Google overhauls search engine

‘Hummingbird’ update includes new formula

MENLO PARK, Calif. – Google has quietly retooled the closely guarded formula running its Internet search engine to give better answers to the increasingly complex questions posed by Web surfers.

The overhaul came as part of an update called “Hummingbird” that Google Inc. 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 Google’s 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 senior vice president for the company. He estimates that the redesign will affect the analysis of about 90 percent of the search requests that Google gets.

Any reshuffling of Google’s search rankings can have sweeping ramifications because they steer so much of the Internet’s traffic. Google fields about two of out every three search requests in the U.S. and handles an even larger volume in some parts of Europe. The changes could also drive up the price of Google ads tied to search requests if websites whose rankings are demoted under the new system feel they have to buy the marketing messages to attract traffic.

The search ads and other commercial pitches related to Web content account for most of Google’s revenue, which is expected to approach $60 billion this year.

Google’s renovations to its search engine haven’t triggered widespread complaints from other websites yet, suggesting that the revisions haven’t resulted in a radical reshuffling in how websites rank in the recommendations. The Caffeine update spurred a loud outcry because it explicitly sought to weed out websites that tried to trick Google’s search engine into believing their content was related to common search requests. After Caffeine kicked in, hundreds of websites that consistently won a coveted spot near the top of Google’s search results had been relegated to the back pages or exiled completely.

Hummingbird is primarily aimed at giving Google’s search engine a better grasp at understanding concepts instead of mere words, Singhal said.

The change needed to be done, Singhal said, because people have become so reliant on Google that they now routinely enter lengthy questions into the search box instead of just a few words related to specific topics.

With the advent of smartphones and Google’s voice-recognition technology, people also are increasingly submitting search requests in sequences of spoken sentences that resemble an ongoing conversation. That trend also factored into Google’s decision to hatch Hummingbird.
