Copywriting — Persuasion, Conversion & Brand Voice
Write copy that moves people to action — from landing page headlines to email sequences to product descriptions that sell.
When to Use This Skill
USE when:
- Writing landing pages, sales pages, or product pages
- Crafting email campaigns (launch, nurture, re-engagement)
- Creating product descriptions for stores or marketplaces
- Writing CTAs, taglines, headlines, and ad copy
- Defining or applying brand voice and messaging
DON'T USE when:

Principle 1: The Copy Framework Stack
Choose Your Framework
| Framework | Structure | Best For |
|---|---|---|
| AIDA | Attention → Interest → Desire → Action | Landing pages, sales pages |
| PAS | Problem → Agitate → Solution | Email, blog intros, ads |
| BAB | Before → After → Bridge | Case studies, testimonials |
| 4 Ps | Promise → Picture → Proof → Push | Long-form sales letters |
| FAB | Features → Advantages → Benefits | Product descriptions |
AIDA Applied
## ATTENTION (Headline — stop the scroll)
"Ship your SaaS in a weekend, not a quarter."
## INTEREST (Subhead + opening — hook them deeper)
"The average developer spends 6 weeks on auth, payments, and deployment
before writing a single line of product code."
## DESIRE (Body — make them want it)
"[Product] gives you auth, billing, deployment, and analytics out of
the box. Our customers launch 4x faster — and the last three
ProductHunt #1 Products were built on our stack."
## ACTION (CTA — tell them exactly what to do)
"Start building free → no credit card required"
PAS Applied
## PROBLEM (Name their pain — show you understand)
"You spend more time formatting reports than analyzing data."
## AGITATE (Twist the knife — make the pain vivid)
"Every Monday morning, it's the same: 2 hours copying numbers into
slides, fixing broken charts, chasing people for updates. By the
time the report is ready, the data is already stale."
## SOLUTION (Relief — your product is the answer)
"[Product] generates your weekly report automatically from live data.
One click. Always current. Reclaim your Mondays."
Principle 2: Headlines
Headline Formulas
THE "HOW TO" HEADLINE:
"How to [desirable outcome] without [undesirable requirement]"
→ "How to grow your email list without writing a single blog post"
THE SPECIFIC NUMBER:
"[Number] ways to [achieve goal] in [timeframe]"
→ "7 ways to cut your AWS bill in half this month"
THE QUESTION:
"[Question that implies value]?"
→ "What if your CI pipeline took 30 seconds instead of 30 minutes?"
THE CONTRAST:
"Stop [bad thing]. Start [good thing]."
→ "Stop guessing what users want. Start knowing."
THE TESTIMONIAL LEAD:
"'[Quote from customer about specific result]'"
→ "'We shipped 3x faster after switching' — CTO, Acme Corp"
THE NEGATIVE:
"Don't [common mistake] until you [read/try/see this]"
→ "Don't choose a database until you've read this comparison"
Headline Rules
✓ Specific > vague ("Save 4 hours/week" > "Save time")
✓ Benefit > feature ("Write code faster" > "AI-powered autocomplete")
✓ Concrete > abstract ("10,000 developers" > "Trusted by many")
✓ Short > long (under 12 words for most headlines)
✓ Test 5+ headlines before choosing — your first idea is rarely best
POWER WORDS (use sparingly):
Free, New, Proven, Instant, Easy, Secret, Guaranteed,
Discover, Exclusive, Limited, Simple, Fast, Save, Now
Principle 3: Body Copy
Writing Persuasive Body Copy
RULE 1: LEAD WITH BENEFITS, NOT FEATURES
Feature: "256-bit AES encryption"
Benefit: "Your data is protected by bank-grade security"
Best: "Sleep easy knowing your data has bank-grade encryption (AES-256)"
RULE 2: ONE IDEA PER PARAGRAPH
Short paragraphs (1-3 sentences). White space is your friend.
Online readers scan. They don't read walls of text.
Like this.
RULE 3: USE "YOU" MORE THAN "WE"
✗ "We built an amazing platform that uses AI to..."
✓ "You get instant answers powered by AI that..."
RULE 4: SHOW, DON'T TELL
✗ "Our tool is incredibly fast"
✓ "Average query response: 47ms. That's faster than a blink."
RULE 5: ADDRESS OBJECTIONS
"But what if it doesn't work for my use case?"
→ Handle this before the reader thinks it
Social Proof Patterns
CUSTOMER QUOTE:
"We reduced deployment time from 4 hours to 12 minutes."
— Sarah Chen, VP Engineering at Acme Corp
METRIC PROOF:
"50,000+ developers. 99.99% uptime. 4.8★ on G2."
