How does Google determine which content ranks where on the search engine results page (SERP)? That question is at the heart of SEO, and it’s also important to content marketing. Answering it is, truthfully, close to impossible; Google’s algorithms are complicated, and ever-changing. There are a lot of factors in play, and the way Google balances and prioritizes them is somewhat veiled.
With that said, Google has been clear about one thing: RankBrain is one of the most important of all ranking factors. In fact, Google has stated that it’s in the top three. So, if you want to write content that ranks well, you have to know what RankBrain is—and how to appease it.
