SEMRush Sensor is a search engine analysis tool created by SEMRush that helps one keep informed on the fluctuations of Google’s search Algorithms. This tool tracks and analyses the changes in SERP or Search Engine Page Result ranks and try to detect any changes in Google’s algorithm (as well as Baidu in China). A sensor score out of 10 is then assigned to gauge the volatility.

Some of the uses of SEMRush Sensor are as below.
1. Detect or track Google Search Engine Algorithm updates
Not all Google’s updates are announced on the Google’s Webmaster blog. With the help of SEMRush Sensor, one can monitor these changes and learn of potential SEO strategies that can be deployed to improve one’s ranking.
For example, below is the chart for volatility for the last 30 days.
The Google symbol at the bottom of the chart refers to high volatility where the monthly Google Update took place.
2. Monitor changes and occurrences of specific SERP features

These include the likes of:
- Featured Snippets
- Local Pack
- Shopping Results
- Knowledge panel
- Top Stories
- Instant Answers
- Top Ads
- AMP Usage
- HTTPS Usage
For example, in the below result from SEMRush Sensor, the percentage of the SERPs where the features appear in the top 20 results. We see that the Knowledge Panel feature powered by Google’s database that gathers information from a variety of trustworthy sources forms 28.75% of the results on the day this screenshot was analyzed. Also, about 13.99% of the results in the top 20 seem to be AMP based.
3. Monitor deviations for categories from average monthly volatility
With the help of the SEMRush sensor’s Deviation tool, one can measure the difference between the volatility for a certain day to the average monthly volatility.
This measurement lets us understand which search categories are unstable for the given day.
The deviation of a certain category can be classified as Normal deviation, Moderate deviation, or Critical deviation with respect to the average monthly.
For example, In the below screenshot, we see that the Real Estate category had a normal deviation with respect to the average monthly deviation. Similar was the case with Food & Drink, Books & Literature category, etc.
4. Monitor Winners and Losers
SEMRush Sensor also monitors the average moment of tracked URLs in the top 20 search results. Based on these fluctuations in positions, and the limited set of keywords tracked by Sensor the top winners and losers are surfaced by the SEMRush sensor.
This type of data can be used to analyze the types of domains that gained or suffered the most losses due to updates.
For example, in the below chart below are the top 5 domains winners for the day this was grabbed in the Sports category.
