The implications of how Google understands user intent and how it uses that information to rank sites is very useful for developing a winning content strategy. The following are insights developed by studying patents and research papers published by Google itself.
How Does Google Ranking Work in 2019?
Google uses a variety of factors in its algorithm to determine what results will be the most helpful for the user. It also uses latent semantic indexing, which uses search intent as an indicator of what results are the most relevant.
Google built its current algorithm around RankBrain, a machine learning (AI) algorithm Google uses to help sort and improve the search results.
