Untangle Your Sales From Spaghetti Code With The 5 Best SEM Agencies in Vietnam
You have the budget and the product, yet the leads remain elusive. The problem often lies deeper than your ad copy.
In the industry, “spaghetti code” refers to websites built with such tangled, unstructured programming that tracking a conversion or optimizing a landing page becomes nearly impossible. For e‑commerce brands and local services, this invisible disorder can slow site speed and make it much harder to measure returns accurately.
Many agencies simply run ads over these cracks, wasting your spend on a broken system.
We looked for the SEM agencies in Vietnam that repair the foundation first. These partners untangle the mess, rebuilding your site’s architecture so your paid search campaigns can finally scale.
How much does SEM cost in Vietnam?
Pricing here remains accessible compared to Singapore or the US, but the quality of management varies heavily by tier.
A standard monthly retainer typically lands between 15,000,000 VND and 50,000,000 VND for reliable service.
If you run a pure PPC campaign, expect management fees to sit between 10% and 20% of your total ad spend.
Smaller budgets (under 25,000,000 VND/month) often incur a fixed minimum fee to cover agency time.
For specialized strategy, hourly consultations usually range from 750,000 VND to 1,500,000 VND.
1. On Digitals
Website: https://ondigitals.com/
Address: 7th floor, 75 Ho Hao Hon, Co Giang Ward, District 1, Ho Chi Minh City
Contact: 0906 648 177
Schedule: Mon-Fri 9:00 AM – 6:00 PM
On Digitals operates as a gateway for international companies entering the Vietnamese market. Rather than simply managing bids, they construct a creative ecosystem where technical performance meets visual design.
Their teams build landing pages that capture attention through high-quality imagery while backend specialists ensure the code converts traffic efficiently.
This approach serves brands that need their SEM strategy to visually match their premium positioning.
Their boutique focus prioritizes quality, which can push pricing higher than the local average for early-stage startups. The team brings fresh energy to campaigns, often favoring innovative ideas over rigid corporate structures.
Companies seeking a polished brand image will see the value immediately.
However, if your goal is volume-based, cheap clicks without regard for aesthetics, their detailed process might provide more than you need.
2. Prodima
Website: https://prodima.vn/en/
Address: 126 Nguyen Thi Minh Khai, Phuong 6, Quan 3, Thanh Pho Ho Chi Minh
Contact: 0968 900 690 and [email protected]
Schedule: Mon-Fri 9:00 AM – 6:00 PM
Prodima operates less like an outsourced vendor and more like a senior consultancy team.
Leadership remains directly involved in daily strategy, with Ben, the founder, often personally reviewing accounts to ensure transparency.
They adhere strictly to sustainable, “white-hat” tactics, avoiding the cheap shortcuts that might spike rankings temporarily but risk long-term penalties.
During consultations, they frequently advise clients on where not to spend money, prioritizing budget efficiency over upsells.
This high-touch consultancy model naturally limits their client intake. They avoid churning out hundreds of low-budget accounts, so businesses looking for instant, low-quality volume may find a better fit elsewhere.
Prodima serves companies seeking a long-term partner who explains the reasoning behind every data point and strategic shift.

I couldn’t be more happy with Prodima and strongly recommend them.
I am an American lawyer and brand consultant. i have been in the Internet business for over twenty years. I have dealt with many developers on my projects, and I have never truly had a positive experience. Until now.
II have been working with Ben’s company for nearly a year on a very important and complicated project. He has been responsive and eager to help and guide us through the process. He and his team are serious professionals and eager to serve. I couldn’t be more happy with Prodima and strongly recommend them.

3. Go Media
Website: https://gonetwork.vn/
Address: Tầng 7, 51 Xô Viết Nghệ Tĩnh, Hòa Cường Nam, Đà Nẵng
Contact: 0833 336 851 | 0398 050 837 | [email protected]
Schedule: Contact Office For Availability
While many large agencies cluster in Ho Chi Minh City or Hanoi, Go Media commands the central region from Da Nang.
What’s interesting about them is how they possess a sharp intuition for the local SME landscape, executing campaigns that resonate deeply with domestic consumers.
Their teams understand the nuances of the central Vietnamese dialect and culture, making them a strong choice for businesses targeting this specific demographic.
By operating out of Da Nang, they also maintain lower overheads, allowing them to offer competitive fees without sacrificing execution speed.
Their focus on the domestic market means their primary communication style and website is in Vietnamese. Expat owners without local language skills might face a slight communication barrier.
But for targeting local consumers, their approach is direct and effective, bypassing the generic strategies often used by more globally-minded firms.
Great support in communicating and completing the work on schedule.
Go Media’s marketing service was effective when I implemented it right from the first month. I also thank Minh, Thien, and Nhon for their great support in communicating and completing the work on schedule.

4. AJ Marketing Vietnam
Website: https://www.ajmarketing.io/
Address: 41A Ly Thai To Street, Hanoi
Contact: [email protected]
Schedule: 24/7 Support, Standard Business Hours on Weekdays
AJ Marketing scales campaigns not just within Vietnam, but across the entire Asia-Pacific region. They integrate SEM with influencer marketing to create a “full-funnel” effect: influencers generate initial interest and buzz, while targeted search ads capture the resulting traffic.
This strategy suits lifestyle, fashion, and tech brands that require loud, coordinated launches rather than silent background optimization.
On top of that, their network spans multiple countries, providing them with a broad perspective on regional trends that single-market agencies often miss.
This extensive scope can prove excessive for simple local service businesses.
A company needing basic Google Ads management might find AJ Marketing’s regional infrastructure and influencer focus too complex for their specific needs.
Nevertheless, they deliver their best work for brands ready to coordinate heavy activity across multiple channels simultaneously.
5. MONA.Media
Website: https://mona.media/
Address: 1073/23 Cách Mạng Tháng Tám, phường Tân Sơn Nhất, Tân Bình, Thành phố Hồ Chí Minh
Contact: 1900 636 648 (Hotline) | [email protected]
Schedule: 24/7 Support, Standard Business Hours on Weekdays
MONA.Media leverages a strong background in web development to solve marketing problems at the source. They understand the code behind SEO, allowing them to fix technical foundations that other agencies might overlook.
If a website is technically broken, slow, or suffering from “spaghetti code,” its developers rebuild the architecture to ensure ads actually lead to conversions. This technical capability sets them apart from pure marketing agencies that lack the manpower to restructure a failing site.
As a high-volume agency, the client experience differs from that of a boutique firm.
You gain access to significant technical muscle and diverse specialists, but the process can feel industrial. Communication may pass between different account managers rather than a single point of contact.
You hire them for their ability to handle complex site fixes and scale, rather than for a personalized, intimate service relationship.
Thank you very much!
Mona Media really impressed me with the SEO service. The team is professional, always supports promptly and helps our website to be on top of Google. It is a pleasure to cooperate and will continue to accompany Mona Media in the future! Thank you very much!
