As with so many things Google, no one can say exactly what it is. Rank Brain is part of Google’s search algorithm. It’s an Artificial Intelligence (AI) system USED to process billions of web pages to help determine which results are the most relevant, in particular, queries that are new and not necessarily related to specific keywords (to really dumb down the EXPLANATION). There isn’t a way to optimize WEBSITES for Rank Brain other than to continue to focus on quality content because Rank Brain is LESS about keywords.
