The Seoul AI Visibility Index — 25 Brands Ranked by AI Search Presence

BrandCited scanned 25 Seoul tech brands across 9 AI search engines. 84% scored below 40 — the threshold below which AI platforms will not cite a brand regardless of traffic, funding, or market position. The average score was 33/100. SOCAR led the index at 57/100.

AI visibility is not an extension of SEO. A brand can rank on page one of Google and score zero on BrandCited because AI platforms weight structured entity signals, crawler permissions, and content trust differently from keyword-based ranking algorithms.
