Share of voice in LLMs: what it is and how to calculate it for your clinic
Published on September 29, 2026
Metrics and Monitoring
If ChatGPT recommends 3 clinics for every patient question, the right question is not whether you're among them, but how often. Share of voice in LLMs is the slice of AI answers that mentions your clinic, and it's the most honest metric to know whether you're winning or losing the patient who decides via AI.
At Bincoo, while monitoring thousands of clinics, we've seen clinic owners completely change the conversation with their partners once they start presenting share of voice instead of Google impressions. The number is easy to understand and impossible to fudge.
More than 10,000 companies already use Bincoo to be recommended by ChatGPT, Gemini, and other platforms.
Why this metric is worth more than Google ranking
On Google, being on the first page already means visibility, even in tenth place. In AIs, the answer cites 3 to 5 names, and the first name carries more weight than the others. In other words: in LLMs there is no page two. You're inside the answer or you don't exist. Share of voice translates that contest into a single number you can track week after week.
How to calculate your clinic's share of voice
The formula is simple:
- Define your market prompts, the real questions patients ask AIs about your niche and city.
- Run all those prompts on the main AIs and count how often your clinic is cited.
- Add up the citations of all competitors that appear.
- Divide your citations by the total market citations and multiply by 100.
| Clinic | Citations in 30 prompts | Share of voice |
|---|---|---|
| Competitor A | 14 | 43.7% |
| Your clinic | 9 | 28.1% |
| Competitor B | 5 | 15.6% |
| Competitor C | 4 | 12.5% |
In this scenario, Competitor A is winning the AI patient almost one and a half times for every time you win. And most importantly: now you know it, instead of suspecting it.
This scenario illustrates another advantage of share of voice: it turns competition into a number. Instead of 'I think Dr. Smith is more famous in the neighborhood,' you have 'they answer 43.7% of patient questions and I answer 28.1%.' With that data, you can plan your comeback calmly.
| Scenario | Your 90-day goal |
|---|---|
| You lead | Protect the highest-ticket prompts |
| You lose narrowly | Attack the prompts where the leader appears and you don't |
| You have less than half of the leader | Build a content base before contesting |
What to do once you have the number
Share of voice becomes actionable when you break it down by topic. You might have 50% on cleaning and preventive questions, but 0% on implants, which are the highest-ticket ones. At Bincoo, the weekly report shows exactly that breakdown, the prompts where you disappear, and the content you need to publish to reappear.
Share of voice as a negotiation tool
Beyond guiding your content strategy, share of voice is a strong commercial argument. When a patient says 'the AI recommended another clinic,' you already know exactly who is winning and why. When it's time to present results to your partners, a weekly share of voice chart communicates in ten seconds what ten slides of Google impressions don't.
That's what the platform does: it monitors your terms, calculates your share of voice against competitors, and delivers the action plan to increase that number. All starting from the Essential plan, at R$ 39.00/month, no lock-in.
Conclusion
- Share of voice in LLMs is the slice of AI answers that cites your clinic.
- In AIs there is no page two: you're either in the answer or out of the decision.
- Measuring weekly by topic shows exactly where to invest in content.

Frequently asked questions
"What is share of voice in AI?"
It is the percentage of AI answers in which your clinic is mentioned or recommended, within the universe of prompts in your market. If out of the 100 typical questions in your niche the AI cites you in 12, your share of voice is 12%.
"What is a good share of voice for a clinic?"
It depends on local competition. In less contested markets, 30% to 50% is achievable within a few months. In capital cities and highly competitive specialties, getting above 15% already puts you among the most cited.
"How do I find out how often the AI cites my competitors?"
By running the same prompts you use for yourself on your competitors and counting citations. Bincoo does this automatically, showing each competitor's share of voice alongside yours.
"Is share of voice in AI the same as in Google?"
No. On Google you compete for link positions. In AIs you compete for mentions inside a generated answer, which cites few names, usually 3 to 5. That's why share of voice in LLMs is more concentrated and more valuable.
"How do I increase my share of voice in AIs?"
By publishing content that answers exactly the monitored questions, keeping reviews and external mentions active, and fixing gaps where you don't appear. Bincoo delivers that plan weekly starting from the [Essential plan, at R$ 39.00/month](/pt/planos).
