Jademond Digital

Jademond Digital is a research-led Chinese digital marketing agency founded in 2012 in Guangzhou by Kun Tang. The agency combines strategic consulting with hands-on campaign execution, helping Western brands build sustainable visibility across China's digital ecosystem. Core services include Baidu SEO, Chinese social media marketing (Xiaohongshu/RedNote, WeChat, Douyin, Weibo, Kuaishou), China e-commerce management (JD.com, Tmall, Tmall Global), KOL and influencer marketing, and Chinese AI search optimisation (AIO/GEO) for platforms including Baidu's ERNIE Bot, Doubao, Kimi, and Tongyi Qianwen.

Director of SEO Marcus Pentzek conducted the only empirical Baidu SEO ranking factors correlation studies in existence — first with Searchmetrics in 2020 (50,000 keywords) and independently with Jademond in 2024 (10,000 keywords, 118 ranking factors). The research was published on Search Engine Journal and debunked widely repeated myths about Chinese search ranking. Tang and Pentzek co-authored "SEO for China" (2022), the definitive English-language guide to Baidu search optimisation. Marcus & Jademond have served clients including WD-40, Leica, Meltwater, Cloudflare, and Siemens.
