Semrush Sensor
Semrush Sensor measures volatility in search results, tracking down 20+ categories on mobile and desktop and highlighting possible Google Updates.
The Sensor measures SERP volatility on a scale of 0-10 to indicate how much overall change is happening daily. If there’s a high score, it means that rankings are fluctuating, and you could lose or gain positions. If there’s a low score, your website rankings are more likely to remain stable.
