1. SEONGON

SEONGON suits large Vietnamese brands and state-owned groups that want SEO, Google Ads and AI search from one team in Hanoi and Ho Chi Minh City. Founded in 2012, it says it has worked with over 2,500 medium and large enterprises and run over 900 SEO projects.

Its English homepage names Vietnam Airlines, Viettel and VNPAY among its clients. Two case studies carry hard numbers: a 1,545% rise in SEO conversions for An Hung Architecture, and 263.1% revenue growth for the consumer lender MAFC. SEONGON won a Google Agency Excellence Award in 2024 and is a Google Premier Partner and a Zalo Ads Premier Partner.

Of the four agencies here that publish a headcount, SEONGON's is the largest, at over 120 staff. It also sells courses in SEO, Google Ads and SEO content, and its staff bios cite technical SEO work for Sun World, ShopDunk and 30Shine Shop. Its price page promises 1 to 2 months of results warranty after a contract ends, and quotes 400 million to 700 million VND for real estate projects.

• Best for: Enterprises with budget for a 6 to 9 month project that want SEO and Google Ads from one partner.
• Where it falls short: The price list is only in Vietnamese, and its Clutch profile shows 3 reviews (5.0, read September 2026).
• Pricing: Comprehensive SEO from 300 million VND per project, which SEONGON puts at about 60 million VND a month.

2. TOS (TopOnSeek)

TOS fits enterprise and fintech brands that want Google rankings plus citations in ChatGPT, Gemini and Perplexity answers from a specialist SEO agency. Its ELSA Speak campaign raised organic traffic tenfold and leads threefold, and made the 2023 Global Agency Awards shortlist for Best SEO Campaign.

TOS dates itself to 2016 and lists 85+ employees across two Ho Chi Minh City offices and one in Da Nang. ZaloPay, Timo, Shopee and Unilever appear on its client wall. For ZaloPay, TOS reports keyword rankings at over 130% of the KPI, and a homepage testimonial credits it with lifting monthly organic traffic from 55,000 to 560,000.

Beyond SEO, its menu lists GEO, conversion rate optimization, data intelligence, and web and app development. Paid ads are missing from that menu, which matters if you want search and PPC from one agency:

On Clutch, TOS rates 5.0 from 6 reviews (read September 2026). The profile sets a $10,000 minimum project size and puts 45% of its work in SEO. The TOS site lists a Best Use of Search win in FMCG and a finance SEO shortlist, and offers a free checker that scores a domain's AI visibility across 6 GEO pillars.

• Best for: Banks, fintechs and e-commerce brands that need SEO, GEO and conversion work on the same team.
• Where it falls short: It publishes no prices, and the $10,000 Clutch minimum rules out small budgets.
• Pricing: On request.

3. GTV SEO

GTV SEO works for companies that want an agency to run SEO and then train their own staff to keep it going. CEO Đỗ Anh Việt founded it in 2016 as Growth Team Vision, and its YouTube channel on SEO, AI and automation has 66,000+ subscribers.

The GTV SEO homepage lists 80+ staff, offices in Ho Chi Minh City and Hanoi, 500+ SEO projects and 5,000+ trained students. Its Vinamilk case for 2023 to 2024 reports 583,000+ in traffic growth and 2,453 orders from SEO. For Bamboo Airways in 2019 to 2020, 76% of service keywords reached the top 5.

Its public price table starts at 300 million VND for 8 to 10 months and 150 to 350 keywords. Premium starts at 450 million VND and Enterprise at 700 million VND. Clients pay the first month up front and each later month after KPI sign-off, and GTV trains the client's staff at no charge.

• Best for: Mid-size and large Vietnamese brands that want SEO know-how passed to their own team by the end of the contract.
• Where it falls short: The price list and case studies are in Vietnamese, and we found no Clutch profile for it.
• Pricing: From 300 million VND per 8 to 10 month project, excluding VAT.

4. On Digitals

On Digitals fits foreign brands entering Vietnam or Southeast Asia that want SEO from an English-speaking agency in Ho Chi Minh City. Ducati used its outsourced SEO support for its Vietnamese market entry, and On Digitals reports a 150%+ rise in website visits.

Founder Vincent On studied information technology at Deakin University in Melbourne. On Digitals runs its site in English, Vietnamese, Chinese, Korean and Japanese, with market pages for the US, the UK, Australia, Singapore and Malaysia. Its SEO service page lists keyword research for Colgate-Palmolive's Thai market entry and a 140%+ monthly revenue increase for Passion Wine.

