Google Rolls Out Real-Time Search Tech
Google rolled out real-time search technology last month, offering searchers access to brand-new blog posts, Tweets and news items far faster than the five to 15 minutes it previously took Google’s Web crawlers to discover newly created items. To do this, Google has adapted its page rank technology and created new algorithms to keep results relevant.
While Bing, Cuil and other search engines provide the same type of results, Google claims to offer the most comprehensive real-time results by scanning news headlines, blogs, and feeds from Facebook, MySpace, Twitter, and other sources.
How do they determine what to display in search results? Well, it’s basically based on reputation. Amit Singhal, Google Fellow, states, “You earn reputation, and then you give reputation. If lots of people follow you, and then you follow someone–then even though this [new person] does not have lots of followers,” his tweet is deemed valuable because his followers are themselves followed widely. It is “definitely, definitely” more than a popularity contest.”
