What is AI Visibility Score?
A composite metric summarizing brand presence across AI assistants — mention rate, citation rate, position, and sentiment in one trackable number.
Definition
An AI visibility score is a composite metric condensing brand presence in AI answers into one trackable number — typically combining mention rate (how often you appear for tracked prompts), citation rate, average position among named brands, and sentiment, across assistants and time.
It's the AI-era analog of an SEO visibility index, built on prompt-tracking samples rather than rank positions.
Why it matters
Executives need one number with a trendline; practitioners need the decomposition. A good score supplies both: the headline tracks program health, while its components diagnose cause — mentions down because ChatGPT changed sources? Citations up after the data-study launch? Because LLM answers vary run to run, scores built on repeated sampling are meaningful where single-query spot-checks are noise. Treat any tool's absolute score as its own scale; the trend and competitor gap are the signal.
Frequently asked
What makes a visibility score trustworthy?
Transparent methodology: which prompts, which assistants, how many samples, how components weigh. Distrust scores that won't show their inputs — variance across LLM runs makes undisclosed methodology unfalsifiable.
How often should the score update?
Weekly sampling is a practical floor for trend detection; daily for competitive categories. What matters is consistency — same prompts, same method — so movement reflects the market, not the measurement.
