What is Hummingbird?
Google Hummingbird (2013) is a major search algorithm update aimed to improve the accuracy and relevance of search results by better understanding the context and intent behind search queries - particularly more conversational or complex search terms.
Unlike earlier algorithms that focused primarily on individual keywords within a search query, Hummingbird considers each word but also how those words make up the entire query.
The goal is to match the query with results that are the most relevant to what the user is trying to find out.
