In a May 1 video on Google Webmaster, Matt Cutt provide more details on how Google uses 'human raters' as part of their algorithm.

In the video, Cutts specifically says these quality raters have no direct impact on the Google search results. He explains how what they do is used in the overall Google search quality process:

  • Google Quality Raters rate URLs if they are good, bad, spam and other classifications
  • Then when the Google engineers changes the algorithm
  • The engineers can run queries to see what changes
  • Based on the Quality Raters ratings, an engineer would want to see better results Google Quality Raters (Human raters)ranking higher in their new algorithm compared to before
  • Then engineer does a side by side (blind taste test) directed to the Quality Raters and the Raters says I like left side or right side
  • The engineer then can see those test results and if the results to look better overall based on those rating they might want to expand on it
  • Then Google sends out a live test to a small percent of users and run the tests on live (non raters) people
