How to track AI visibility in South Korea
Track the engines available in South Korea on a schedule, not once; our trackers for ChatGPT, Perplexity, Gemini, Claude, Grok, Google AI Overviews and Google AI Mode show what each answer contains.
Cituna tracks all seven engines, ChatGPT, Perplexity, Gemini, Claude, Grok, Google AI Overviews and Google AI Mode, from the $39 Starter, and joins the result to Google Search Console so a movement in South Korea can be checked against real clicks. Then it does the work: it generates the fix for each gap, its AutoSEO writes and publishes the articles that answer the questions you are missing, and Claude or any other AI agent can work through the results over MCP. The most useful output is usually not the score but the competitor list, because it tells you which brands are being named in your place in this market.