That SEO page now covers answer engine optimization for ChatGPT and Google's AI Overviews. On Digitals sells link building as its own service, so compare that line with what link building costs. The founder's page credits the team with 131 keywords in the top 3 for Bigbike.

Its Clutch profile holds 32 reviews at 5.0 (read September 2026), with projects from $1,000 and hourly rates of $25 to $49. Clutch lists 2019 as the founding year.

• Best for: International brands that need Vietnamese or Thai keyword research and an SEO program run in English.
• Where it falls short: SEO is 40% of its Clutch service mix, next to social, web design and ads, and it publishes no package prices.
• Pricing: On request; Clutch lists a $1,000 minimum project.

5. SEODO

SEODO fits Vietnamese SMEs that want a fixed monthly SEO fee with ranking targets in writing. Beyond the top 10 share in its Standard plan, it also commits 20 to 30% of keywords to the top 5.

SEODO started in Da Nang in 2016 and now keeps its head office on Láng Street in Hanoi, with offices in Da Nang and Ho Chi Minh City. The SEODO homepage lists 70+ staff and says each holds an SEO certificate from Google, HubSpot, Coursera or LinkedIn. One new architecture brand reached 55,000 organic visits and 200 contacts a month.

All three plans carry a price:

• Standard: from 20 million VND a month on a 7 to 9 month contract, with a 1-month warranty.
• Premium: from 50 million VND a month over 9 to 11 months, adding Google Ads support.
• Royalty: from 80 million VND a month for 10 to 12 months.

After the warranty, SEODO charges 5 to 7% of the contract value a month for upkeep.

• Best for: SMEs in Hanoi, Da Nang or Ho Chi Minh City that want a monthly price agreed before the first call.
• Where it falls short: The site is only in Vietnamese, and the committed keyword set is one SEODO proposes.
• Pricing: From 20 million VND a month (Standard), 50 million (Premium) or 80 million (Royalty).

6. Seotal

Seotal is our company, so weigh this entry accordingly. It suits businesses that want one dedicated freelance SEO specialist, including Vietnamese talent, rather than an agency team. Seotal is not a local agency and has no office in Vietnam.

Founded in November 2020, Seotal screens freelancers with a portfolio review, a written SEO test, a live technical interview with a senior SEO lead, an English test and a reference check. Its FAQ says fewer than 5% of applicants join the active pool. Clients get a shortlist of 3 to 5 profiles within 72 hours of a brief.

Seotal's pricing page lists three models: hourly, part-time and full-time. Hourly work costs $15 to $30 an hour with no minimum.

A part-time retainer costs $1,000 to $2,000 a month for 60 to 80 hours, with a 3-month minimum, a free replacement in the first 30 days and a live Looker Studio dashboard. Full-time hires are custom priced, with a 6-month minimum.

For Vietnam, the same page lists monthly rates for an SEO expert from $450 to $800 at junior level to $3,800 to $6,000 at lead level. The country hub covers a Vietnamese SEO specialist and a technical SEO specialist in Vietnam.

• Best for: Startups and SMBs that want a named specialist working set hours inside their own tools.
• Where it falls short: You get one freelancer, not an agency's content, link and technical teams.
• Pricing: $15 to $30 an hour, or $1,000 to $2,000 a month part-time.

7. Omega Digital

Omega Digital fits SMBs and mid-market firms that want a fixed US dollar fee and one channel handled first. About 80% of its clients are companies with $1M to $10M in annual revenue, according to its about page.

Founder and CEO Wes Jackson runs the Ho Chi Minh City agency. He also started the HCMC Digital Marketing Meetup and the HCMC AI Meetup, which have drawn over 1,300 professionals across 12 events. On Clutch, Omega Digital rates 5.0 from 20 reviews (read September 2026), and Clutch gives 2017 as its founding year.

Omega's pricing page opens with a Clarity Audit at $1,000, paid once. Growth Starter covers SEO or organic social for $2,000 in the first month, then $1,000 a month. Growth Engine costs $4,000 a month for two channels, and Full Stack Partner starts at $8,000. Omega bills ad spend, software and hosting on top.

Its SEO case study covers the International School Ho Chi Minh City in 2019. An audit found over 80% of site images above 100 KB, plus a suspicious backlink profile that pointed to negative SEO. After the fixes, organic traffic rose 64%. Inquiries from organic search grew 23% that year.

• Best for: SMBs that want a published price and a first call with the founder before signing.
• Where it falls short: SEO is 17% of its Clutch service focus, and its published SEO case study dates from 2019.
• Pricing: $2,000 for the first month, then $1,000 a month for one channel; audits cost $1,000.

