Product Information Extraction

Script Usage

python3 scripts/extract_product.py <url>

Extracted fields:

  • Product name
  • Price/value proposition
  • Key features (3-5)

Content Generation Workflow

Step 1: Analyze Product & Audience

PRODUCT → [What is it? What problem does it solve?]
  |
  ├── TARGET AUDIENCE → [Who needs this? Why?]
  |
  ├── BRAND TONE → [Luxury? Playful? Minimal? Bold?]
  |
  └── PLATFORM FIT → [Feed post, Story, Reel, Carousel?]

Key Questions:

  • What emotion should the user feel?
  • What's the "scroll-stopping" moment?
  • What's the post-purchase transformation?

Step 2: Choose Content Format

Feed Post (Single Image)

  • Best for: Product showcases, announcements
  • Visual: High-quality product shot, clean background
  • Caption: Punchy hook + benefits + CTA

Carousel (Swipe-able)

  • Best for: Features, tutorials, transformations
  • Structure: 5-10 slides
    1. Hook slide 2-4. Feature/benefit slides
    2. CTA slide

Story (15-60 sec)

  • Best for: Flash sales, polls, Q&A, behind-scenes
  • Elements: Interactive stickers, tap-through links

Reel (15-90 sec video)

  • Best for: Demos, unboxing, transformations
  • Hook: First 1 second critical
  • Music: Trending audio boost

Step 3: Generate Content Package

Output format (see templates/OUTPUT_TEMPLATE.md):

## Instagram Content Package

### Post Type: [Feed/Carousel/Story/Reel]

### Image/Video Brief
[Visual direction + composition]

### Caption
[Hook + Body + CTA]

### Hashtags
[30 optimized hashtags]

### Posting Strategy
[Time, frequency, cross-post suggestions]

Instagram Style Guidelines

Visual Principles

  1. Consistency First

    • Cohesive color palette (3-5 colors max)
    • Consistent filter/preset
    • Recognizable brand aesthetic
  2. Quality Over Quantity

    • High-resolution images (1080x1080 or 1080x1350)
    • Good lighting (natural preferred)
    • Clean composition (rule of thirds)
  3. Native Feel

    • Avoid over-polished, stock-looking content
    • Embrace authenticity
    • Show real people/products

Caption Best Practices

✅ DO:

  • Start with a hook (question, bold statement, emotion)
  • Write conversationally (like talking to a friend)
  • Use line breaks for readability
  • Include clear CTA
  • Add 3-5 relevant hashtags

❌ DON'T:

  • Write paragraphs longer than 3 lines
  • Use excessive emojis (1-3 max)
  • Overuse hashtags (30 max, quality > quantity)
  • Sound robotic or overly promotional
  • Include "link in bio" more than once

Engagement Triggers

Embed these in content:

• Questions: "Which color would you choose?"
• Opinions: "Yes or No?"
• Saves: "Save this for later"
• Shares: "Tag someone who needs this"
• CTAs: "Link in bio to shop"

Content Templates

Template 1: Problem-Solution

Hook: Tired of [problem]?
Body: Meet [product]. It [benefit 1], [benefit 2], and [benefit 3].
CTA: Shop now → link in bio

Template 2: Transformation

Hook: Before → After
Body: How [product] transformed [situation].
CTA: See the difference → link in bio

Template 3: Social Proof

Hook: ⭐⭐⭐⭐⭐ "Review quote"
Body: Join [number]+ happy customers.
CTA: Try it risk-free → link in bio

Template 4: Educational

Hook: 5 things you didn't know about [product/category]

CTA: Save this post + follow for more

Template 5: Limited Time

Hook: 🚨 Only [number] left!
Body: [Product] at [price] for [timeframe].
CTA: Don't miss out → link in bio

Advanced: Multi-Post Series

For product launches or campaigns, create 3-5 post series:

Series Structure

  1. Teaser (2-3 days before)

    • Build anticipation
    • "Something big coming"
  2. Launch (Day 1)

    • Product reveal
    • Key features
  3. Deep Dive (Day 2-3)

    • Benefits, use cases
    • Social proof
  4. Urgency (Day 4-5)

    • Limited availability
    • Last chance
