AI share of voice is your share of all the times AI answers name you or a competitor you track: count how often the answers name your brand, divide by how often they name every tracked brand, yours included, and you have it. Curve Compliance's AI Visibility shows it for the questions your patients actually ask, across ChatGPT, Google AI Overviews, Google AI Mode, Perplexity, Claude and Gemini, next to the visits and bookings those answers bring you. AI Visibility is a feature in Curve Compliance, and Curve also offers it as a managed service.
Want to see your share of voice on your own patients' questions, next to the bookings AI visits lead to? Curve's team sets up your questions, competitors and topics. Book a call to see AI Visibility on your own questions, or to talk about the managed service.
How AI share of voice is calculated
The formula is simple. Take a fixed set of questions and a fixed list of brands. Ask each question of each assistant and count how many times the answers name each brand. Your share of voice is your count divided by the total for all the brands on the list. A made-up example with round numbers: if the answers name your practice 20 times and your tracked competitors 60 times, you hold 20 of 80 mentions, a quarter of the conversation.
Two choices change the number, so check them before you compare figures from different tools. The first is which brands are on the list, because adding a competitor adds to the total. The second is what counts: mentions only, or mentions and citations. Here is how two vendors describe their own versions:
| Tool | How it defines AI share of voice, in its own words | Source |
|---|---|---|
| Ahrefs Brand Radar | “the percentage of AI responses within your topic set that mention or cite your brand versus competitors” | Ahrefs |
| Scrunch | “Scrunch measures AI share of voice by tracking a brand or competitor's mentions or citations as a share of the same metric across the tracked competitive set.” | Scrunch FAQ |
Curve's AI Visibility reports three numbers about the answers: mention rate (how often AI answers name you), citation rate (how often they cite your site) and share of voice (your share of the mentions among the brands you compete with). A mention and a citation are different things, so each has its own number. For the wider tool picture, see the best AI visibility tools for healthcare and Ahrefs Brand Radar vs Curve.
The four numbers to read together
Share of voice on its own can mislead. A practice can hold a large share on a handful of questions where few brands are named at all. Read it with three other numbers:
| Number | What it measures | What a low number usually means |
|---|---|---|
| Mention rate | How often AI answers name you | Assistants answer your patients without bringing you up |
| Citation rate | How often AI answers cite a page on your site as a source | AI is not using your pages as evidence, even when it names you |
| Share of voice | Your share of the mentions among the brands you compete with | Competitors are named more often than you on the same questions |
| Visits and bookings from AI | The visits from people who click a link in an AI answer, and the bookings those visits bring | Answers name you, but few patients click through or book |
The first three describe attention. The fourth describes appointments, and it is the one that pays. A share of voice that rises while bookings stay flat points to the wrong questions or the wrong landing pages, not to success.
What counts as a mention
- Every name a brand goes by. Count a rival whether an answer uses its full name, a short name or its website. A share of voice that misses a rival's short name is flattering and wrong.
- Your own names too. Patients and assistants shorten practice names, drop "LLC" and use the doctor's name. Count each of the names you go by.
- Citations are separate. Naming a brand and citing its website are different signals. Count them apart, because they move for different reasons.
One thing that does not count is a mention you manufactured. Google's guide notes that “seeking inauthentic "mentions" across the web isn't as helpful as it might seem.” (Google) Share of voice is a measure of what assistants already say, not a target to game.
Why share of voice moves week to week
Ask the same assistant the same question twice and you can get two different answers. Assistants also keep updating the pages they search and cite, competitors keep publishing, and new brands appear. So a single week's share of voice is a reading, not a fixed fact. Three habits keep it honest:
- Read the trend. Compare several weeks, and treat a one-week dip as noise until the next readings confirm it.
- Compare like with like. Keep the same questions and the same competitor list when you compare periods. Adding a rival lowers everyone else's share.
- Split by assistant. Each assistant has its own sources and habits. Look at each one on its own before you average them.
Every tool measures from the outside, too. Google notes that “No third-party tool has access to our internal ranking or AI systems.” (Google) Share of voice always comes from asking assistants real questions and counting what they say.
Which questions and competitors to track
- Questions where patients choose. Focus on the questions where a patient is picking a provider: commercial, comparison and local questions, not only general information.
