I just noticed theres an ability to promote sites on Google by clicking a green up or down arrow icon beside the result. How does this work? How many clicks will get my site to the top? Can I get lots of people to click promote it?
On the surface it is supposed to just customize your own search results when logged into your Google account. Some people believe that it may be part of a plan to use more user feedback to rank websites. There isn't really any proof that it affects rankings apart from your Google account. Google doesn't want to make it too easy to manipulate rankings.
