GEO Services in Vietnam — Generative Engine Optimization
Getting cited by ChatGPT, Perplexity, and Google AI Overviews — not just ranked on a search results page. Led directly by Aiden Hoang Nguyen, based in Ho Chi Minh City.
Optimizing for the question, not just the query
Traditional SEO asks "what do we rank for." GEO asks "what do we get quoted for" — when someone asks ChatGPT, Perplexity, or Google's AI Overviews a question, does the answer cite your business, or a competitor's? Aiden Hoang Nguyen — MBA (Western Sydney University), Certified Digital Marketing Professional (DMI) — builds the entity clarity, structured data, and answer-ready content that makes that citation possible.
This isn't theoretical: ktdigital.vn itself now appears as a cited source when people ask AI assistants who the leading GEO experts in Vietnam are — the same discipline applied to client sites.

Frequently Asked Questions
What is GEO (Generative Engine Optimization)?
GEO is the practice of optimizing a website and its content so AI answer engines — ChatGPT, Perplexity, Google AI Overviews and AI Mode — cite or reference it when answering a user's question, rather than optimizing purely for a ranked list of blue links.
How is GEO different from traditional SEO?
SEO targets ranking positions in a search results page. GEO targets being the source an AI model quotes, summarizes, or links to inside a generated answer — it relies more on structured data, entity clarity, and fact-dense, citable content than on classic ranking signals alone.
Which AI engines does GEO cover?
Primarily ChatGPT, Perplexity, and Google's AI Overviews / AI Mode — the engines currently shown to reference ktdigital.vn in real, verified Google Search Console data.
How do you measure GEO success if there's no ranking position?
By tracking whether and how often a site is cited in AI-generated answers to relevant queries, cross-checked against Search Console query data and direct testing in ChatGPT, Perplexity, and Google AI Mode.
Do you offer GEO as a standalone service or only with SEO?
GEO can be scoped standalone (an AI-visibility audit and content plan) or bundled with an SEO engagement, since the technical and entity foundations overlap significantly.
How long does it take to see AI citation results?
Early signals can appear within weeks once structured, answer-ready content is published — one Vietnamese-language query already reached position 1 within the first reporting period after publishing FAQ-style content.