- Brand questions in their own topic. Questions that already name your practice will mostly name you. Group them into their own topic so they don't lift your share on the questions where patients haven't chosen yet.
- Local questions by place. Patients ask for care near them, so write the city into the local questions, once for each city you serve.
- The rivals AI actually names. Track the brands AI names for your patients' questions, not only the ones you think of as rivals. A share of voice that leaves out a real rival is flattering and wrong.
From share of voice to a plan
A gap is only useful if it tells you what to publish. Start with the questions where a competitor is named and you aren't. Read those answers: what they say about the brand they recommend, and which pages they cite, shows what AI treats as evidence.
- Write or update the page. Answer the gap question plainly on the page that owns the topic, at a pace your clinicians can review.
- Check the sources AI trusts. Look at the directories, publishers and other sites AI cites for that question, and make sure anything they say about you is accurate. See where AI gets healthcare answers.
- Measure the effect. Compare mention rate, AI visits and bookings on that topic before and after the page goes live.
Curve's AI Visibility shows where competitors are named and you aren't, who leads each topic, and which sources AI cites. It turns what it finds into a weekly roadmap sized to what your clinicians can publish, with medical topics flagged for clinical review.
Share of voice and bookings
Share of voice measures attention, not appointments. The number that pays is what those answers lead to: the visits from people who click a link in an AI answer, and the bookings those visits bring. Curve's AI Visibility ties AI answers to the visits and bookings they bring you, and measures what each published piece changes. See from AI search traffic to bookings.
What This Looks Like in Practice
In one AI Visibility program we've run, for a HIPAA-focused healthcare software brand, Curve's team tracked the questions buyers ask AI assistants, found where competitors were named and the brand wasn't, and published pages to close those gaps. About five weeks in:
- AI assistants named or cited the brand in 53% of their answers to its 40 core buyer questions (104 of 196), across ChatGPT, Google AI Overviews, Google AI Mode, Perplexity and Claude.
- Across 184 real buyer questions and 912 AI answers, its site was cited in 236 answers, more than any competitor's and more than 2.5 times as many as the nearest one (89).
- 47 of the new pages were already cited by AI assistants within six days of going live.
- One new page brought in more than half of the brand's unpaid ChatGPT visits in its first week.
How Curve Compliance helps
AI Visibility is a feature in Curve Compliance, and Curve also offers it as a managed service. AI Visibility shows how often AI assistants, including ChatGPT, Google AI Overviews, Google AI Mode, Perplexity, Claude and Gemini, name and cite your practice for the questions your patients ask. It reports mention rate (how often AI answers name you), citation rate (how often they cite your site) and share of voice (your share of the mentions among the brands you compete with). It ties AI answers to the visits and bookings they bring you. Every week you get a plain-language summary of what changed, and a one-page report to share. It's built for healthcare: only the marketing question you track is sent to AI assistants, screened for PHI first, and never anything about a patient. Curve is SOC 2 Type II and signs a BAA on every plan. See AI Visibility in Curve and what AI visibility is.
With the managed service, Curve's team sets up your questions, competitors and topics, writes the pages on your roadmap, and makes the technical fixes that help AI assistants read your site. Your clinicians review and approve anything medical before it goes live. If your developer manages your site, Curve's team hands them the exact fixes. Each month, Curve's team walks you through your results on a call and sends a one-page report. AI Visibility is available on request: book a call to get started.
Beyond AI Visibility, Curve Compliance replaces browser ad pixels with one script, sends conversions server-side to Meta, Google Ads, TikTok, Microsoft Advertising and LinkedIn, and strips PHI before data reaches an ad platform (Directory entry).

What counts as a mention in AI share of voice?
An answer that names your brand. A citation of your page is a separate signal, which Curve Compliance's AI Visibility reports as citation rate.
Why does AI share of voice change week to week?
Because AI answers vary from one ask to the next, assistants keep updating the pages they cite, and competitors keep publishing. Read share of voice as a trend across several weeks, not a single reading.
Which competitors should I track?
The brands AI actually names for your patients' questions, not only the ones you think of as rivals. Curve Compliance's AI Visibility shows where competitors are named and you aren't, and who leads each topic.
Is AI share of voice the same as citation rate?
No. Share of voice is your share of the mentions among the brands you compete with, while citation rate is how often AI answers cite your site. Curve Compliance's AI Visibility reports both, plus mention rate.
