Quick Definition
Share of Buyer Voice (SBV) is the percentage of your addressable buyer market that can discover your business through AI-powered research journeys.
It combines:
- Buyer Universe size
- Prompt Universe coverage
- AI visibility
- AI recommendations
- Competitive presence
The higher your Share of Buyer Voice, the larger the percentage of buyers who can find you during AI-assisted research.
Why Share of Buyer Voice Matters
Traditional marketing metrics tell us:
- how much traffic we receive
- how many impressions we generate
- where we rank
- how often we are mentioned
What they don’t tell us is:
How much of the buyer market can actually see us when making purchasing decisions.
As AI research becomes more common, buyers increasingly rely on AI assistants to:
- discover vendors
- compare providers
- evaluate alternatives
- build shortlists
If your company is missing from those conversations, a portion of your market effectively becomes unreachable.
Understanding the Buyer Universe
The Buyer Universe represents all potential customers who may purchase your solution.
For example:
An Employer of Record provider serving Australian companies hiring in the Philippines may have:
- 20,000 potential buyers annually
An AI SEO agency may have:
- 10,000 potential buyers annually
A SaaS platform may have:
- hundreds of thousands of potential buyers
Not all buyers research in the same way.
Increasingly, many begin their journey inside AI platforms.
Understanding the Prompt Universe
The Prompt Universe is the collection of questions buyers ask while researching solutions.
Examples include:
Discovery Prompts
- Best EOR providers in the Philippines
- Top AI visibility agencies
- Best payroll outsourcing companies
Comparison Prompts
- Deel vs Remote
- Local EOR vs Global EOR
- AI SEO vs traditional SEO
Evaluation Prompts
- How do I choose an EOR provider?
- What should I look for in an AI agency?
- Which AI visibility platform is best?
Every prompt represents a potential buying interaction.
The Relationship Between AI Share of Voice and Share of Buyer Voice
AI Share of Voice and Share of Buyer Voice are related but different.
| Metric | Measures |
| AI Share of Voice | How often your brand appears |
| Share of Buyer Voice | How much of the buyer market can discover you |
Think of AI Share of Voice as visibility.
Think of Share of Buyer Voice as opportunity.
One measures presence.
The other measures reach.
How Share of Buyer Voice Works
Imagine:
- 100,000 potential buyers
- 40% use AI assistants during research
- Your company appears in only 10% of relevant prompts
Your effective visibility becomes significantly smaller than your actual market size.
Even though demand exists, buyers may never encounter your brand.
This creates what we call:
Invisible Demand
Invisible Demand is demand that exists but cannot discover your company because you are absent from the research journey.
Why Share of Buyer Voice Matters More Than Traffic
Traffic measures visitors who already found you.
Share of Buyer Voice measures buyers who could have found you but didn’t.
This distinction matters because:
- Lost visibility creates lost pipeline.
- Lost pipeline creates lost revenue.
- Lost revenue is often invisible.
Many businesses focus exclusively on website traffic while overlooking the buyers they never had a chance to attract.
Calculating Share of Buyer Voice
A simplified model looks at:
| Component | Example |
| Buyer Universe | 50,000 buyers |
| AI Adoption Rate | 35% |
| Relevant Prompt Coverage | 500 prompts |
| AI Share of Voice | 20% |
| Estimated Buyer Reach | Resulting SBV |
The exact calculation varies by industry, but the objective remains the same:
