[ed. See also: SEO Changed Forever in 2013.]
Google has a new search algorithm, the system it uses to sort through all the information it has when you search and come back with answers. It’s called “Hummingbird” and below, what we know about it so far.
What’s a “search algorithm?”
That’s a technical term for what you can think of as a recipe that Google uses to sort through the billions of web pages and other information it has, in order to return what it believes are the best answers.
What’s “Hummingbird?”
It’s the name of the new search algorithm that Google is using, one that Google says should return better results.
So that “PageRank” algorithm is dead?
No. PageRank is one of over 200 major “ingredients” that go into the Hummingbird recipe. Hummingbird looks at PageRank — how important links to a page are deemed to be — along with other factors like whether Google believes a page is of good quality, the words used on it and many other things (see our Periodic Table Of SEO Success Factors for a better sense of some of these).
Why is it called Hummingbird?
Google told us the name come from being “precise and fast.”
When did Hummingbird start? Today?
Google started using Hummingbird about a month ago, it said. Google only announced the change today.
What does it mean that Hummingbird is now being used?
Think of a car built in the 1950s. It might have a great engine, but it might also be an engine that lacks things like fuel injection or be unable to use unleaded fuel. When Google switched to Hummingbird, it’s as if it dropped the old engine out of a car and put in a new one. It also did this so quickly that no one really noticed the switch.
When’s the last time Google replaced its algorithm this way?
Google struggled to recall when any type of major change like this last happened. In 2010, the “Caffeine Update” was a huge change. But that was also a change mostly meant to help Google better gather information (indexing) rather than sorting through the information. Google search chief Amit Singhal told me that perhaps 2001, when he first joined the company, was the last time the algorithm was so dramatically rewritten.
What about all these Penguin, Panda and other “updates” — haven’t those been changes to the algorithm?
Panda, Penguin and other updates were changes to parts of the old algorithm, but not an entire replacement of the whole. Think of it again like an engine. Those things were as if the engine received a new oil filter or had an improved pump put in. Hummingbird is a brand new engine, though it continues to use some of the same parts of the old, like Penguin and Panda.
