Every year, Google makes hundreds of updates to its various algorithms; either to enhance the ranking software, penalize sites with erring backlinks and generally improve user search experience.
Some of these updates are announced ahead of time, while others fly under the radar- like an impromptu audit. Whichever it is, many sites usually end up with a weakened SEO ranking after a Google algorithm update. This leaves webmasters scurrying to make amends and reinstate their websites in the aftermath of the exercise.
The usual suspects are three major algorithms; Panda, Penguin and Hummingbird (although there are dozens more). As SEO-copy experts, we are already familiar with the functions and effects of these three, so we create content accordingly.
But in October 2015, a new sheriff came into town and changed the structure of Google’s ranking process as we knew it. That sheriffwas Rankbrain.
