Google will begin incorporating Google+ results into its search algorithm. They call it: Search Plus Your World.
Google today unveiled Search Plus Your World – an initiative, one reporter noted, that marks "one of the biggest changes [Google] has ever made to its search results." Broadly speaking, Search Plus Your World makes searches more "social," which is to say that search results, from here on out, will take into account not just data and factoids, but also relationships between users.
"Search is pretty amazing at finding that one needle in a haystack of billions of webpages, images, videos, news and much more," Google's Amit Singhal wrote in a blog post today. "But clearly, that isn’t enough. You should also be able to find your own stuff on the web, the people you know and things they’ve shared with you, as well as the people you don’t know but might want to... all from one search box."
Search Plus Your World piggybacks on Google+, Google's relatively young – and relatively popular – social network. (It's worth noting here that users can turn off personal results with a single flip of the toggle switch.)
