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 their ad budget due to a lack of accurate tracking. This highlights the need for experienced partners with real-world expertise since 2017 like DPS.MEDIA.

Criteria for evaluating reputable online advertising companies

View servicesOverall Media ServicesView servicesWebsite Design ServicesView servicesGraphic Design ServicesView servicesOverall SEO ServicesView servicesE-commerce ServicesView servicesFanpage Management ServicesView servicesGOV Registration ServicesView servicesSeeding ServicesView […]

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.

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's experience, the 7-step process (Audit – Strategy – Creative – Launch – Optimize – Scale – Report) helps increase performance 45%. Check by asking for specific SOP for your industry.

Comparison framework and evaluation of the most suitable agency

Evaluation matrix based on business needs

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 1: Ignoring creative testing. 70% of ad effectiveness comes from visuals/copy. A good agency runs 10-15 variants per 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
• A/B test agency: run the same campaign for 2 weeks
