What is RankBrain?

Nov 16th, 2015

RankBrain’s been getting a lot of media exposure recently, but it’s actually been part of Google’s core algorithm for quite a while


RankBrain is a machine-learning artificial intelligence (AI) system developed by Google to help process its search results. More specifically, it’s used to interpret the meaning of queries Google’s never encountered before (which account for around 15% of Google searches every day), ‘learning’ from previous data to inform current decisions.

What does this mean for search marketers?

We’ve seen search marketing evolve over the past few years to shift away from an emphasis on keywords, towards semantic relevancy, quality content, and overall user experience as Google continues to refine its techniques for providing ever more relevant, useful results.

RankBrain is best viewed as the next natural step in that process.

Any improvement to accuracy can only be a good thing…

Whether your strategy focuses on organic search (SEO), paid search (PPC), or a combination of techniques, any improvement in the accuracy of Google’s results will allow better targeting and more highly-qualified clicks on your ad or organic link, and ultimately improve the effectiveness of your campaigns.

And, as Google gets slicker at handling very specific queries, businesses that regularly update their websites with useful and detailed content will see an even greater return on their investment.
