Question 1

What is the mapou Visibility Index?

Accepted Answer

The mapou Visibility Index (MVI) is a monthly 0-100 score measuring how often AI assistants cite a brand in buyer-intent prompts. Each brand is tested with 20 fixed prompts across five AI engines, ChatGPT, Perplexity, Gemini, Claude, and Grok, for 100 atomic verdicts per brand. The score is phase-weighted across Discovery, Filtered Discovery, Comparison, and Evaluation buyer-intent phases, with Wilson 95% confidence intervals.

Question 2

Which AI assistants does the mapou Visibility Index test?

Accepted Answer

MVI tests every brand against ChatGPT (gpt-4o-mini), Perplexity (sonar, web-grounded), Google Gemini (gemini-2.5-flash), Anthropic Claude (claude-haiku-4-5), and xAI Grok (grok-3-mini). All five engines run in parallel. Engines are weighted equally, no market-share gymnastics.

Question 3

How often is the mapou Visibility Index updated?

Accepted Answer

Every month. The same 20 buyer-intent prompts are reused each month so scores are directly comparable over time. Methodology version is locked at v1.0, any change to phase weights, prompt templates, or engine list bumps the version and is disclosed publicly.

Question 4

How does mapou compete with ChatGPT visibility tools like Profound or Otterly?

Accepted Answer

Most AI visibility tools test a single AI engine, use rotating prompts, and report engagement metrics. MVI tests five engines, uses a fixed pre-registered prompt set per segment, reports citation rate (not engagement), and discloses confidence intervals. It is the only multi-engine, phase-weighted, replicable visibility benchmark in AI search.
