So, twice a day (at the beginning and end of the day), SEMrush uses its bot to crawl the web and records organic search results for millions of keywords they track. Then a comparison is conducted against the previous day’s results. The value gotten provides the search volatility for that specific day.
For example, a high score like 9 indicates multiple position changes in the SERPS. This is usually a result of a significant Google algorithm update or some kind of widespread penalties affecting a huge number of websites.
You should note that the sensor score is not a guarantee that your search engine ranking position will change. But rather the possibility that you might experience changes in your rankings.
How Does the SEMrush Sensor Detect Changes in Google’s Search Algorithm?
SEMrush ranks search volatility on a scale of 0 – 10. The higher the score, the more volatile the SERP changes.
Here is a breakdown of the volatility score:
0 – 2: Low volatility;
2 – 5: Normal volatility;
5 and above: High Volatility.;
8 and above: Very high volatility.
Scores from 5 and above indicate that there is an algorithm update. Google algorithm updates can be a change in a specific area or the whole algorithm (Google core updates) which usually impacts all Google search results, and for every language.
The SEMrush Sensor is updated every day and every time it detects changes, it shares a report. The reports include data for the past 30 days.
You can filter and compare scores in 25 categories. The categories include;
Autos and Vehicles;
Beauty and Fitness;
Arts and Entertainment;
Books and Literature;
Computers and Electronics;
Food and Drink;
Home and Garden;
Business and Industrial;
Hobbies and Leisure;
Internet and Telecom;
Jobs and Education;
Law and Government;
People and Society;
Pets and Animals;
To identify more specific algorithm updates, filtering results according to categories, location and even devices can help.
Yes. Just like how results may differ in different categories, data in specific countries do too. So high volatility in the US does not always correlate to high volatility in Australia.
