The second, and perhaps more exciting, component of Hummingbird was the introduction of contextual search. Until Hummingbird, search engines typically interpreted queries using what it identified as the most important keywords from a search. But with Hummingbird’s introduction, Google has begun to look at the relationship between terms to interpret context.
Many considered Hummingbird a natural evolution both of Google’s development and of the proliferation of mobile devices. After being in business for 15 years, Google’s developed an incredibly rich and sophisticated Knowledge Graph (or major database of all the information that it’s collected). As more and more users search on mobile devices, searches are evolving from short keyword driven inquiries to being structured the way we naturally speak and ask questions. Hummingbird is helping to ensure that Google is poised to understand and meet that demand.
