RankBrain

Another notable Google algorithm update is known as RankBrain. In October 2015, Google announced that machine learning (Artificial Intelligence) had been deeply ingrained into Google search and is supposedly the third most important search ranking factor. Going beyond just keywords, Google is trying to understand the diverse ways in which users turn to search engines to answer their queries, for which SEO is always trying to adapt and adjust to keep clients at the top of the organic rankings.
