This experiment lets you influence your search experience by adding, moving, and removing search results. When you search for the same keywords again, you’ll continue to see those changes. If you later want to revert your changes, you can undo any modifications you’ve made. Note that this is an experimental feature and may be available for only a few weeks.
The votes only affect the results you see. They do not spread out to the rest of the general search index. If will be very interesting to see if this voting system becomes a normal feature of the Google search engine. On one hand, it would let searchers have a bigger voice on the results they want to see and help clamp down on the search engine spams. Who knows, maybe my name will be voted back to number one! On the other hand, this can also be seen as Google admitting their algo isn’t as mindblowing as people think it is. With all the bitch slapping Google has been handing out, I can see why they want help sorting the mess they created.
