What Is AI Share of Voice?

RivalScope Team2 min read
AI share of voice is the percentage of AI-generated responses in your category that mention your brand, measured relative to your competitors.

Why It Matters

Share of voice has long been a marketing metric in advertising and PR. In the AI context, it answers a critical question: when people ask AI assistants about your industry, how often does your brand come up compared to the competition?

If ten relevant prompts are asked across AI platforms and your brand appears in three responses while a competitor appears in seven, your share of voice is significantly lower — and you are likely losing potential customers at the point of discovery.

How It Is Calculated

AI share of voice is typically calculated by:

  1. Defining a set of prompts that represent how your customers search (e.g., "What is the best project management tool for small teams?")
  2. Running those prompts across major AI platforms
  3. Recording which brands are mentioned in each response
  4. Calculating each brand's mention percentage across all responses

For example, if your brand is mentioned in 40 out of 100 total responses and a competitor is mentioned in 60, your share of voice is 40% and theirs is 60%.

How to Improve It

Improving your AI share of voice requires strengthening the signals AI platforms use to decide which brands to recommend:

  • Increase your presence on authoritative sources — more high-quality mentions across the web lead to more AI recommendations
  • Improve content quality and structure — make it easy for AI systems to find and reference your information
  • Address gaps — identify prompts where competitors appear but you do not, and build the authority needed to be included

RivalScope calculates your AI share of voice automatically, tracking your brand against competitors across five AI platforms so you can see exactly where you stand.

Frequently asked questions

How is AI share of voice different from traditional share of voice?

Traditional share of voice measures brand presence in advertising or media coverage. AI share of voice measures how often AI assistants mention your brand relative to competitors in their generated answers.

What is a good AI share of voice?

It depends on your market and the number of competitors. As a general rule, you want your share of voice to be at least proportional to your market share — and ideally higher, since AI visibility is still a competitive advantage early movers can capture.
