AI Share of Voice: How Often Does AI Name You, Not Them?
AI Share of Voice is the percentage of AI-generated answers that mention your brand instead of a competitor, across ChatGPT, Perplexity, Gemini and Claude.
Google AI Overviews reached 2 billion monthly users by July 2025, and Perplexity handled 780 million queries in May 2025 alone. Every one of those answers names someone. This guide shows how to find out whether it's you.
Check Your PageWhat Is AI Share of Voice?
AI Share of Voice is the percentage of AI-generated answers, across a set of buyer questions, in which your brand appears instead of a competitor. Ask ChatGPT, Perplexity, Gemini and Claude the same 15-20 questions your customers ask, count how many answers name you, and you have a rough number. Ask the same questions about a competitor and you can compare.
It is the AI-era version of a metric marketers already know. In classic search, share of voice meant how often you ranked, or how much of the visible results page your listings occupied, compared to competitors for the same keyword set. AI search collapses that ranked list into a single written answer, so the metric collapses with it: instead of counting positions, you count mentions inside the answer itself.
The number can move for reasons a ranking check would never show. An AI engine can name three competitors and leave you out entirely, even if your page ranks first in Google for the same query, because the model chooses its own sources when it writes the answer. Share of voice is the only way to see that gap.
How to Estimate Your AI Share of Voice
Build a Real Question Set
Start from the questions your customers actually type or ask out loud, not a list of your own keywords. Ten to twenty questions per topic is usually enough to see a pattern without spending all day on it.
Ask Across Engines, Not One
ChatGPT, Perplexity, Gemini and Claude each choose their own sources. A brand that appears in three of the four answers has a very different share of voice than one that appears in only one.
Count Competitors, Not Just Yourself
Your share of voice only means something next to a baseline. Run the same questions for two or three named competitors and see who the AI actually recommends.
Why AI Share of Voice Matters Now
A Channel Your Analytics Miss
An AI answer can recommend you without a single click landing in your analytics. Share of voice is the only way to see a recommendation that never shows up as traffic.
Most Brands Have Not Measured It Yet
Across the 47,000+ pages GEO-Score has analysed, the average GEO score is 50.5 out of 100. Almost nobody has done the work of tracking, let alone improving, their AI share of voice, so a small effort stands out.
It Reveals Your Real Competitor Set
AI answers do not always name the competitors you'd expect. Tracking share of voice across a real question set often surfaces a smaller brand you'd never have flagged as competition.

AI Share of Voice FAQ
What is AI Share of Voice?
AI Share of Voice is the percentage of AI-generated answers, across a set of buyer questions, in which your brand is named instead of a competitor. It's measured per engine and per question set, not as one single universal number.
How do I measure my AI Share of Voice?
Pick 15-20 real buyer questions, run them through ChatGPT, Perplexity, Gemini and Claude, and record whether your brand is named in each answer. Do the same for two or three competitors so the number has a baseline to compare against.
Which AI engines should I check?
Start with ChatGPT, Perplexity, Google Gemini and Claude. Together they cover most AI answers people see today. Add Google AI Overviews if you can, since it reached 2 billion monthly users by July 2025.
How often should I recheck it?
AI answers are not fixed the way a Google ranking is; the same question can return a different answer on a different day. Recheck monthly rather than daily, and treat a single result as one data point, not a verdict.
How do I improve my AI Share of Voice?
Start with access: AI crawlers need to be able to read your page. Then make your answer easy to lift: a direct answer in the first paragraph, real statistics with a named source, clear headings. GEO-Score's page analysis scores this across 22 metrics and lists what to fix first.
How is this different from traditional share of voice?
Traditional share of voice counts ranking positions or impression share on a results page. AI Share of Voice counts mentions inside a single written answer instead, because that is what a generative engine produces instead of a ranked list.
