Google enhanced its search results with this information.
Knowledge panels, boxes, and carousels can appear whenever
people do a search for one of the billions of entities and facts in the
Knowledge Graph.
The next step in Google’s next generation of search came in
September 2013 in the form of Hummingbird, a new algorithm
designed to better address natural language queries and
conversational search.
With the rise of mobile (and voice search), Google needed to
completely rebuild how its algorithm worked to meet the needs of
modern searchers.
Hummingbird was considered to be the biggest change to Google’s
core algorithm since 2001. Clearly, Google wanted to deliver faster
and more relevant results, especially to mobile users.
