What is the RankBrain algorithm?
The RankBrain is an AI (Artificial Intelligence) program built to help Google understand search queries. It helps Google to process search results and provide more relevant search results for users. It embeds a wide range of written languages into mathematical entities, named vectors, that the machine can understand. If RankBrain faces a sentence that it does not know, it can guess the meaning with similar sentences or words and filter the result accordingly, making it more accurate for the new tries.
