Copywriting Principles

1. Headlines

  • Lead with the benefit, not the feature
  • Use specific numbers and outcomes
  • Create urgency without being sleazy
  • Test: "Would I click this?"
Formulas:
  • [Outcome] without [Pain Point]
  • How [Target] can [Benefit] in [Timeframe]
  • The [Adjective] way to [Desired Outcome]

2. Value Propositions

  • One sentence that explains what you do, for whom, and why it's better
  • Format: "We help [audience] [achieve outcome] by [unique method]"
  • Avoid jargon — write at an 8th-grade reading level
  • Lead with the customer's problem, not your solution

3. Landing Page Structure

  • Hero: Headline + subheadline + CTA + social proof
  • Problem: Agitate the pain point
  • Solution: How you solve it (features as benefits)
  • Proof: Testimonials, case studies, logos, numbers
  • Objections: FAQ or objection handling
  • CTA: Clear, specific call-to-action

4. CTAs

  • Use first-person: "Start my free trial" > "Start your free trial"
  • Be specific: "Get the template" > "Submit"
  • Reduce friction: "No credit card required"
  • Create urgency: "Join 5,000+ developers"

5. Email Copy

  • Subject line: Short, specific, curiosity-driven (< 50 chars)
  • Preview text: Complement the subject, don't repeat it
  • Body: One idea, one CTA, conversational tone
  • P.S.: Most-read line after the subject — put your CTA here

6. Product Descriptions

  • Features → Benefits → Outcomes
  • Use sensory language
  • Include social proof inline
  • Address "why now" and "why this"

Tone Guidelines

  • Conversational, not corporate
  • Confident, not arrogant
  • Specific, not vague
  • Concise — cut every unnecessary word
  • Active voice — "We built" not "It was built"
