Google[3] Hummingbird is a search algorithm[2] introduced by Google in September 2013. This tool is significant because it was the first major update since the Caffeine upgrade in 2010. Hummingbird’s name is indicative of its speed and accuracy. It’s designed to focus on the context of words in a search query, understanding the relationships between keywords to deliver more relevant and human-like search results. This algorithm doesn’t just match pages based on individual words, but on their meaning, emphasizing page content and authority. This change affected search engine optimization[1] practices, promoting natural language use, technical features, high-quality content, long-tailed keywords, synonyms, and effective use of on-page elements.
Hummingbird is the codename given to a significant algorithm change in Google Search in 2013. Its name was derived from the speed and accuracy of the hummingbird. The change was announced on September 26, 2013, having already been in use for a month. "Hummingbird" places greater emphasis on natural language queries, considering context and meaning over individual keywords. It also looks deeper at content on individual pages of a website, with improved ability to lead users directly to the most appropriate page rather than just a website's homepage.
The upgrade marked the most significant change to Google search in years, with more "human" search interactions and a much heavier focus on conversation and meaning. Thus, web developers and writers were encouraged to optimize their sites with natural writing rather than forced keywords, and make effective use of technical web development for on-site navigation.
