Open Time is a specialized GEO (Generative Engine Optimization) and AI search optimization agency headquartered in Busan, South Korea. Founded in 2023, the agency has quickly positioned itself as a niche player focused on helping Korean professionals and B2B service companies gain visibility in AI-generated search results. With a proprietary K-GEO methodology, Open Time addresses the growing shift from traditional search engines to AI answer engines like ChatGPT, Perplexity, Gemini, Grok, and Claude, as well as Naver's AI Briefing.

The agency's core offering revolves around diagnosing and improving how AI engines perceive and cite a client's brand. Open Time provides a free, 30-second diagnostic tool that checks a website's technical readiness for AI crawlers, including robots.txt permissions, JSON-LD structured data, sitemaps, and llms.txt. It then measures actual AI response inclusion by querying the top five global AI engines and Naver AI Briefing, providing a detailed report on brand mentions, competitor citations, and prioritized improvement steps. This data-driven approach, backed by over 200 SEO and digital marketing projects, gives clients a clear roadmap to becoming the "AI's default answer" in their category.

Open Time's services span GEO consulting, AI search optimization, AEO (Answer Engine Optimization) marketing, technical SEO, content structuring, and K-GEO implementation roadmaps. They tailor strategies for regulated professional sectors such as healthcare, law, tax and accounting, education, real estate, and beauty and wellness, taking into account Korea's unique search ecosystem, advertising regulations, and EEAT signals. The agency's focus on both global and local AI platforms makes it a rare specialist in the Korean market.

Pricing is project-based, with typical budgets ranging from $5,000 to $10,000 per project and project durations of 3-6 months. This positions Open Time as an accessible option for mid-sized and enterprise businesses looking to invest in AI search visibility without committing to long-term retainers. The free diagnostic tool also lowers the barrier to entry, allowing potential clients to assess their current AI search standing before engaging.

Open Time is best suited for Korean B2B service companies and professionals in regulated industries who rely on client referrals and local reputation. Law firms, tax accountants, medical clinics, and dental practices will find particular value in the agency's ability to optimize for both global AI engines and Naver's AI Briefing. The agency's small team size (1-9) means personalized attention, but may limit capacity for very large or multi-market campaigns.

Overall, Open Time offers a compelling, specialized solution for an emerging need. As AI-generated answers increasingly replace traditional search results, businesses that fail to appear in these responses risk losing significant organic traffic. Open Time's methodical, measurement-based approach provides a clear path to securing that visibility. While still a young agency with a limited track record of public client reviews, its innovative free diagnostic tool and deep focus on the Korean market make it a strong contender for any local professional service firm serious about AI search optimization.
