew the results to favour a certain brand, you'd be going against Google's guidelines and your contract would be terminated quickly. I found the review process of my results to be fairly stringent; they were reviewed frequently to ensure I was staying within the guidelines, and I was told even about slight deviatiations.
