Yahoo! has recently started a survey asking for votes and feedbacks for search results on Yahoo!. The users can give feedback on natural, free and organic search results. One sees in the screenshots of Yahoo! the survey asking 'How useful are the first two results below?'. There is point scale from 1 to 5. A similar survey was initiated earlier also by Yahoo! for PPC ads. In the PPC survey, people were asked to rate first five results.
