The updates to the Google search algorithm are extra excessive this yr

Semrush’s Mordy Oberstein put out some data that proves I’m not insane or insane, at least when it comes to my reports on them Updates to the Google search ranking algorithm. Yes, I’ve reported more of these updates this year than in previous years, but for good reason the search results are more volatile this year than in previous years.

How much do Google search results fluctuate this year compared to previous years? Well, according to Semrush data, desktop results are 68% more volatile and mobile results 84% ​​more volatile than last year. That’s a lot, a lot.

Mordy has published many charts and data too Twitter from the Semrush dataset to view it.

Desktop 2020 vs. 2021:

Mobile 2020 vs. 2021:

I’m going to embed Mordy’s tweets because he did all the work proving I wasn’t my rocker …

That is, on the desktop, from January ’21 to October ’21, we see a 68% increase in the number of days of high volatility

(For your information: high volatility = 5/10 – 8/10 on the Semrush sensor https://t.co/3Eztsk8EWW) pic.twitter.com/IHglUd4i8Z

But what about the cell phone?

If you just look at “high” volatility levels (again high at 5/10 – 8/10 on the sensor) … we are already volatile at around 50% by 2021! pic.twitter.com/88SykCllTL

What if we throw VERY HIGH volatility into the mix on the phone?

Slightly higher than the percentage we see on desktops, with nearly 57% of 2021 so far “volatile”.

That’s about 7 percentage points of only VERY high volatility on mobile devices in 2021. pic.twitter.com/vPmLtkk8J3

That’s a lot fewer days of low / normal volatility on the desktop and a lot more days of increased volatility on the desktop!

That said, some niches might have many “low volatility” days while others might have many more “high volatility” days —- the data in the charts above is the average of those industries.

In 2021 this number will drop to just 3!

Only 3 niches showed more than 10 days of low volatility in more than 6 months in 2021!

Ouch! pic.twitter.com/PmnDNJcAUC

And this number has been reduced to only 3 niche industries in comparison to the same period in 2021. pic.twitter.com/38AEnbZ4EB

Finally:

In short, Barry is not crazy … there is a ton more rank volatility on both the desktop and mobile SERPs these days!

Anyway, it’s nice to have data to back up all of these stories. Thanks Mordy, even if I didn’t ask for the backup – good to have it.
