Though Google declined to discuss the technology underlying the algorithm – a depressing break with the past – it did tell us that Hummingbird "makes results more useful and relevant, especially when you ask Google long, complex questions."
"Hummingbird pays more attention to each word in the query, ensuring the whole query is taken into account – so if a resulting page is a bit less strong in general, but it's the most relevant to your search terms, that's the result you'll get," a Google spokesperson told El Reg. "And if there are plenty of relevant matches to your search terms, Hummingbird does a better job picking the strongest page for you."
The algorithm was deployed several weeks ago and is involved in 90 per cent of Google's search queries, we understand.
Wonder if it will increase or decrease traffic to the average site ?
