Share of Voice (AI)

AI Share of Voice is the percentage of AI responses in your category that mention your brand. It's market share, but for AI recommendations.

Ask ChatGPT "What's the best CRM?" a hundred times. If Salesforce shows up 80 times and you show up 12, your AI share of voice is 12%. Salesforce's is 80%. That gap is your problem.

How It's Calculated

The formula is straightforward:

AI Share of Voice = (Your brand mentions / Total brand mentions in category) x 100

But the calculation gets nuanced fast:

Which queries? "Best CRM" is different from "best CRM for startups" is different from "Salesforce alternatives." You need to track the queries that matter for your business.

Which platforms? Your share of voice on ChatGPT might be 15% while on Claude it's 3%. Each AI platform has different training data and different opinions about you.

What kind of mention? Being recommended is different from being listed. Being listed is different from being mentioned as a cautionary tale.

Why It Matters

Traditional share of voice measured brand mentions in media. That still matters. But AI share of voice is becoming the metric that predicts revenue.

Here's why:

AI recommendations drive purchases. Users trust AI suggestions the way they used to trust Google's first page.

AI share of voice is zero-sum. When a competitor gets mentioned, you often don't. There's only so much room in a generated response.

It compounds. AI systems learn from patterns. Brands that get mentioned more tend to keep getting mentioned more. The rich get richer.

Benchmarks

There's no universal benchmark — it depends on your category. But some patterns hold:

Position	Share of Voice	What It Means

Category leader	30-50%+	AI's default recommendation
Strong contender	15-30%	Consistently mentioned, not dominant
On the radar	5-15%	Shows up sometimes, not reliably
Invisible	<5%	AI barely knows you exist

If you're below 5%, AI isn't ignoring you by accident. It genuinely doesn't have enough information to recommend you. That's a content and authority problem, not a luck problem.

How to Measure It

You can do it manually. Ask each major AI platform the same set of queries, record who gets mentioned, build a spreadsheet. It works. It's also tedious and impossible to do at scale.

Or you can use Renown's competitive tracking. It monitors AI responses across ChatGPT, Claude, Gemini, and Perplexity for your key queries and calculates share of voice automatically, over time.

How to Improve It

Diagnose the gap. Which queries are you missing? Which competitors own those queries? Start there.

Build authority on trusted sources. AI pulls from Wikipedia, G2, Reddit, industry publications, and review sites. If you're absent from these, you're absent from AI.

Create citable content. GEO tactics that work: add statistics, cite sources, use clear structure.

Monitor consistently. Share of voice shifts. New competitors enter. AI models update. Monthly tracking catches trends before they become crises.

Fix inaccuracies. If AI says wrong things about you, that's damaging your share of quality mentions. Brand monitoring catches these.

The Uncomfortable Truth

AI share of voice is becoming a leading indicator of market share. The brands AI recommends today are the ones buyers shortlist tomorrow. If your competitors own AI recommendations in your category and you don't, that's not a marketing problem. It's a business problem.
