AI share of voice measures how often your brand appears in ChatGPT, Perplexity, and Gemini answers — the most important B2B competitive metric.
Traditional share of voice (SOV) measures how visible your brand is across paid media, organic search, and earned media. Higher SOV correlates with higher market share — this principle has held for decades.
AI is creating a new variant of this metric that may matter more: AI share of voice.
AI SOV measures how often your brand appears in AI-generated answers, relative to your competitors, when buyers ask purchase-intent questions.
Traditional SOV is influenced heavily by media spend and content volume. A company can buy its way to a higher traditional SOV with ad budget.
AI SOV is determined by:
Budget alone cannot buy AI SOV. It requires content and technical investment — which means the playing field is more level than traditional SOV.
The process:
If your brand appears in 15 of 60 total brand mentions across all prompts and engines, your AI SOV is 25%.
TrueCite's [MentionShare tracking](/features/mentionshare) and [Competitor Intelligence](/features/competitor-intelligence) automate this calculation and track it over time, so you can see how your AI SOV changes as competitors publish new content or get new reviews.
AI SOV reveals what your competitors are doing to win AI citations:
This intelligence directly informs your content strategy: publish the content your competitors are missing, structured the way AI engines prefer, targeting the prompts where AI ignores your brand. [Prompt Performance](/features/prompt-performance) shows you exactly which queries need the most attention.
Based on TrueCite's platform data:
Most brands that haven't invested in AEO have sub-10% AI SOV — which means there is significant upside available through structured content and schema optimization. [Track your AI share of voice](/sign-up) — your first MentionShare scan is free.
