| File | Content |
|---|---|
| `grovia-ai-visibility-baseline_2026-09-10_prompts.csv` | prompt ID, language, category, exact wording |
| `grovia-ai-visibility-baseline_2026-09-10_measurements.csv` | one row per measurement: date, time (CEST, where recorded), platform, model, run, location/VPN, providers and tools named, whether sources were captured |
| `grovia-ai-visibility-baseline_2026-09-10_sources.csv` | one row per cited source: measurement ID, domain, URL, source type, position |
| `grovia-ai-visibility-baseline_2026-09-10_providers.csv` | providers in **alphabetical order** with the number of measurements naming them |

## Counting rules

- A provider counts **once per answer**.
- Spelling variants of the same provider are merged; names of individual persons are replaced by "Individual consultant (name removed)".
- **Mention frequency is not a statement about quality.**
- Gemini shows sources as display names without URL; read domain frequencies per platform.
