RankBrain is not new. In fact, Google has been using it for well over a year as part of their search algorithm. It is a further development of the Hummingbird-Update. Google Hummingbird was the first update that was developed in order to better “understand” the content of web pages. Google uses this machine learning artificial intelligence tool in processing billions web pages. Also, Search Experience ratings of websites by Google have moved to the forefront.
15% of all searches are “first searches”. RankBrain can give the right answer to queries that has been never asked before. That’s about 450 million searches per day!
