A prospective client asks ChatGPT, “Which agency should I hire to manage our social media?” The answer names four companies. Yours isn’t one of them, and you never saw it happen.
This is the gap that AI share of voice measures. It shows how often AI assistants mention your brand compared with your competitors when people ask questions in your category.
In this guide, you’ll learn what AI share of voice is, how to measure it in six steps, which metrics matter, and how to improve your score.
What Is AI Share of Voice?
AI share of voice is your brand’s share of all brand mentions across a fixed set of AI-generated answers. If you and three competitors are mentioned 40 times in total, and 14 of those mentions are yours, your AI share of voice is 35%.
Think of it as the AI-era version of market share in search. Traditional SEO asks, “Where do we rank?” AI share of voice asks, “Are we part of the answer at all?”
It covers answers from tools such as ChatGPT, Perplexity, Gemini, Microsoft Copilot, Claude, and Google’s AI Overviews. Teams also call this practice AI visibility, AI search visibility, or LLM brand tracking. The idea is the same: count brand mentions in AI answers, then compare them with your rivals.
AI Share of Voice vs. Traditional Share of Voice
Because AI answers change from run to run, you measure AI share of voice as a trend across many prompts, not as a single snapshot.
Why AI Share of Voice Matters for Your Brand
AI assistants compress research into a short list. Buyers still compare and double-check, but the shortlist often starts with an AI answer. If you’re missing from it, you may never make the first round.
- Shortlists form earlier. People ask for recommendations before they visit any website.
- Clicks are not the only goal. An answer can name a brand without sending a visit, so traffic reports alone hide the loss.
- Competitors can pull ahead quietly. A rival may be named more often without ever outranking you on Google.
- It guides content and PR. Seeing which sources AI relies on shows where to earn mentions.
- It gives stakeholders a clear number. Agencies and in-house teams can report a comparable score over time.
This is where generative engine optimization (GEO) and answer engine optimization (AEO) come in. They are the practices for improving how AI systems find, understand, and cite your content. AI share of voice is how you measure whether they work. For a deeper comparison, read our guide to SEO vs. GEO vs. AEO. Google also explains how its AI features use web content in its Search Central documentation.
How to Measure AI Share of Voice in 6 Steps
You don’t need a complex setup to start. You need a consistent method.
- Define your competitor set. List 4 to 8 brands that buyers compare you with. Include direct rivals and one or two category leaders. Keep the same list every time.
- Build a prompt library. Write 30 to 50 questions real customers ask. Group them by stage: discovery (“best social media management tools for agencies”), comparison (“Tool A vs. Tool B”), and decision (“is Tool A worth it for a university”). Our guide to AI prompt research shows how to find them.
- Pick your platforms. Start with the tools your audience uses most, usually ChatGPT, Gemini, Perplexity, and Google AI Overviews. Add Copilot or Claude if your audience uses them.
- Run every prompt the same way. Use identical wording, and run each prompt more than once, because answers vary. Record the date, the platform, and whether web search was on.
- Log what each answer says. Note which brands were named, in what order, with what sentiment, and which sources were cited.
- Calculate and repeat. Divide your mentions by total mentions, then track the result every month.
The formula is simple:
AI share of voice (%) = your brand mentions ÷ total mentions of all tracked brands × 100
A Worked Example
The numbers below are illustrative only. Imagine you run 40 prompts and count one mention per brand per answer.
Your brand holds 35% of the conversation. Next quarter, you re-run the same prompts and compare. If you move to 42%, you can connect the gain to what you changed, such as new content or new third-party mentions.
You can also weight mentions by position, so a brand named first counts more than one named fifth. Keep the weighting simple and document it so results stay comparable.
Which Metrics to Track Beyond Mentions
Mention counts tell you how often you appear. These metrics tell you how well.
Start with mention rate and AI share of voice. Add the others once your process runs smoothly.
Competitor Analysis in AI Search: Reading the Gaps
The score is only the start. The useful part is understanding why a competitor wins. For each prompt where a rival is named and you are not, ask:
- Which sources does the AI cite when it names them: review sites, news, directories, or their own blog?
- How does the AI describe them compared with you?
- Do they win on every platform, or only on one?
Suppose a rival keeps appearing because a trusted industry roundup lists them. Your gap is a source gap. The fix is earning a place in that source, not rewriting your homepage.
Brand Visibility in ChatGPT vs. Other Platforms
Each platform draws on different sources, so your results will differ. You might do well in Perplexity, which shows its citations openly, and poorly in ChatGPT. Track platforms separately before you average them.

How to Improve Your AI Share of Voice
No one can guarantee a recommendation from an AI system. These actions consistently support AI visibility:
- State what you do, clearly. Describe your products, audience, and use cases in plain language so AI systems can summarize you accurately.
- Write answer-first content. Answer real customer questions in the first few lines, then add detail. FAQ sections work well. Google’s people-first content guidance is a good checklist, and the company says it judges quality, not how content is produced.
- Earn mentions on trusted third-party sites. Industry roundups, review platforms, news coverage, and partner sites often feed AI answers.
- Keep reviews and profiles current. Complete profiles and recent reviews support accuracy. If you run multiple locations, see our local SEO for AI search playbook and how Eclincher helps franchises and multi-location businesses.
- Stay active on social media. Public posts, replies, and community conversations create more places where your brand is discussed. Our guide to social listening strategies shows how to track them.
- Use structured data. Mark up your organization, products, and FAQs with schema.org vocabulary so machines can read them.
- Fix wrong information at the source. If an AI answer repeats something outdated, correct the page it relies on.
After each change, wait for the next measurement cycle before judging the result.
Common Measurement Mistakes
- Running prompts once. AI answers vary, so a single run can mislead you.
- Testing only branded prompts. If you ask about your own brand, you will always appear. Test category questions too.
- Changing the prompt set every time. You can’t compare trends if the questions keep changing.
- Ignoring sentiment. A mention that calls your brand expensive or outdated is not a win.
- Tracking one platform only. Your audience may use several tools.
- Never updating the competitor list. Review it every quarter, because rivals change.
Who Should Track AI Share of Voice?
- Marketing agencies: Add AI share of voice to client reports and benchmark each client against its rivals.
- Social media managers: Connect campaigns and community engagement to changes in how AI describes the brand.
- Universities: Test prompts such as “best universities for nursing” or “online MBA programs” to see how your programs appear to prospective students.
- Other industries: Any brand that buyers research before purchasing, including SaaS, healthcare, retail, and finance, can use the same method.
