Google unveils major upgrade to search algorithm - Pdf Slider

Google has unveiled an upgrade to the way it interprets users` search requests. The new algorithm, codenamed Hummingbird, is the first major upgrade for three years. It has already been in use for about a month, and affects about 90% of Google searches. At a presentation on Thursday, the search giant was short on specifics but said Hummingbird is especially useful for longer and more complex queries. Google stressed that a new algorithm is important as users expect more natural and conversational interactions with a search engine - for example, using their voice to speak requests into mobile phones, smart watches and other wearable technology. Hummingbird is focused more on ranking information based on a more intelligent understanding of search requests, unlike its predecessor, Caffeine, which was targeted at better indexing of websites.
