Introduction: Why choose a reputable online advertising agency?
Vietnam's digital advertising market grows 16% annually according to the eMarketer 2024 report. SMEs often struggle with self-running ads due to lack of optimization experience. Choosing a reputable agency helps save costs and increase ROI effectively.
This article analyzes 15 online advertising companies based on criteria of transparency, measurable results, and real customer feedback. You will learn an evaluation framework to make decisions suitable for your business needs.
Current state of the online advertising market 2024
90% of Vietnamese businesses use Facebook Ads and Google Ads according to the WeAreSocial 2024 survey. However, only 35% achieve positive ROI due to choosing the wrong partner. Reputable agencies help overcome this through data-driven strategies.
Many SMEs report wasting 40-60% of ad budgets due to lack of accurate tracking. This emphasizes the need for partners with real-world experience from 2017 like at DPS.MEDIA.

Benefits of partnering with a professional agency
Agencies help optimize CPC/CPM costs 25-30% lower than self-running. They provide realtime reports and continuous A/B testing. This is especially important for SMEs with limited budgets under 100 million/month.
- Evaluate your business's current budget
- Define specific KPIs (leads, sales, traffic)
- Check real portfolio 3-5 similar case studies
- Compare quotes with industry benchmarks (3-7% of ad budget)
- If remarketing is needed, prioritize agencies experienced with Google Tag Manager
Criteria for evaluating reputable online advertising companies
Choose an agency not just based on low price but consider 5 core criteria: industry experience, tracking tools, expert team, transparent reporting, and scalability. This criteria is built from experience serving 5,400 customers at DPS.MEDIA since 2017.
1. Real-world experience and transparent case studies
Reputable agencies always publicly share case studies with specific data: timeframe, invested budget, measurable results. For example, Company A increased 320% revenue for fashion ecommerce in 3 months with a 250 million budget, but faced scaling limitations when traffic exceeded 50k/day.
Avoid agencies that only boast screenshots of vanity metrics like reach/likes. Request data exports from Google Analytics or Facebook Business Manager to verify.
- Check at least 3 similar industry case studies
- Verify data via third-party tools like SimilarWeb
- Evaluate timeframe (minimum 90 days to see patterns)
- If an agency promises 500% ROI in the first week, be wary of scam signs
2. Tracking tools and real-time data reporting
Professional agencies use Google Tag Manager, Facebook Pixel, Google Analytics 4 with custom events tracking. They provide daily updated Looker Studio dashboards instead of monthly Excel reports.
Common issue: 70% of small agencies fail to set up correct attribution models, leading to 20-40% inaccurate reports. Check by requesting a dashboard demo before signing the contract.
| Criteria | Basic Agency | Professional Agency |
|---|---|---|
| Tracking tools | Basic Facebook Pixel | GA4 + GTM + CAPI + Looker |
| Frequency Report | Monthly Excel | Realtime dashboard |
| Attribution model | Last click | Data-driven/Linear |
| Custom events | No | 20+ events tracking |
| Advantages | Cheap price | High accuracy |
| Disadvantages | Large data discrepancy | High setup cost |
3. Professional team and workflow
A good agency has a clearly assigned team: Account Manager, Media Buyer, Data Analyst, Creative team. Each account is assigned at least 2-3 people instead of 1 multitasking freelancer.
Based on DPS.MEDIA experience, a 7-step process (Audit – Strategy – Creative – Launch – Optimize – Scale – Report) helps increase efficiency by 45%. Check by asking about specific SOPs for your industry.

Comparison framework and evaluation of the most suitable agency
Evaluation matrix based on business needs
| Main needs | Recommended agency | Reason for choosing | Risks to note |
|---|---|---|---|
| Facebook Lead Gen | GCO Ads, DPS.MEDIA | Low CPL 20-40k | Low Quality score |
| Google Shopping | CleverAds, AdsPlus | ROAS 4-6x | High setup cost |
| TikTok Commerce | Growth Ads, MarketingWorks | GMV increases rapidly | Algorithm changes |
| Multi-platform SMEs | DPS.MEDIA, Sapo | Flexible budget | Need to manage multiple channels |
The above matrix is based on benchmarks from 120 campaigns in 2023-2024. Select based on specific industry and budget rather than big brands.
- Determine 3 main KPIs (ROAS, CPL, CAC)
- Allocate test budget 30/70 (test/scale)
- Set milestone reviews every 14 days
- Check contract: clear exit clause
- If ROAS below 2.5x after 30 days, request free audit
Real case study: Choosing the right agency
Company C (spa chain, TP.HCM) test 3 agency: Agency X promised ROI 10x but only achieved 1.8x after 45 days. Switched to DPS.MEDIA, applied full funnel strategy, achieved ROAS 3.9x in 90 days with 180 million budget. Lesson: Prioritize data transparency over promises.

Important notes when working with advertising agency
Common mistakes SMEs often make
Mistake #1: Choosing the cheapest agency instead of the highest ROI. Result: wasted 60% budget in early stage. Always test minimum 30 days with 20-30% budget.
Mistake #2: Not checking traffic quality. Many agencies run poor quality traffic (bot, bounce rate 80%). Require detailed GA4 report source/medium.
Mistake #3: Skipping creative testing. 70% ad effectiveness comes from visual/copy. Good agency runs 10-15 variants/week.
Strategy to optimize agency collaboration costs
Hybrid model: 50% fixed fee + 50% performance bonus (ROAS target). Save 25% costs compared to pure performance agency. Set max cap 12% ad budget.
- Negotiate milestone payment: 30-40-30%
- Require detailed breakdown: management fee vs ad spend
- Test A/B agency: run with the same campaign for 2 weeks
| Payment model | Advantages | Disadvantages | Appropriate |
|---|---|---|---|
| Fixed fee (7-12%) | Predictable costs | Agency lacks motivation | Brand awareness |
| Performance (% revenue) | Align incentive | Attribution dispute | Ecommerce |
| Hybrid | Balance risks | Complex contract | Multi-industry SMEs |
