The ARO Index measures which local businesses AI actually recommends. Not who gets mentioned, who gets chosen. We run live audits across ChatGPT, Claude, Gemini, and Perplexity, then publish the rankings by city and category.
The models change fast, so the method does too. What started as a single question per platform is now a multi-query read built to catch how AI really interprets a business. The research is dated, public, and always moving.
See how the index is evolvingMeasures how well a single website is structured to be recommended by AI. Entity clarity, schema markup, topical authority. A diagnostic score.
Measures a business competitively within its category. Weighted by recommendation rate, model agreement, and audit recency.
How many AI platforms recommended this business for the tested query. Agreement across more platforms means a stronger, more reliable ranking.
AI models update regularly. A business that was not being recommended six months ago can rank highly today after optimizing for AI recommendation signals.
ARO Index started with a pattern I kept seeing: businesses pouring money into SEO while AI platforms recommended their competitors instead. Traditional reporting couldn't explain it. So I built something that measures what AI actually recommends, and tested it on my own site first. ARO Index is that measurement, made public.
