## Purchase Psychology Framework

### Cialdini's 6 Principles of Persuasion

| Principle | Application | E-commerce Example |
|-----------|------------|-------------------|
| Reciprocity | Provide value first | Free samples, coupons, content |
| Commitment | Small commitment -> large commitment | Cart -> wishlist -> purchase |
| Social Proof | Show others' behavior | Reviews, sales volume, "N people viewing" |
| Liking | Empathy, similarity | Models/influencers, stories |
| Authority | Expert endorsement | Certifications, awards, expert recommendations |
| Scarcity | Limited opportunity | Limited quantity, flash sales, deadline approaching |

### Purchase Decision Journey (AIDA)

```
Attention -> Thumbnail, main image, headline
Interest -> Benefit highlights, problem empathy
Desire -> Social proof, comparative advantage, visualization
Action -> CTA, urgency, payment convenience
```

## Detail Page Conversion Structure

### Optimal Section Order

```
1. Hero Area (Above the fold)
   - Main image (5+ images, multiple angles)
   - Product name + core USP (1 line)
   - Price + discount information
   - CTA button (Add to cart / Buy now)
   - Shipping/benefit icons

2. Trust Area
   - Rating + review count + star distribution
   - Certification/award badges

3. Benefits Area
   - Before/After comparison
   - 3-5 key benefits (icon + short description)

4. Detailed Description
   - Usage scenarios (lifestyle imagery)
   - Product specs/ingredients table
   - Size guide

5. Social Proof
   - 3-5 best reviews (photo reviews preferred)
   - Media features/expert recommendations

6. FAQ
   - Top 5 frequently asked questions

7. Cross-sell
   - Frequently bought together
   - Similar product recommendations
```

### CTA Optimization

| Element | Recommended | Avoid |
|---------|------------|-------|
| Copy | "Buy Now", "Add to Cart" | "Submit", "Confirm" |
| Color | Contrasting with page primary color | Similar to background |
| Position | Above the fold + sticky on scroll | Bottom only |
| Size | Thumb-tappable (44px+) | Too small |
| Urgency | "Today only discount", "3 remaining" | Always urgent (erodes trust) |

## Pricing Psychology Strategies

### Price Framing

| Strategy | Method | Example |
|----------|--------|---------|
| Anchoring | Show list price first, then sale price | ~~$39.90~~ -> $29.90 |
| Partitioning | Break into monthly/daily amounts | "Just $0.99 per day" |
| Bundling | Bundle discount | "Buy 3 get 1 free" |
| Decoy | Add a comparison option | S/M/L where M appears optimal |
| Free Shipping | Include shipping in product price | "Free shipping on orders over $30" |

### Price Ending Effects

| Strategy | Best For | Example |
|----------|---------|---------|
| Ending in 9 | Discounts/value pricing | $29.90 |
| Ending in 0 | Premium/luxury | $30.00 |
| Fewer digits | Perceived lower price | $29.90 vs $30.00 |
