Googles Algorithm RankBrain

Launch date: October 26, 2015
Hazards: Lack of query-specific relevance features; shallow content; poor UX

How it works: RankBrain is part of Google’s Hummingbird algorithm. It is a machine learning system that helps Google understand the meaning behind queries, and serve best-matching search results in response to those queries. Google calls RankBrain the third most important ranking factor. While we don’t know the ins and outs of RankBrain, the general opinion is that it identifies relevance features for web pages ranking for a given query, which are basically query-specific ranking factors.

How to adjust: Optimize content for relevance and comprehensiveness with the help of competitive analysis.
