The Site Diagnostic's AI crawler check now includes Yeti, Naver's search crawler. Naver's AI Briefing is rapidly expanding across its integrated search in Korea, and allowing Yeti is the prerequisite for being cited there. Korean-language diagnostics now reflect Yeti blocking in scores and recommendations.
ChatGPT Search and Gemini gateways are now scored as well. Per OpenAI's official docs, ChatGPT Search visibility is gated by a dedicated crawler (OAI-SearchBot), and Google's official docs confirm Google-Extended controls both Gemini training and grounding (answer-time citations). Blocking either closes off that AI surface, so both checks were promoted to scored items.
llms.txt has been reclassified as a reference item. Google's official guidance states it is unnecessary for generative AI search, and no major LLM operator has officially adopted it — so following our evidence standard, it is still checked and displayed but no longer scored. It can remain useful for developer docs and AI agent scenarios.
Diagnostic results now include an AI Channel Alignment card — a reference view that reorganizes your existing signals for Google AI (AI Overviews · AI Mode) and Naver AI Briefing. It does not affect your score.
Some sites may see score changes from this update. Comparisons with previous results restart from your first scan under the new criteria.
