How to optimize for RankBrain?
In October 2015, Google unveiled its new algorithm called RankBrain, which uses artificial intelligence to filter the most relevant results and thus have a more exceptional ability to answer user questions.
Users no longer have to think with what words to perform the search. Actually, just talk directly with the machine. Therefore, in order for our content to position themselves better, they have to be answers to the problems of people written naturally.
The key is to write as if you were talking to someone in front of you, in a colloquial and clear way. RankBrain likes this content because it knows it is easier for most audiences to understand.
