Why does 60% of revenue come from customer referrals?

Reality from the Vietnamese market

SMEs in Vietnam often spend heavily on Facebook and Google Ads. But data from Nielsen Vietnam shows that 60-70% of new customers come from referrals. This saves acquisition costs 5 times more than traditional ads.

Returning customers bring 67% higher profits than new ones. They also refer more friends, creating a natural growth loop. This is the ‘gold’ that many digital marketing agencies are mining.

Are you missing out on this revenue source? Shift your strategy now to optimize marketing ROI.

  • Identify current customer return rate via Google Analytics
  • Calculate acquisition cost versus lifetime value
  • If the referral rate is below 20%, prioritize building a loyalty program
  • Track Net Promoter Score (NPS) quarterly
  • Analyze old customer data to find referral patterns

Outstanding benefits for SME digital marketing

Referral marketing helps SMEs reduce dependency on paid traffic. When the Facebook algorithm changes, revenue is not affected. Referred customers have a conversion rate 4 times higher.

For example, an agency in HCMC applied a referral program. After 6 months, 55% of new leads came from old customers, revenue increased by 240% without increasing the ads budget.

Important insight: Focus on current customers before hunting for new ones. They are the most effective marketing channel.
