Have you noticed some changes?
Quote:GOOGLE says it recently overhauled the closely guarded formula that runs its influential internet search engine to give better answers.
The overhaul came as part of an update called "Hummingbird" that Google has gradually rolled out in the past month without disclosing the modifications.
The changes could have a major impact on traffic to websites. Hummingbird represents the most dramatic alteration to its search engine since it revised the way it indexes websites three years ago as part of a redesign called "Caffeine," according to Amit Singhal, a company vice president. He estimates that the redesign affects about 90 per cent of the search requests Google gets.
