Google is known for bringing out numerous algorithm updates every year.
Whenever a new algorithm makes an entry or a major change is made to its existing algorithm by the search engine giant, webmasters and SEOs begin preparations for changing their strategies, lest their websites’ rankings or organic traffic get impacted.
2015 was no different with Google making a few significant changes to its algorithms Panda and Phantom. There were no fixes in its Penguin update, which was quite a surprise. The biggest overhaul came in the form of its mobile-friendly update or Mobilegeddon and the revelation of RankBrain, the machine learning AI system that plays a crucial role in ranking.
