Share of voice is how often AI assistants name your store when shoppers ask about your category — the clearest measure of whether you're actually being recommended, not just known.
What share of voice means
Being known and being recommended are different. An assistant might describe your store warmly when asked by name, yet never mention you when a shopper asks "where should I buy X?" Share of voice measures the second, more important thing.
How we measure it
Each month, Pulse asks around thirty realistic shopper questions across ChatGPT, Claude, Gemini, and Perplexity — cold, with your store never named. You see how many answers named you, who got named instead, and how that count moves over time.
The pages that decide
Assistants build those answers from pages they trust — best-of lists, review sites, forums. Pulse surfaces the specific pages the assistants read before answering, flagged by whether they feature you or your rivals. That list is your PR to-do: get featured there, and the answers change. For a pitchable site that features your rivals but not you, Draft the pitch writes a grounded outreach email you can personalize before sending — so working the list is a few edits, not a blank page.
