Google updates its search algorithms:
The new algorithm is meant to keep up with longer, more advanced search queries that come through Google. Instead of simple keyword queries, Google is working to accommodate questions on par with what users might ask their friends off the Internet. (e.g. “Tell me about Impressionist artists.”) Hummingbird is the company’s most significant algorithm change since Google switched to “Caffeine” back in 2010, says Singhal. Google also showed off more advanced voice queries, in which your computer or tablet will answer back to you. “Voice will be fundamental to building future interactions with the devices [we use],” says Singhal. Users can ask Google to compare two items, generate a list of songs from a particular artist, or pull statistics about the Eiffel Tower and receive a voice response.
