SEO & GEO Expertise — Built Across Real Industries
Aiden Hoang Nguyen (MBA, Western Sydney University) is the founder of Ktdigital — a Ho Chi Minh City-based SEO & GEO consultancy. Over 10+ years, Aiden has built deep hands-on experience across education, global immigration law, healthcare, and entertainment — industries where trust, content authority, and precise search intent determine whether a brand wins or loses online.
Among Aiden's areas of focus is GEO (Generative Engine Optimization) — a discipline he has been actively applying since the early days of AI search, helping clients structure content that earns citations from ChatGPT, Gemini, and Perplexity. His immigration law client now appears as a primary AI-cited source for "US immigration lawyer in Singapore and Vietnam."
Over 50% of Google searches in 2025 now end without a click — users get their answers directly from AI-generated summaries before reaching any website.

Brands that appear in AI-generated answers see 3–5× higher trust signals and conversion intent than brands found only through traditional organic search results.
