Share of voice measures your brand’s slice of AI-generated answers in your category — how often you appear versus named competitors when shoppers ask product questions.
Overview
Share of voice measures your brand’s slice of AI-generated answers in your category — how often you appear versus named competitors when shoppers ask product questions.
Why it matters for ecommerce
Ecommerce stores compete on discovery, not just clicks. If AI engines recommend competitors more often, you lose consideration before a customer ever visits your site.
How Surfacely measures this
Surfacely runs live probes across ChatGPT, Claude, Perplexity, and Gemini, then compares brand mentions and citations against competitors surfaced in the same answers.
Where to find this in your report
Share of voice appears in the AI Visibility section when competitors are detected in probe answers. Compare your mention rate against named rivals in the same prompts.
How to improve it
- Identify prompts where a competitor dominates and inspect which pages AI cites for them.
- Strengthen differentiation copy on PDPs — AI favors clear, comparative product facts.
- Ensure variant-level URLs and GTINs are exposed so AI can distinguish your catalog from marketplaces.
- Monitor weekly to catch share shifts after competitor site updates.
