Stridec is a Singapore-based GEO/SEO agency that helps brands get recommended by AI searches such as Google, ChatGPT and Claude. We serve clients across Southeast Asia, Vietnam included, as well as North America. GEO, AEO, AIO and AI SEO are the market’s names for the same job: getting your brand named inside the answer, not just listed below it.
Prices and scope are on the GEO services and pricing page. Our other market pages are GEO agency Singapore, GEO agency Malaysia and GEO agency Thailand. Đọc trang này bằng tiếng Việt: Dịch vụ GEO tại Việt Nam.
In Vietnam, the language of the question changes the answer
Ask Google for “the best GEO agency in Vietnam” in English, then ask the same thing in Vietnamese, and you get two different lists of companies. The engines answer from the pages written in the language of the question. A brand that only has English pages can be named for English questions and missing for the Vietnamese ones, and those are the questions local buyers type.
We checked this from a Vietnamese location on 4 November 2026 in Google AI Mode. The English question named four agencies. The Vietnamese question named five, and only one of them appeared in both answers. Same market, same day, almost entirely different names.
So for a Vietnamese brand the first job is the one we start with everywhere, done in both languages: make it easy for the engine to say what you are, who you serve and where, in English and in Vietnamese.
What a GEO agency does
Generative engine optimisation is the work of getting your brand named inside the answers AI engines write. The engines are Google AI Overviews, Google AI Mode, Gemini, ChatGPT and Claude. We measure whether your name appears in the answer text, which is different from your website appearing as one of the sources underneath. Only the first one brings you enquiries.
Here is what usually goes wrong. A brand publishes more than anyone in its category and still isn’t quoted, because its pages are written in adjectives. “Leading” and “professional” can’t be lifted into an answer, because they say nothing a reader could check. Numbers can. When we built Alva’s own coffee store, every phrase Google quoted from it was a fact: a price, a bottle size, a delivery day. Not one adjective survived.
What is in scope
- What you are, in one sentence. Brand, product type, customer and outcome, written plainly and held the same across every page, title and profile, in English and Vietnamese.
- A live check of your market. For each question a buyer asks, in each language: does an AI answer appear, who is named, and which pages the engine is reading. For Vietnam we run that check from a Vietnamese location.
- A target list that can be won. Each question has to show an AI answer, draw on several sources and carry buying intent before it gets budget.
- Pages built to be quoted. At least 8, 15 or 25 pieces a month, depending on the tier, in Vietnamese, English or both.
- Brand mentions from the S$4,500 tier, and link building at S$8,000.
- A monthly citation snapshot per engine, with the question, language, market and date on every reading.
Outside sources carry more weight than your own site
One of our clients, a branding agency, showed this clearly. Across 40 Google AI Overview results in September 2026, a business that appeared on one source was named 27% of the time. A business on three or more sources was named 87% of the time. The engines trust what several independent pages agree on.
For Vietnam, those sources are often Vietnamese-language “top companies” articles, directories and industry sites. Part of every engagement is finding which of those the engines read for your questions, then getting your brand onto them with the same description you use on your own site.

Proof we can show you
Qwang Coffee is Alva’s own Shopify store, selling bottled Vietnamese coffee. The domain was registered on 23 August 2026, with no backlinks, no ads and no reviews. It was indexed within an hour, on page one within 24 hours, and cited in Google’s AI Overview within 48 hours. It was listed first on 3 of 5 commercial questions we tracked in Singapore. Within a week every Google AI Overview citation was gone, while ChatGPT still named Qwang first. We keep that part in because it is how the engines behave.
AeroChat, Alva’s own software product, is where the method started. In early 2026 it reached its first Google AI Overview in under three weeks, with 343% growth in impressions, 127% growth in clicks and a 74% share of branded search, period over period.
We don’t have an office in Vietnam. We run the work from Singapore and check AI answers from a Vietnamese location, because the engines answer differently depending on where, and in which language, the question is asked.
Frequently asked questions
What is a GEO agency, and what does dịch vụ GEO mean?
A GEO agency does generative engine optimisation: it works to get your brand named inside the answers that AI engines write, such as Google AI Overviews, Gemini, ChatGPT and Claude. In Vietnamese the service is usually called dịch vụ GEO or tối ưu AI search. GEO here has nothing to do with geography.
Does ChatGPT or Google AI answer differently in Vietnamese?
Yes. The engines answer from pages written in the language of the question. On 4 November 2026 we asked Google AI Mode for the best GEO agency in Vietnam in English and in Vietnamese, and only one agency appeared in both answers. A brand that wants Vietnamese buyers needs Vietnamese pages the engine can quote.
Can a Singapore agency do GEO for a Vietnamese brand?
Yes. The engines are the same in both countries. What changes is where you check from, which language you check in, and which local sources the engines read. Stridec checks AI answers from a Vietnamese location, in Vietnamese and English.
Is GEO different from SEO for a Vietnamese website?
SEO works on where your page ranks in the list of links. GEO works on whether your brand is named in the answer written above that list. The two share foundations, such as clear pages and outside mentions, but GEO is measured by whether your name appears in the answer, engine by engine.
Which sources do AI engines read for Vietnamese questions?
For buyer questions they lean on Vietnamese-language articles that list top companies, directories, industry sites and the Google profiles of the businesses themselves. The engines trust what several of these agree on, so being described the same way on several of them matters more than any one page.
Can I do GEO myself?
Yes. The AI Search Playbook, second edition, sets out the method for US$297, tested on six real businesses, wins and failures included. Most clients hire an agency for the publishing volume and the monthly readings per engine.
