## Definition

SERP volatility is the degree of fluctuation in search engine results page rankings over time — used as an indicator of algorithm updates, competitive shifts, or content quality changes. High volatility periods often correlate with Google algorithm updates.

## Why It Matters for AI Search

SERP volatility matters for AI SEO because Google's algorithm updates affect [AI Overview](https://www.platelunchcollective.com/services/answer-engine-optimization) citations, though recent data indicates a decreasing correlation between AI Overview citations and traditional top rankings. When SERP volatility spikes, brands should monitor their AI Overview citation presence alongside traditional rank tracking. Updates affecting featured snippet eligibility may not always simultaneously affect AI Overview citations — AI Overviews synthesize from multiple sources, distinct from the single-source nature of featured snippets — though both surfaces favor strong content quality signals.
