Introduction to Marketing Psychology for SMEs
Marketing psychology helps SMEs understand what customers think and how they act. You don't need a big budget to create effective campaigns. DPS.MEDIA applied to over 5,400 Vietnamese businesses since 2017.
Vietnam has 800,000 SMEs, but only 20% succeed with digital marketing. The secret lies in understanding consumer psychology. This article brings 46 real-world examples in part 1.
Start with the most basic principles. Apply immediately to see the difference in the first week.
Traditional Marketing vs Marketing Psychology
Traditional marketing focuses on direct selling. Marketing psychology evokes emotions and creates latent demand. Vietnamese SMEs often make this mistake when running Facebook Ads.
Example: Instead of “Buy now for 20% off”, use “Only 5 spots left”. Customers feel more urgency. Revenue increased by 35% according to Nielsen Vietnam research.
Understanding psychology helps optimize advertising costs. You save 30-50% budget while having higher conversions.
- Identify customer insights monthly
- Test A/B testing 3 ad variants
- Analyze behavior on Facebook Insights
- If CTR below 2%, then change the emotional title
- Track conversion rate by psychology of each age group
- Optimize landing page according to FOMO principles
Why Vietnamese SMEs Need Marketing Psychology Now
Vietnamese people are strongly influenced by collectivist culture. They buy based on friends, social media trends. Understanding this helps SMEs outperform competitors.
Case study: A cafe SME in Saigon applies social proof. Post story “100 customers check-in today”. Revenue increased 250% on weekends.
Applying psychology is not difficult. Just change the way you write content and posting timing.

11 Cialdini Principles Applied to Digital Marketing
Robert Cialdini identified 6 principles of persuasion (later added Unity). SMEs use effectively on Facebook, TikTok Vietnam. DPS.MEDIA has tested on over 100 campaigns.
Each principle increases conversion rate by 15-40%. Combining them creates a doubling effect. Start with the easiest principle.
1. Scarcity – Create a Sense of Urgency
People fear loss more than they like gain. “Only 3 spots left” is more effective than “50% off”. Apply to SME flash sales.
Real example: Shopee Vietnam uses countdown timer. Click rate increased 67%. SMEs copy this format for landing page.
Don't overuse it or lose credibility. Use at the right time to create real urgency.
- Add countdown timer to every promotion
- Write “Only X spots left” on CTA button
- Limit quantity of hot products
- If stock below 10%, then highlight immediately
- Test position of scarcity element A/B
2. Social Proof – Power of the Crowd
90% Vietnamese people read reviews before buying. Displaying testimonials increases trust 80%. Especially effective for new SMEs.
Case: Mini spa in Hanoi posts “500 5-star customers”. Booking increased 180% in the first month. Use real customer photos.
Combine with specific data. “Over 2,000 SMEs trust and use” creates strong authority.
- Collect first 50+ 5-star reviews
- Display star rating on website
- Post user-generated content weekly
- Tag customers in success stories
- If under 10 reviews, encourage exchange for gifts
- Create Trustpilot/Google review widget
| Type of Social Proof | Effectiveness | Example SMEs |
|---|---|---|
| Customer reviews | +45% conversion | Beauty shop FB |
| Case studies | +60% B2B leads | Digital agency |
| Influencer posts | +120% reach | Fashion brand |
| Live counter | +33% urgency | Ecommerce site |
3. Authority – Build Expertise
Customers trust experts more than ads. SMEs need to prove field knowledge. Use certificates, media mentions.
Example: Restaurant posts “Featured on VTV1”. Customer bookings increase 75%. SMEs follow this format.
Content marketing is the key. Write in-depth posts on fanpage.
4. Liking – Emotional Connection
Buy from people you like. SMEs build approachable brand personality. Vietnamese like humorous, authentic brands.
Vietnam TikTok Trend: Owner appears to talk directly. Interactions increase 300%. Easy to do, low cost.
Find common ground with audience. Ask daily interaction questions.

5. FOMO Effect (Fear of Missing Out)
Young Vietnamese fear missing trends. “Everyone is buying” strongly activates FOMO. Use for Gen Z, Millennials.
Example: Gym SMEs post “Class full, sign up now or miss out”. Memberships sell out in 2 days. Include live class video.
Timing is important: Post 8-10pm most effective.
- Create monthly live flash sales
- Post story “Sold out update”
- Use emoji 🔥⏰ urgency
- If audience 18-25, add trend music
- Retarget cart abandoners with FOMO
- Track FOMO ads separately in dashboard

Shopee/Lazada master this technique. SMEs copy: Price 1.990k → Sale 499k. Conversion increases 92%.
Test multiple anchor levels for the same product.
7. Zeigarnik Effect – Remembering Unfinished Tasks
The brain remembers unfinished tasks more than completed ones. Apply to checkout process. Cart reminders create positive tension.
Email sequence: “Your cart is waiting”. Open rate 45%, recovery 28%. Vietnamese SMEs rarely use it, big opportunity.

| Stage | Zeigarnik Message | Timing |
|---|---|---|
| Cart abandon | “Your cart is waiting for you” | 1h later |
| Form incomplete | “Complete registration to receive gift” | 30m later |
