AI Search Visibility: The Only 3 Metrics That Matter

How do you measure AI search visibility?

Measure AI search visibility with three metrics tracked weekly across a fixed portfolio of buyer-intent prompts: (1) mention rate — how often your brand is named in the answer; (2) positioning — is the mention positive, accurate and prominent; (3) competitor share-of-voice — which competitors share the answer with you. Track these across ChatGPT, Gemini, Claude, Perplexity and Copilot.

Why Traditional Rank Tracking Misses

There is no 'position 1' inside a ChatGPT answer. There is no SERP to scrape. Traditional rank trackers tell you nothing about whether you are part of the conversation when buyers ask AI assistants for recommendations. You need a different instrument.

Building Your Prompt Portfolio

Pick 20-50 prompts your real buyers ask — discovery questions, comparison questions, recommendation questions. Run them weekly across the five major assistants. Log the answer, screenshot it, score each metric. This becomes your baseline.

What Good Looks Like

A mature AI SEO program shows: mention rate climbing from 0-10% at month 1 to 40-70% at month 6 on target prompts; positioning shifting from 'mentioned in passing' to 'recommended first'; and competitor share-of-voice falling as you become the consensus answer.
