Google Hummingbird is a Google algorithm released in 2013. It incorporates semantic search into Google’s core search algorithm. Designed to be “precise and fast,” Hummingbird’s focus is on determining search intent through NLP and machine learning, and delivering the ability to achieve that goal on the search engine results page. Google RankBrain is part of the Hummingbird algorithm.

Hummingbird had a significant impact on keyword research, increasing the value and importance of long tail keywords.
