## What it checks

- Indexability and canonical URL
- AI crawler access in robots.txt
- Title, description, and primary heading
- Relevant JSON-LD structured data
- Question-oriented page content
- XML sitemap discovery
- Optional llms.txt discovery

The result is a readiness score, not a measurement of current ChatGPT, Claude, Gemini, or Grok recommendations.

## Measure actual visibility

To measure actual visibility, freeze neutral buyer questions, run the same set across the providers your buyers use, and preserve answer and citation evidence. The paid benchmark sends 25 frozen questions to four providers for 100 planned answers.

## Important limitation

AI answers vary by provider, model, search source, locale, and time. No technical or content tactic guarantees a recommendation, citation, or ranking.
