If November was a very busy month in terms of updates to the Google search algorithm, this December it seems that it will not be less. And is that on Tuesday the 1st we could already detect a possible update that Google has not updated. But the most common algorithm monitoring tools indicated important variations on that date that continue until today, for now.
Perhaps the most notable is Cognitive SEO, where we observe a disturbance that begins on December 1 and begins to reach its peak today.

Regarding our accounts, we have been able to observe that 49% of the websites we monitor have shown an upward trend after the search algorithm update. On the other hand, 14% have not been affected and 37% show a downward trend that we will endeavor to correct.
