Definition
Google Hummingbird is a complete overhaul of Google's search engine launched in August 2013. Unlike Panda and Penguin, which are filters added to the existing algorithm, Hummingbird represents a full replacement of the algorithmic core. Its main innovation is semantic query understanding: rather than focusing on each keyword individually, Hummingbird analyzes the overall intent behind the search. This algorithm laid the groundwork for conversational search and particularly improved result relevance for long, complex queries (long-tail).
Key Points
- Complete algorithm overhaul, not just a filter
- Semantic understanding of search intent
- Foundation for conversational and voice search
Practical Examples
Conversational query
For the query 'what is the best Italian restaurant near me open on Sundays', Hummingbird understands the complete intent instead of searching each word separately.
Semantic search
An article thoroughly covering 'how to improve your site speed' also ranks for 'make my site faster' thanks to semantic understanding.
Frequently Asked Questions
