ASVC queries 4 LLM engines (ChatGPT, Claude, Gemini, Perplexity) via the DataForSEO LLM Responses API. For each brand under test, the tool runs 12 paired query sets. Each pair has a branded variant and a head term variant, both scoped to the same brand position. The 12 pairs cover the canonical question shapes a prospect asks (what is, is X legit, X reviews, best X, top X 2026, X for startups, X vs Y, alternatives to X, recommended X).
Each pair runs across all 4 engines. That produces 48 datapoints per brand audit. Citation is logged when the brand domain or named entity is present in the LLM response. The tool returns a per-engine citation rate for branded queries, a per-engine citation rate for head terms, and the gap score.
