Do you want to keep your eyes on Google search volatility? But don’t know how?

This post is made for you because I am going to introduce you to a tool that can help you to keep your eyes on Google search ranking volatility and detect the Google search algorithm update.

Semrush is a bundle of SEO tools that provides more than 40 SEO tools to perform various SEO tasks such as keyword research, site audit, backlink audit, competitor analysis and many more.

Along with tools for all these tasks, Semrush does have a tool that can help you to keep your eyes on Google search volatility.

That’s named “Semrush Sensor“. In this post, I will be sharing everything that you need to know about this tool. Also, how can you detect Google updates?

What Is The Semrush Sensor?

It is an SEO tool created by Semrush to measure the volatility in Google’s search algorithm.

The tool has been designed to monitor the volatility in the Google search algorithm and warn you when there is any possible algorithm update. It tracks the volatility and gives a score out of 10, the high Sensor score means it is possible any search algorithm update is undergoing.

This tool can help you with:

  • Check your websites’ rankings volatility compared to your competitors
  • Get notified about the Google algorithm update through emails or browser push notification

Let me give a quick overview of the Sensor tool by Semrush:

Databases Available

Sensor databases

There are six databases available with the Sensor tool:

  • United States
  • United Kingdom
  • Spain
  • Germany
  • France
  • Australia

Semrush provides a separate Sensor score from all available databases. Also, for desktop and mobile search results. It makes it easy to find which kind of search results got affected due to the Google algorithm update.

SERP Volatility

SERP volatility score is given out of 10, the higher score means more volatility in the search results. If the score is low than 5, it shows that the volatility is normal as usual days.

If it goes higher than 5 out of 10, then it shows that Google’s algorithm has undergone significant changes.

Google Algorithm Updates usually do not impact all the industries(niches), devices and countries. It only affects some pieces of search results.

Semrush makes it handy for you to find which area got impacted due to the algorithm update. Because you can track any specific category(niche) to find out how hard it got affected.

Sensor categories

Along with this, you can find scores for any specific devices(desktop and mobile) and country. Also, you can find out which SERP features got affected most by the recent Google update.

Personal Score

If you want to find your websites’ ranking volatility, this can help you in doing so… It is not available for free to use, rather you require to get any of the Semrush premium plans.

You can track your websites’ ranking fluctuations for the keywords your website is ranking for. You can get started with the Semrush pro by claiming its 14-days free trial and adding up your product for position tracking with your keywords.

Winners And Losers

In this tab, you can find all the domains which got most affected on a given day. Winners are the domains that climb up in rankings and Losers are which got dropped in rankings on the same day.

How Sensor Score Is Calculated?

Here is what the Semrush team says…

“For each keyword, we do a per-item comparison of “today’s” results vs “yesterday’s” results. We measure how much has changed in a day using Levenshtein distance (as a basis) and normalization. The total value of the score reflects the total search volatility for the day.”

Semrush creates a list of keywords from multiple industries and monitors them at the beginning and at the end of the day to detect the volatility in search rankings.


How To Use Semrush Sensor To Detect Google Update?

It updates the volatility score every single day from the results they got from measuring volatility in rankings for their set of keywords. The score is given out of 10, if the score is high from 5 that means there is high volatility in the Google search algorithm. And under the 5 shows normal volatility.

Note: Sensor score is currently 9.2/10 which is very high, it is because Google Product Reviews update that Google has recently rolled out.

You can also find the volatility score for the last 30 days in the form of a graph. You can see in the below image, I have marked the score 9.3(very high) on Nov 18, 2021. Sensor detected the high score and there was a Google algorithm update.

Also, Semrush shares any known information about the changes in the algorithm they detect. You can find that section at the bottom of the report page.

Semrush allows you to find a separate volatility score for any category, device and country. It is a very important feature to find out which pieces of Google’s algorithm got affected due to the new Google algorithm update. Because Google algorithm updates do not impact the entire search data, sometimes a certain category gets affected and sometimes a certain device.

So, this feature makes it easy to find which category, device or country specifically got affected by Google’s algorithm update.

Along with all these data, you can find the day-to-day volatility on specific Google search engine results features. This section can give a clear view of which type of SERP features got affected(if any).

How To Get Notifications About The Volatility?

Let me show you how you can subscribe for notifications:

Just go to Semrush Sensor and you can find the Subscribe to notifications button at the top-right corner.

When you click on that, you will be asked to choose how you want to receive notifications. There are two ways available, Email notifications and Browser push notifications.

I recommend choosing the email notification, just choose that and enter your email address to receive notifications about the Google search volatility. At last, hit the Subscribe button.

You will receive a confirmation email. Just click on the link available in the email to confirm your subscription.

Once you have subscribed to notifications, you will receive email notifications from the Semrush when the Sensor score jump to “high” or “very high” from a lower zone.
