Google explains the “core” algorithm

In 2016, Google’s Andrey Lipattsev explained the “core” algorithm.

This happened following the news about Panda becoming part of Google’s core algorithm. SEOs wanted to better understand what being part of Google’s core algorithm meant.

Put simply, it meant that an algorithm is consistent enough that Google doesn’t have to worry about it because it’s been tested, works the way it should, and won’t require many changes in the future. As Lipattsev explained:

It is less about the functionality, which means it probably doesn’t change that much over time, and it is more about how we perceive it, in the context of the algorithm. Do we still think this is an experimental thing, it is running for a while and we aren’t sure how long it will last? Or is it like PageRank, it is part of it, it will always be there, at least in the foreseeable future and then probably call it in certain context part of the core algorithm.

So now when you hear about the latest Google core updates, hopefully you better understand what Google’s core algorithm means.
