Google caches AI Overviews for high-volume queries instead of regenerating each time

SEO practitioner gaganghotra observed a notable Google behavior change:
- For high-volume queries (e.g. "black friday 2026" searched from Melbourne), Google caches AI Overviews rather than regenerating each time
- The same answer persists identically for both logged-in and logged-out experiences over an extended period
- Screenshots show matching output across sessions
Implication for sites relying on AI Overviews visibility: once cached, the output stays frozen, making real-time optimization ineffective.
