Introduction: Why running Facebook Ads in Vietnam is easy to \u201cburn money\u201d?<\/h2>

Facebook remains the leading advertising channel in Vietnam with over 70 million monthly active users. However, many SMEs spend heavily without achieving desired results. According to the We Are Social Digital 2023 report, Facebook advertising costs in Vietnam increased 25% compared to the previous year.<\/p>

1. Ignoring the specifics of Vietnamese user behavior<\/h2>

Misunderstanding the online time of target customers<\/h3>

Many advertisers run ads during international peak hours (8-10 AM) instead of Vietnam hours (7-10 PM). Vietnamese people often browse Facebook after work, especially on weekends. This leads to low CTR and CPA twice as high.<\/p>

Real example: ABC cosmetics campaign ran ads during US hours in March 2023, burned 150 million VND in 7 days for only 200 orders. After switching to 7-11 PM slot, same budget achieved 850 orders.<\/p>

Not taking into account local cultural factors<\/h3>

English copy or Western images not suitable for Vietnamese psychology. Local customers prefer relatable content with community elements. Facebook IQ 2022 report shows ads with local elements increase conversion rate 47% in Southeast Asia.<\/p>

    3. Creative not optimized for Facebook algorithm<\/h2>

    Using single image instead of carousel\/video<\/h3>

    Single image only achieves average CTR 0.91%, while carousel reaches 1.81% and video 2.31% according to the Socialbakers 2023 report. Facebook algorithm prioritizes diverse content, keeping users longer.<\/p>

    Example Shopee VN Q4\/2022: Shifted 701% budget to video ads, increasing ROAS from 2.1x to 5.2x in 45 days.<\/p>
