SERP Volatility
01 Definition
SERP Volatility meaning: The degree to which search rankings shift over a short period.
SERP volatility measures how much search result rankings move over a short time, often day to day. High volatility can signal a Google algorithm update or unstable results for a topic. Third-party trackers estimate it with tools sometimes called weather reports; these scores are not official Google data.

Why it matters
How SERP Volatility fits the work
Watching volatility helps SEOs tell normal fluctuation from a possible algorithm update and decide whether ranking drops need action.
In context
A tracking tool flagged high SERP volatility for three days, hinting that Google was rolling out a broad ranking change.
Practical note
Volatility trackers are third-party estimates, not Google metrics, so confirm changes with your own analytics before reacting.
