digitalbinosROI Metrics That Matter Most in Vietnam’s E-commerce Marketing
Vietnam’s e-commerce sector is one of the fastest-growing in Southeast Asia, fueled by increasing internet penetration, mobile adoption, and a young, digital-savvy population. According to Statista, the country’s e-commerce market value is expected to exceed US$39 billion by 2025, with annual growth rates of over 20%.
However, as competition intensifies, measuring Return on Investment (ROI) accurately becomes critical for brands aiming to scale profitably. In this blog, we’ll explore the ROI metrics that matter most in Vietnam’s e-commerce marketing, why they’re important, and how businesses can use them to optimize performance Vietnam-agent.com .
1. Customer Acquisition Cost (CAC)
Why it matters: CAC tells you how much it costs to acquire a new customer through your marketing campaigns. For e-commerce brands in Vietnam, where digital ad spend is rising, tracking CAC ensures you’re not overspending on short-term gains.
How to calculate it:
CAC=Total Marketing and Sales CostsNumber of New Customers Acquired\text{CAC} = \frac{\text{Total Marketing and Sales Costs}}{\text{Number of New Customers Acquired}}
If you’re running Facebook ads in Vietnam (a common tactic given Facebook’s dominance locally), and spending VND 20 million monthly while gaining 1,000 customers, your CAC is VND 20,000.

2. Customer Lifetime Value (CLV or LTV)
Why it matters: This metric estimates the total revenue a customer will generate over the course of their relationship with your brand. CLV helps justify CAC—especially in Vietnam where loyalty is harder to win due to the prevalence of flash sales and aggressive discounting.
How to calculate it:
CLV=Average Order Value×Purchase Frequency×Customer Lifespan\text{CLV} = \text{Average Order Value} \times \text{Purchase Frequency} \times \text{Customer Lifespan}
If your average order is VND 500,000, and the average customer buys three times a year for two years, your CLV is VND 3,000,000.
Optimization tip: Use retargeting and loyalty campaigns on Zalo Ads or Lazada Vietnam to boost frequency and retention.
3. Conversion Rate (CR)
Why it matters: Conversion Rate shows how well your marketing channels or website turn visitors into customers. In Vietnam’s mobile-first market, a slow or poorly localized site can cause sharp drop-offs.
How to calculate it:
Conversion Rate=(Number of ConversionsTotal Visitors)×100\text{Conversion Rate} = \left( \frac{\text{Number of Conversions}}{\text{Total Visitors}} \right) \times 100
A well-optimized product page with local language, payment options like MoMo or ZaloPay, and fast loading speed typically converts better.
Bonus tip: Run A/B tests using Google Optimize or local analytics tools like Beeketing for Vietnam to improve conversion rates.
4. Average Order Value (AOV)
Why it matters: AOV helps determine how much customers typically spend per transaction. It’s a critical metric when assessing ROI because increasing AOV can often be more cost-effective than acquiring new customers.
How to calculate it:
AOV=Total RevenueNumber of Orders\text{AOV} = \frac{\text{Total Revenue}}{\text{Number of Orders}}
Vietnamese consumers often respond well to free shipping thresholds and bundle promotions, making this an excellent lever for improving ROI.
Example: Offering “Free shipping for orders over VND 800,000” can boost AOV while reducing abandonment rates.
5. Return on Ad Spend (ROAS)
Why it matters: ROAS directly measures how effective your ad campaigns are in generating revenue. For e-commerce businesses in Vietnam running Google Shopping, Shopee Ads, or TikTok campaigns, ROAS is a must-track metric.
How to calculate it:
ROAS=Revenue from AdsCost of Ads\text{ROAS} = \frac{\text{Revenue from Ads}}{\text{Cost of Ads}}
A ROAS of 4:1 means you earn VND 4 for every VND 1 spent—generally considered a healthy benchmark depending on the industry.

6. Cart Abandonment Rate
Why it matters: This shows the percentage of users who add items to a cart but don’t complete the purchase—a common issue in Vietnam’s price-sensitive market.
How to calculate it:
Cart Abandonment Rate=(Carts – PurchasesCarts)×100\text{Cart Abandonment Rate} = \left( \frac{\text{Carts – Purchases}}{\text{Carts}} \right) \times 100
High rates can indicate problems with payment gateways, shipping fees, or lack of local trust. Offering localized payment options and live chat support can help reduce friction.
7. Website Bounce Rate
Why it matters: A high bounce rate means visitors leave without interacting with your site. In Vietnam, slow mobile sites or non-Vietnamese content can cause this.
Use tools like Google Analytics or Hotjar to identify drop-off points and optimize accordingly.
8. Social Engagement to Conversion Ratio
Why it matters: Vietnamese users are among the most active on social media in the region. However, social engagement doesn’t always translate to sales. Tracking how many likes and shares lead to purchases can help brands adjust their content strategies.
Platforms like Cốc Cốc Ads allow you to measure click-through rates and engagement performance with Vietnamese audiences.
