According to the Search Engine Roundtable, Western webmasters recently revealed signs of yet another unconfirmed update to Google’s ranking algorithm.
Changes to the search engine are discussed on Twitter and on the WebmasterWorld and Black Hat World forums. Some webmasters talk about the traffic growth that arose as a result of the ranking algorithm update. Other specialists, on the contrary, note a decline in attendance. However, both of them unanimously argue that the same changes can be traced, both in the case of desktop issuance and mobile.
The likelihood of an update being made was also recorded using SERP monitoring tools.
At the moment, there is no official data as to what caused such changes.
