What Is the Semrush Sensor?
Semrush Sensor is a tool that measures Google's search algorithm's volatility using the daily rankings of millions of keywords. Want to stay updated on major Google Algorithm changes? Unlock the complete marketing potential of your website with the Semrush Sensor as it provides the Sensor Score that enables the detection of search changes impacting your website's traffic. So, Semrush Sensor reveals whether your actions have positively impacted your website or Google's algorithm changes have sent things in the right direction.
How Does the Semrush Sensor Detects Changes in Google's Search Algorithm?
Semrush publishes a volatility score on a scale of 0 to 10 each day. A higher score translates to greater volatility in Google's SERP.
But what do different scores represent?
- A score of 0 - 2: Low volatility
- A score of 2-5: Normal
- A score of 5 and above: High volatility, i.e., it suggests an update in Google's search algorithm.
- A score of 8 and above: Very high volatility
Google makes changes to:
- Specific algorithm pieces or
- The general algorithm that impacts all search results
Whenever the Semrush Sensor detects a change, it shares the information about the algorithm change in the form of a report. The Sensor is updated each day, and it displays data for the past 30-days.

Do Semrush Sensor Databases Differ for Different Countries?
Like categories, different countries have different Sensor Scores that fluctuate each day. So, a day of high volatility in Germany's database doesn't necessarily correlate to a day of high fluctuations in the US database.
Semrush Sensor pulls data from various countries, including
- United Kingdom
- United States
- Spain
- Germany
- Italy
- France
- Japan
- Australia
- China
How Is the Semrush Sensor Score Calculated?
Semrush records organic search results for certain keywords twice daily– at the beginning and end of the day. For every keyword, it conducts a per-item comparison of that day's and the previous day's results. It accounts for the change per day employing Levenshtein distance and normalization. The total value obtained provides insight into the total search volatility for that day.
For instance, if the score is as high as 9, it reflects that several position changes have happened in the Google SERPs. It is an indication that either there is an algorithm update or there are penalties put for offending websites.
However, it is not guaranteed that the position of your site will change by a change in volatility, but there are chances that you might see a change in the ranking of your website in Google's search engine.
How Can I Use The Sensor To Detect Changes For My Website?
Semrush Sensor has a Personal Score tab. So, if you have a Semrush account, you check the score that reflects changes to your linked website. Those who do not have a Semrush account will have to sign up for a free trial, enter their domain and click on the "Try it" button to see the Semrush Sensor score for their website.
The score and the report display daily volatility specifically for your website on the basis of keywords you provide to Semrush in the "Position Tracking" section. So, if you add more keywords to the system, you have a more accurate score.
Semrush also allows you to get Sensor notifications without visiting the website. Clicking on the "Subscribe to Notifications" button displayed at the top corner of the dashboard signs you up for the alerts.