LOGO BAR:
[Company logos of recognizable customers]
CASE STUDY SNIPPET:
"Acme Corp cut their infrastructure costs by 62% in the first
quarter after migrating to [Product]. Read the full story →"
AUTHORITY:
"Featured in TechCrunch, Wired, and The Verge"
"Winner of the 2025 DevTools Award"
Principle 4: Calls to Action (CTAs)
CTA Hierarchy
PRIMARY CTA (one per page — the main conversion):
Style: Large button, high contrast, above the fold AND at the bottom
Copy: Specific action + value
✓ "Start building free"
✓ "Get your report in 60 seconds"
✓ "Try it free — no credit card"
✗ "Submit"
✗ "Click here"
✗ "Learn more" (for primary CTA)
SECONDARY CTA (lower commitment alternative):
Style: Text link or ghost button
Copy: "See a demo", "View pricing", "Read the docs"
→ For visitors not ready to commit to the primary action
MICRO CTA (within content):
Inline text links: "See how Acme Corp saved $2M →"
→ Keeps engagement without interrupting flow
CTA Button Copy Formula
[Action Verb] + [What They Get] + [Urgency/Qualifier]
GOOD:
"Start your free trial"
"Download the 2026 report"
"Book a 15-minute demo"
"Get instant access"
"Create your first project"
GREAT (adds specificity or value):
"Start building in 2 minutes — free"
"See your savings estimate"
"Join 10,000+ developers"
"Generate your report now"
Principle 5: Email Copy
Email Campaign Templates
LAUNCH EMAIL:
Subject: [Product news] + [specific benefit/number]
Body structure:
Line 1: The news (what's new)
Line 2-3: Why it matters to THEM
Line 4-5: Key features (bullet points)
CTA: Try it / Learn more
P.S.: Urgency or bonus
NURTURE EMAIL:
Subject: [Question] or [Helpful tip]
Body structure:
Line 1: Acknowledge their situation
Line 2-4: Teach something valuable (no selling)
Line 5: Soft bridge to product
CTA: Optional, low-pressure
RE-ENGAGEMENT EMAIL:
Subject: "We miss you" or "Things have changed"
Body structure:
Line 1: Acknowledge absence without guilt
Line 2-3: What's new since they left (specific features)
CTA: "Come back and see what's new"
Unsubscribe: Prominent and respectful
Email Subject Line Rules
✓ Under 50 characters (mobile preview)
✓ Specific > clever ("Your report is ready" > "You won't believe this")
✓ Personalization if genuine ("[Name], your usage report")
✓ Create curiosity gap WITHOUT clickbait
✓ Test 2-3 subject lines per send (A/B test)
✗ ALL CAPS
✗ Excessive punctuation!!!
✗ Misleading content (kills trust permanently)
✗ "Newsletter" or "Update" (boring, gets archived)
✗ Spam trigger words overuse (free, act now, limited time)
Principle 6: Product Descriptions
E-commerce Product Copy Template
## [Product Name]
**[One-line value proposition]**
[2-3 sentence description covering: what it is, who it's for,
and the key benefit]
### Key Features
- **[Feature]** — [Benefit to the buyer]
- **[Feature]** — [Benefit to the buyer]
- **[Feature]** — [Benefit to the buyer]
### Specifications
| Spec | Detail |
|------|--------|
| [Dimension] | [Value] |
| [Material] | [Value] |
| [Compatibility] | [Value] |
### What's Included
- [Item 1]
- [Item 2]
- [Item 3]
SaaS Product Copy
## [Feature/Plan Name]
**[Headline benefit — what they can DO, not what it IS]**
[1-2 sentences expanding on the benefit with specifics]
✓ [Included capability 1]
✓ [Included capability 2]
✓ [Included capability 3]
✓ [Included capability 4]
[Primary CTA button]
"[Customer quote about this specific feature]"
— [Name], [Role] at [Company]
Output
Save copy to the appropriate deliverable format:
- Landing pages:
copy/landing-[page-name].md - Emails:
copy/email-[campaign]-[sequence-number].md - Product descriptions:
copy/product-[name].md
Guidelines
- Benefits over features, always — the customer doesn't care how it works, they care what it does for them
- Write like you talk — then edit for clarity. Robotic copy doesn't convert.
- Specificity is persuasion — "4.8 stars from 2,300 reviews" beats "highly rated"
- Every piece of copy needs ONE primary CTA — don't give readers 5 choices
- Test everything — headlines, CTAs, subject lines. Your intuition is wrong 40% of the time.
- Use
/humanizerto strip AI-generated patterns from drafted copy - Use
/style-guideto maintain brand voice consistency - Use
/technical-writingwhen copy needs to also educate (product docs that sell)
