Limitations
- Single pass. Run-to-run variance is not characterised.
- 18 queries returned no Google AI Overview panel. Excluded from that engine's denominator rather than counted as absences.
- Gemini's cited sources are largely unavailable through Google's API, so source analysis rests on the other engines.
