AI Search Share of Voice for My Brand

By ChatLooker Team · Updated 2026-06-28

AI search share of voice for my brand is the percentage of buyer prompts where ChatGPT, Perplexity, or Google AI Overviews mention or recommend my company versus competitors on the same query set. To calculate AI search share of voice for your brand, divide prompts where you appear by total tracked prompts — then compare each rival's rate on identical queries. AI search share of voice for my brand differs from Google impression share: it measures synthesized AI recommendations, not blue-link visibility.

How to calculate AI search share of voice for my brand

AI search share of voice for my brand uses a fixed prompt universe — thirty to one hundred buyer queries from sales discovery. Run each prompt across target engines. Count appearances, top-3 positions, and competitor names. AI search share of voice for my brand equals (prompts with my brand) ÷ (total prompts) × 100.

Example: 22 appearances across 50 "best AI visibility tool" prompts = 44% AI search share of voice for my brand. If the category leader appears in 38, their share is 76% — quantifying the gap for LLMO priorities.

AI search share of voice for my brand vs mention rate

AI search share of voice for my brand can rise while top-3 presence stalls — passing references in paragraph five inflate share without shortlist impact. Track both:

  • Share of voice — any mention across the prompt set
  • Top-3 presence share — shortlist inclusion buyers act on

Insight (top3-presence-gap): Top-3 presence in AI answers is often lower than raw mention rate — a brand can be named without being recommended.

Improving AI search share of voice for my brand

  1. Publish missing alternatives pages where competitors dominate share
  2. Apply answer-first structure on category and comparison URLs
  3. Fix entity inconsistency — same product name on homepage, G2, and schema
  4. Re-measure monthly on the identical prompt set
