Asia's SEO industry has outgrown its early years. Seoul now runs its own global SEO conference. Tokyo has its own community of Diamond-level Google contributors. Manila, Kuala Lumpur, and Singapore each have agency founders who train hundreds of practitioners a year. And a new discipline, GEO (Generative Engine Optimization), is being shaped in real time by people who were already leading traditional SEO.
This list rounds up ten of the most influential SEO voices working across Asia today, spanning Korea, Japan, Singapore, the Philippines, Malaysia, and beyond. Each one has built something durable: an agency, a tool, a book, a conference talk circuit, or a community that keeps growing.
