RankBrain is the now latest addition to Google’s Hummingbird algorithm. Rank Brain AI has outguessed Google search engineers for by 10% when asked to view pages that should rank on top of the search results.
RankBrain is an Artificial Intelligence Program
The AI program was designed by hundreds of Google engineers and the program embeds vast amounts of written language into mathematical entities which are called vectors so that the computer can understand. Most known ranking factors such as keyword use, links, and domain authority are individually created by people. RankBrain, in contrast, is a conglomerate ranking factor that the search engineers designed and then set free to draw its own conclusions about what should be ranked and how. For words or phrases it does not recognize it is able to guess at what words and phrases user intent is looking for and show appropriate search result query results.
