Share of AI
A brand's portion of relevant AI answers or recommendations within a tracked market.
What is Share of AI?
Share of AI compares a brand's presence with the competitive set across a defined prompt library. The calculation should state what counts as a mention, recommendation, or ranked position. It is most useful as a trend and competitor benchmark, not as an isolated universal number.
Across 200 tracked answers, Brand A appears in 58 while all monitored brands receive 310 total qualified mentions.
Why it matters for AI visibility
AI answers can shape awareness and buying decisions before a person visits a website. Understanding share of ai helps teams connect what a model says with the prompts, sources, and technical signals that influenced the result. The useful next step is to observe the evidence, compare it over time, and act on the specific gap.
How to measure or use it
- Define the scope. Choose the relevant market, prompts, models, locations, and time window.
- Keep the evidence. Save the complete answer, its citations, and the page or claim being evaluated.
- Compare patterns. Look for repeated movement across prompts and models instead of reacting to one response.
- Take a specific action. Improve the owned page, correct a claim, earn third-party inclusion, or create better evidence.
