Google’s November Core Update 2021: These are the implications

On November 17, 2021, Google rolled out a major core update. We’ll show you the first effects of the algorithm innovations.

A good four months after the major double core update, Google has now rolled out the next far-reaching algorithm changes. Before the launch, several posts from SEOs and a tweet from Google’s head of the SearchLiaison, Danny Sullivan, indicated an imminent innovation.

On November 17th, the time had come and many SEO managers expected devastating effects on their own page performance. One Analysis of SemRush now shows what effects Google’s update actually had.

Google’s November Core Update: Higher volatility than the July Core Update

SemRush’s insights show that the November Core Update resulted in higher overall volatility than four months ago. The desktop SERPs showed twelve percent more volatility and the mobile SERPs were 23 percent more volatile after the November update.

Furthermore, 16 of the 17 analyzed verticals showed a higher volatility during the update in November than in July. Overall, the average volatility of all industries in November is 20 percent higher than in July.

Ranking changes after the November Core Update are two percent higher

The core update in July affected the top 10 SERPs to such an extent that only five percent of them fell short of their previous position in the Google ranking. With the current update, the effects have increased significantly to seven percent. The SemRush analysis states:

However, we see a different picture when we look at the top 5 results:
During the July 2021 Core Update 7.4% of URLs ranking in the top 5 previously ranked beyond position 20;
During the November 2021 Core Update only 4.4% of URLs ranking in the top 5 previously ranked beyond position 20.

Top 100 Websites: Who Made the Biggest Profits and Losses?

SemRush also looked at which sites had the biggest profits and losses. The company summarizes the results as follows:

The November 2021 core update winners gained around 33 positions, with an average position of 10.

The losses look slightly more moderate. On average, those hit the hardest by the update lost around 28 positions. Just as during the July 2021 update, the average page that was within the top 100 most negatively affected list ranked at position 16.
