RankBrain
RankBrain is a self-learning algorithm developed by Google that is an important part of determining the order of results of search queries. It helps Google edit search results and provide more relevant search results for users. In a 2015 interview, Google commented that RankBrain is the third most important factor in the ranking algorithm after backlinks and content.
When RankBrain sees a word or phrase that it is not familiar with, the algorithm can guess which words or phrases might have a similar meaning and filter the result accordingly. This increases the efficiency of handling never-before-seen searches. These are sorted into word vectors that are close together in terms of linguistic similarity. RankBrain tries to map this query into words (entities) or clusters of words that have the best chance of matching. Therefore RankBrain tries to guess what the intention of the search query is and saves the results to ensure better user satisfaction.
