How content marketers and SEO experts can optimize for RankBrain

Around October 2015, Google announced it would be using artificial intelligence to help deliver its search results. This machine-learning AI system is called RankBrain. Since RankBrain uses machine-learning AI, it learns by itself, consuming web pages and search queries by the second with the intent of delivering the best and most relevant results to users. You need to understand that this is an addition to Google's algorithm and not an algorithm update such as Hummingbird, Penguin, etc. In fact, it is reported that RankBrain is now Google's third most important signal contributing to search queries and results.
