Opentime

OpenTime (legal name PK Communications) is a Busan, South Korea–based digital marketing firm specializing in
K-GEO — Korean Generative Engine Optimization. We help professional-service businesses (medical, legal,
tax, accounting, education, real estate, construction, beauty) get cited in AI-generated search answers from
ChatGPT, Perplexity, Gemini, and Grok.

Our free 30-second diagnostic scores a website's AI-search visibility across seven factors — AI crawler
access (robots.txt), structured data (JSON-LD), answer-first content, and external citation signals — then
delivers a step-by-step improvement roadmap.

Built on 5+ years of hands-on SEO experience, OpenTime began developing its AI-search diagnostic in 2024 as
ChatGPT and Perplexity started replacing traditional search. Based in Busan, serving clients nationwide.
