The practice behind AIV Index — and why you can check our working.

AIV Index — short for AI Visibility Index — is a subscription product from Auto Alpha Advisory (Pty) Ltd (registration number 2025/213512/07), a South African company based in Cape Town.

The practice behind it

Auto Alpha Advisory ships full website and GEO (generative-engine optimisation) audits to its retainer clients. AIV Index is the productised, ongoing-measurement layer of that same practice — the instrument the audit work already relies on, sold as a subscription. The practice is founded and run by Matt Owen, CA(SA).

AAA’s audit engine already checks whether AI crawlers can read a site, and whether its pages carry the statistics, quotations and cited sources that make them quotable. AIV adds the monthly sweep across ChatGPT, Claude, Perplexity and Gemini, so a one-off audit becomes a running measurement.

Why you can trust the numbers

We believe a transparent measurement tool is more defensible than a black-box dashboard. So:

• The methodology is published. It is grounded in the Princeton GEO study (KDD 2024) and the Vercel/MERJ AI-crawler study (December 2024), and the full measurement approach is documented on our methodology page.
• The data is yours. Every raw response and source is readable in full on your dashboard, and you can take it to another consultant who is not us. We do not hold your measurement history hostage.
• The noise is handled honestly. Each prompt runs three times per engine, five on Scale and on your highest-priority prompts, with live web search; we report the aggregate, not a single response, and drift alerts fire only when your share moves by 10 percentage points or more between runs.
