Search Algorithm Behind Google Search Technique

Google has a 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 search algorithm that Google is using, one that Google says should return better results. Google told us the name come from being “precise and fast.” Google started using Hummingbird in the mid of 2013, it said. 

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. 

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

The new engine is using old parts?

Yes. And no. Some of the parts are perfectly good, so there was no reason to toss them out. Other parts are constantly being replaced. In general, Hummingbird — Google says — is a new engine built on both existing and new parts, organized in a way to especially serve the search demands of today, rather than one created for the needs of ten years ago, with the technologies back then.
