If you want your brand named when someone in Vietnam asks ChatGPT, Gemini or Google for a recommendation, you need an agency that does GEO, not only classic SEO. This list compares seven agencies that sell GEO or AI SEO to Vietnamese businesses. For each one it covers where they are based, what they offer, what they charge where they publish it, and who they suit.
Disclosure: Stridec wrote this comparison and placed itself first. Read our entry with that in mind, and read the others for the cases where they are the better hire. We say where those are. Every figure attributed to another agency is that agency’s own published claim, taken from its website on 4 November 2026, with a link so you can check it.
The short version
- Stridec is the choice if you want your brand named inside the AI answer, not just listed as a source. Its Brand Authority Directive makes your business the one the engines understand most clearly and can quote most precisely, in Vietnamese and English.
- SEONGON is the large Vietnamese agency for big private companies and state groups, on 6 to 9 month programmes.
- Hashmeta Vietnam publishes GEO prices from 60 million đồng a month, with no long-term commitment.
- TopOnSeek and SEODO are established Vietnamese SEO agencies with dedicated GEO services.
- Rankpage Vietnam sells combined SEO and GEO packages from 18.5 million đồng a month.
- Saigon Digital works mainly for international B2B brands, in English.
How we compared them
We started from what the AI engines themselves recommend. On 4 November 2026 we asked Google AI Mode, from a Vietnamese location, for the best GEO agency in Vietnam, once in English and once in Vietnamese. The two answers named almost entirely different agencies, which is a finding in itself: the language of the question changes who gets recommended. We added agencies with a dedicated Vietnamese GEO service page.
Then we read each agency’s own website and recorded only what it states: location, services, prices and numbers. Where an agency does not publish something, we say so rather than guess. Agencies are left out when we could not find a GEO service page on their site or could not load it. GTV SEO, which Google named, is not here because its GEO service page has been taken down.

1. Stridec: best for getting your brand named in the answer, not just cited
Best for: Vietnamese and regional brands that want AI engines to recommend them by name, in Vietnamese and English, with SEO and GEO handled as one job.
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, and we have worked in search since 2001. We don’t have a Vietnamese office. We run the work from Singapore and check AI answers from a Vietnamese location, in both languages, because the engines answer differently depending on where and how the question is asked.
How we work: AI doesn’t pick the biggest brand. It picks the one it understands most clearly and can quote most precisely. Our Brand Authority Directive makes that your brand. We write down exactly what your business is, who it serves and how it is different, with no marketing language, and hold it the same across your site and profiles. Then we get independent sources to describe you the same way, because the engines trust what several pages agree on. We judge the work by one number: how often your brand is named inside the answer, in Vietnamese and English.
Prices: S$2,500 a month for GEO Foundations (one channel, Google or ChatGPT), S$4,500 for GEO Authority (Google and ChatGPT) and S$8,000 for Full-Spectrum GEO + SEO (Google, ChatGPT and Claude). Details are on the pricing page.
Proof: the method was built on founder Alva Chew’s own businesses first. AeroChat, Alva’s own software product, reached its first Google AI Overview in under three weeks in early 2026. Qwang Coffee, Alva’s own Shopify store selling bottled Vietnamese coffee, was cited in a Google AI Overview within 48 hours of its domain being registered, in Singapore. Both are on the case studies page.
Choose someone else if: you want a large local team in the room in Hanoi or Ho Chi Minh City, or one agency for ads, social and brand work as well as search. The larger Vietnamese agencies below do that.

Choose Saigon Digital if: your buyers are mostly outside Vietnam and you want the work done in English.
How to choose
Ask every agency on your shortlist for the same five things with each result it claims: the engine, the question, the language, the market and the date. Then type the question yourself, in Vietnamese and in English, into a logged-out browser in Vietnam and see who comes back. An agency that reports one “AI visibility” score across every engine and language is hiding the fact that each one answers differently.
Then match the shape of the engagement to your situation. If your buyers search in Vietnamese, make sure the agency writes and measures in Vietnamese. If you already have strong SEO, a GEO add-on may be enough. If you want a fixed budget, look at the project-priced options.
Frequently asked questions
How much does a GEO agency cost in Vietnam?
Among the agencies here that publish prices, combined SEO and GEO packages start at 18,500,000đ a month (Rankpage), GEO projects start from 18 million đồng (SEODO), and GEO Premium starts from 60,000,000đ a month (Hashmeta).

What is dịch vụ GEO?
It is the Vietnamese name for a GEO service: generative engine optimisation, the work of getting your brand named inside the answers AI engines write. GEO has nothing to do with geography. Most of the agencies here also sell classic SEO.
Should my GEO content be in Vietnamese or English?
It depends on who your buyers are and how they ask. When we asked Google AI Mode the same question in both languages from Vietnam, the answers named almost entirely different agencies. If your buyers ask in Vietnamese, you need Vietnamese pages the engine can quote. Regional and export brands usually need both.
Can a Singapore agency do GEO for a Vietnamese business?
Yes. The engines are the same in both countries. What matters is checking answers from a Vietnamese location, in the languages your buyers use, and knowing which Vietnamese sources the engines read for your questions.
