Freeze the conditions
Name the exact product, mode, model label, plan, account state, country, locale, date, prompt, and run. Keep branded and unbranded jobs separate and preserve a development panel apart from a locked holdout.
Phase One insight
Measure generative visibility as a controlled product study.
One prompt, one screenshot, or one vendor score is not a visibility baseline.

Preserve the evidence
Store the complete response, exposed source panel, citation order, timestamp, and product conditions. Rate entity appearance, claim accuracy, citation support, and recommendation qualification independently.
Report n/N and limits
A mention is not automatically a recommendation, and a citation does not prove it caused the answer. Report platform-specific rates with numerators, denominators, invalid-run handling, and the exact observation window.
Current first-party crawler guidance
As reviewed on 2026-08-06, ChatGPT Search, Claude search, Perplexity search, and Gemini-related systems expose different crawler roles and controls. Search or retrieval access is separate from model-training access, and allowing a crawler does not guarantee retrieval, citation, mention, or recommendation.
