Google June 2021 Core Update Impact Analysis

From a study by Amsive Digital of the global impact of this update to Google’s core algorithm, we can extract some interesting data. The first is that it has been an update that has disproportionately impacted YMYL websites (“Your Money, Your Life”, websites dedicated to medical or economic issues).

In the following graph we can see the change in the average total visibility of each category. This is intended to show how much each category has gained or lost visibility in relation to all other categories analyzed.

From these graphs we can easily extract that the categories that have gained the most visibility with this update have been those of “Reference Materials” (which includes sites that define words, dictionaries, wikis sites, public directories and question and answer sites) and “Computers and Technology”. On the other hand, those that have lost the most have been those of “Travel and Tourism” and those of “News”.

Among the domains that have gained the most, sites such as Wikipedia, Amazon, Cambridge, Facebook or IMDB stand out. Among those who have lost are Tripadvisor, Youtube, Yelp, CNN or Github.


Effect of the Google update on Sinapsis accounts

Regarding the accounts we manage at Sinapsis, we have observed that, after 10 days, 37.5% of the websites have experienced an upward trend, with the shopping sector standing out. 43.8% have suffered a drop in their visibility, especially the services sector. And, finally, 18.7% has remained stable.

It is important to remember that, as Google announced when launching this major update of the central algorithm, next month a second part is planned that, most likely, will offset the effects of this.
