BSOVShare of Voice

Share of voice for {legal_name} vs named competitor set (%). EXTRACTION RULES: value = company mentions / (company mentions + Σ competitor mentions) × 100, expressed as 0-100 percent. CRITICAL — the Interbrand / Statista / Kantar BrandZ rank-position PROXY described below IS THE OFFICIAL COMPANY-SPECIFIC EXTRACTION METHOD, NOT peer substitution. DO NOT return type="rejected_peer_substitute" when applying this proxy — the proxy assigns a value to THIS company based on its OWN rank position. ACCEPTED EVIDENCE: (1) explicit SOV % from Sprout Social industry reports / Brandwatch / Talkwalker / Meltwater. (2) PROXY (competitor mention search): pick the top 4-6 named competitors in the company's primary category (the canonical competitor set for that GICS sector), count visible result-count surface mentions across Reuters + Bloomberg + FT in the last 12 months, then compute the company's share. (3) PROXY (rank-position, MOST RELIABLE for mega-caps): the company's OWN rank position in the relevant Interbrand / Statista / Kantar BrandZ top-100 — emit a proxy value calibrated to land in MONOTONICALLY INCREASING SOV bands: top-3 → value=55 (band 50+ → 90), top-10 → value=40 (band 25-50 → 75), top-25 → value=20 (band 10-25 → 55), top-50 → value=8 (band <10 → 30), otherwise (listed but below top-50) → value=5. A mega-cap consistently in the top-3 globally maps to value=55 under this proxy (top band 90); a top-25 brand maps to 55, a top-10 to 75 — so a stronger rank never scores below a weaker one. State which proxy was used in _reasoning. Return exact_numerical{value: <sov_pct_0_100>, unit: "percent", source_urls: [Interbrand/Statista ranking page + at least one corroborating media-monitoring source]}. Server applies ratio_band (<10 → 30, 10-25 → 55, 25-50 → 75, 50+ → 90). If {legal_name} appears in NO brand ranking (Interbrand / Statista / Kantar) AND no competitor-mention SOV can be computed — typical for niche / B2B / non-consumer brands — return type="absent" with reason="not_disclosed": share-of-voice is not measurable for it, and the server marks the index not_applicable. Do NOT force the value=8 floor onto an unranked brand, and do NOT invent a number from generic visibility.
