Michael Arrington at TechCrunch notes Google is testing a search results page format that encourages users to vote for the validity or value of each listing. A plus or minus symbol beside a listing pushes that listing up or down in overall results. Beneath listings, a comments section allows users to post reviews or personal comments about each reference.
Apparently the system, which is not visible in Canada, finds inspiration from the Digg social network which allows its users to vote for articles and other media posted by its enormous user-base.
It is unknown if individual user votes can or will affect Google’s overall sites rankings or if Google will ever roll such a system in to any of the search results it provides. Chances are, the number of votes necessary to have an impact will only be seen by the largest and most popular websites.
It is also worth noting that Google already has a user-vote system that has a direct effect on search engine rankings. Google tracks every click-through from its search engine results pages. By comparing the number of clicks a specific listing gets to the time each user spends at that URL, Google can determine if users really think a site is valuable or not.
