Right now, Google uses a machine learning system called RankBrain. What does RankBrain do? Well, it basically processes every query handled by the search engine. At a recent meeting on machine learning, it was specified that Google might be somewhat puzzled by the whole idea of improving search results. Nevertheless, RankBrain can do more than just confuse. The system is all about “getting involved” and affecting rankings. The good news is the algorithm has proven to be extremely efficient because it is closely tied to page headlines.
A closer look at RankBrain
RankBrain is very much like a query refinement tool, and Google seems to be extremely fond of it. It uses it for nearly every search to understand that search. Then, it might alter the results, and the order of those results. Better described as a signal, the algorithm will soon enough be able to take down spam and block all black hat practices marketers use for SEO. It’s safe to assume that RankBrain is just the beginning of advanced machine learning. Considering that Google has been fighting spam for decades, it’s quite a surprise that the system is not 100% dedicated to black hat tactics. But it will get there, eventually.
