GLOSSARY TERM
What is SERP Volatility?
Definition
A measure of how much search results are shifting day-to-day, typically tracked by tools like Semrush Sensor, Mozcast, or Algoroo. Spikes indicate algorithm updates.
Why it Matters for AI Search
High SERP volatility on a day your traffic dropped means an algorithm update, not your fault directly. Low volatility on a drop day points at a site-specific issue. SERP volatility tools are the cheapest early-warning system you can have.