8. SEO Mentors

SEO Mentors fits companies with an in-house SEO team that needs coaching more than outsourcing. For the IT jobs platform ITviec, it mentored the internal team and advised on the CMS and off-page strategy, and organic traffic grew 30% after 6 months.

CEO Đoàn Mậu Hoài founded the company in 2019 as 3HDIGI with two staff, according to its about page. It grew to 7 full-time staff and 10+ collaborators by 2021, and renamed itself SEO Mentors in January 2024. The office is on Lê Lai Street in District 1, and its English homepage counts 50+ projects to date.

Besides full SEO and audits, it sells SEO training for managers, press releases and brand protection, which pushes negative results down the page. Clients named on the site include TopDev, AloBacsi and JobTest. Its Clutch profile shows 5.0 from 2 reviews (read September 2026).

Each plan in the price table runs as a 12-month campaign. Start Plan costs from 25 million VND a month, with a traffic target of +20% a month and 80% of keywords in the top 10. Premium costs from 50 million VND a month for up to 300 keywords, and Dominate has no published price.

• Best for: Startups and platforms with their own SEO staff who want a senior adviser and a written plan.
• Where it falls short: The team is small, and each published plan needs a 12-month commitment.
• Pricing: From 25 million VND a month on a 12-month campaign.

9. BiziBusiness

BiziBusiness fits e-commerce brands selling in the US and Australia that want an offshore SEO team. Dog apparel brand Dr. Woof Apparel went from 500 to 5,000 monthly organic visits in Australia within six months, and passed 6,000 in the US.

CEO and co-founder Colin Melia has 10+ years in digital marketing and, per the BiziBusiness homepage, oversees 70+ clients. Its FAQ credits its Vietnam base for prices "much lower" than US agencies charge. Clutch lists a Ho Chi Minh City headquarters, 2018 as the founding year and 60% of its work in SEO.

Services come as branded lines. BiziSEO covers SEO, YouTube SEO and local SEO, BiziGEO covers generative engine optimization, and BiziWebsites builds Shopify stores. BiziAds runs Google, Meta, TikTok and LinkedIn campaigns, and the site offers a free technical SEO audit and an SEO ROI calculator. The case studies page credits paddle board brand iRocker with five times the organic traffic and 50% more revenue in six months.

On Clutch, BiziBusiness rates 5.0 from 7 reviews (read September 2026), with a $1,000 minimum project and rates of $25 to $49 an hour.

• Best for: Direct-to-consumer brands that want SEO, ads, email and a Shopify build from one English-speaking team.

• Pricing: On request; Clutch lists a $1,000 minimum project.

10. Saigon Digital

Saigon Digital fits international companies that need a new website built and optimized for search by the same team. Founders Nick and Jonas run an agency that rebuilt Ski.com on the Prismic CMS and moved Kenno onto headless HubSpot CMS with React, built to pass Core Web Vitals.

The agency sits at 19 To Huu in Ho Chi Minh City. Its SEO agency page offers multilingual SEO in Vietnamese, English, German, French and Korean, and says most clients see ranking and traffic gains within 3 to 6 months. The team page lists an SEO team leader and two SEO specialists beside the developers.

Other services include AI search optimization, AI workflow automation, HubSpot development, and Google and Meta ads. Its Saigon Baigur case paired Next.js with the Strapi headless CMS. If you only need the technical audit, compare its rates with independent technical SEO experts.

On Clutch, Saigon Digital rates 5.0 from 2 reviews (read September 2026). Clutch lists it as founded in 2021, with 85% of its work in SEO, a $5,000 minimum project and rates of $50 to $99 an hour.

• Best for: Companies moving to Next.js, Prismic, Sanity or HubSpot that want technical SEO built into the rebuild.
• Where it falls short: None of its case studies publishes traffic or ranking numbers, and it is the youngest agency here.
• Pricing: On request; Clutch lists a $5,000 minimum project.

Hiring a Vietnamese SEO specialist instead of an agency

The nine agencies above sell a team on a project or a retainer. For one person on set hours, Seotal matches you with a vetted freelance SEO expert, including specialists in Vietnam. Rates are on our pricing page, and the Vietnam hiring hub covers the local talent pool.

I lead SEO and GEO at Seotal, and we send 3 to 5 screened profiles within 72 hours of a brief. Hire a freelance SEO expert, or first check an agency quote against what SEO outsourcing costs.
