Overview
About 제스트컴퍼니(ZESTCOMPANY) (researcher summary)
Since 2017, 제스트컴퍼니(ZESTCOMPANY) has run search marketing from Gyeonggi-do, South Korea, and it now describes itself as a specialist in generative engine optimisation, answer engine optimisation and SEO. Its tagline states the goal directly: getting brands recommended in AI search.
The agency's method is measurement-led. It sets target questions that a brand should appear for, then tracks how often the brand is mentioned and how often its pages are cited as sources in ChatGPT, Gemini, Perplexity and Claude, treating mentions and citations as separate measures. It also carries out the work itself, from site structure and structured data through to producing the content. Declared services are split evenly across AI SEO and GEO, SEO, local SEO, content marketing and digital marketing.
The team is in the 10 to 49 range, its profile lists English as a working language, and typical project budgets run from $10,000 to $25,000. ZESTCOMPANY suits brands with a substantial budget that want an AI search optimisation agency in South Korea able to show, question by question, how visible they are in AI assistants.
