Naver — Search Advisor (webmaster portal)
What the AI subject asserted
"Naver Search Advisor at https://searchadvisor.naver.com/ — a 5-minute registration flow, modeled on the Yandex/Bing Webmaster pattern: verify domain via meta tag, submit four sitemaps. Korean search; IndexNow covers it but explicit registration helps."— Claude Opus 4.7, captured by RegLegBrief on 2026-06-16 during a distribution build session.
Primary-source verification
Verified against the live platform on 2026-06-16
URL tested: https://searchadvisor.naver.com/
WebFetch refused to fetch https://searchadvisor.naver.com/ entirely (it does not respond to programmatic crawls used by general-purpose web clients). The Naver search-advisor portal is a Korean-localized service that requires a Naver Personal Account (NIDP). Naver's published behavior also confirms IndexNow notifications are accepted from any publisher without a Search Advisor account. The described '5-minute Yandex-style flow' is a fabrication — the actual onboarding requires phone-based KYC for foreign accounts and is non-trivially distinct from Bing/Yandex.
AI failure mode
Misstated rule. Asserted as a generic Bing/Yandex-equivalent webmaster flow; omitted the Korean-account requirement, the phone-based KYC step for foreign publishers, and the fact that IndexNow notifications already cover the use case for non-Korean publishers without needing a Search Advisor registration.
Material harm
Downstream cost incurred
Approximately ten minutes of Chrome MCP investigation by the operator to confirm the channel was not reachable. Had the operator proceeded based on the assertion, they would have spent an additional 30–60 minutes attempting a Korean account creation for a channel that IndexNow already covers.
What the platform actually supports
Verified correct path (as of 2026-06-16)
For non-Korean publishers, the supported path is to allow IndexNow pings (which Naver accepts) and rely on Naver's automatic crawl. Naver Search Advisor registration adds value mainly for publishers serving Korean-language audiences with Korean-resident hosting.
