Google has announced that they are using a new “machine learning” technology called RankBrain. As with any big change that Google makes, people are wondering how it will affect the way we view the web, and how our websites are viewed by others. Through this blog post we hope to explain in layman’s terms how RankBrain fits into what we already know about Google, what machine learning is, and what all this means for you.
First of all, where does RankBrain fit in to Google’s grand scheme?
You’re probably familiar with the fact that Google uses an algorithm, a secret formula for delivering search results. What you may not know is that this algorithm (called Hummingbird) is made up of many unique parts each serving a different purpose, and RankBrain is the newest part. Here’s how they work together.
Google uses hundreds of different “signals” to determine how to answer your search queries. Each of these signals are like clues, such as the region where a user is located, or the PageRank of a website. To find these clues, Google’s engineers have designed tools that help sniff them out and apply them to your search query so that accurate results can be delivered. RankBrain is one such tool, but RankBrain’s signal is a bit different from the rest of these. Rather than being designed to look for a specific type of clue, RankBrain was designed to learn about and interpret conversational language so that it can better access the meaning behind a phrase or sentence, this is the “machine learning” aspect of Rankbrain.
So what is “Machine Learning” exactly?
A traditional Computer is not very smart, everything the computer does has to be taught to it by a human being. A machine learning computer on the other hand, can teach itself to do things. Machine learning is essentially a type of artificial intelligence, though this is not the level of sophistication that you would see in a typical science fiction plot, so you can lay your robot uprising fears to rest, for now.
What’s an example of what RankBrain does?
Before RankBrain, if you typed in a long and complicated search query Google would probably pick and choose from keywords and other clues in your query and serve you up the best answer it could. This system worked fairly well, but the way we search is evolving to be more conversational, especially with the rise in mobile technology; just think of any time you’ve asked Siri a question.
That’s where RankBrain comes in. RankBrain is able to better understand things like colloquial terms, and conversational dialogue that complicates queries, and it does this by comparing and connecting them to shorter more common queries it has dealt with in the past. In other words, RankBrain is able to make assumptions about what you’re asking for based on what it has learned from past searches. The result of this knowledge is that Google can leverage the answers for the more common query to help improve what it provides for the complicated one.
How does this affect you?
Let’s cut to the chase – it has been confirmed by Google that in the short time since its launch, RankBrain has become the 3rd most important ranking signal of their algorithm (they declined to list the first two). In short, it plays a major role in determining who sees your site, and how highly your site is ranked. Now, to leverage what you now know about RankBrain to stay ahead of the competition:
