On September 26th, Google announced about its new algorithm "Hummingbird". It was rolled out by Google about a month ago. The name "Hummingbird” is coming from "precise and fast". It helps Google to run their process in new and optimistically better ways.
The hummingbird is paying more attention on the meaning of each word in a query. It takes the whole sentence or conversation or meaning into the account and better focus on finding the right pages with matching words. For more details, visit here.
