What Claude Does vs What You Decide
What This Skill Does
This skill transforms copywriting from a guessing game into a systematic, data-driven process. Instead of staring at a blank page and hoping inspiration strikes, you'll:
- Research first - Find your messages in customer language, not your imagination
- Listen more than write - Let Voice of Customer (VOC) data do the heavy lifting
- Validate before launching - Test copy before committing fully
- Measure everything - Know what's working and why
The result: Copy that converts because it says what customers actually want to hear, in the words they already use.

The 3-Part Process Overview
No phase is optional. Even if a client says "just write," you still need research.
Part 1: Research & Discovery
"If research is not the biggest part of the work, 99% of the time it means you're doing it wrong."
Goal: Find your messages in customer language—don't invent them.

How to Mine VOC Data
What to look for:
- Pain language - How do they describe their problem?
- Desire language - What outcome do they want?
- Objection language - What's stopping them?
- Trigger language - What made them start looking?
- Value language - What benefits matter most?
- Emotional language - How do they feel about all of the above?
How to organize:
- Tag each insight by type (pain, desire, objection, etc.)
- Note the source and frequency
- Identify patterns and repeating themes
- Rank by strength/emotion
Part 2: Writing, Wireframing & Editing
The Writing Setup
Joanna's Split-Screen Method:
- Open research/VOC data on LEFT side of screen
- Open writing document on RIGHT side
- Search VOC data for relevant keywords
- Copy-paste actual customer language
- Refine into copy (don't reinvent)
"You don't sit there and just start writing. Split your screen in two and take what people are saying and put it on the page."
The Writing Process
Step 1: Determine Awareness Stage
Where is your reader starting?
Step 2: Map Your Messaging Hierarchy
What messages need to appear, and in what order?
- Primary Message - The one thing they must understand
- Supporting Messages - Evidence that backs up the primary
- Objection Handlers - Address what's holding them back
- Call to Action - The specific next step
Step 3: Select Your Framework
Step 4: Draft Using VOC
Take raw VOC and transform:
Raw VOC:
"I was so frustrated with spreadsheets. Every month I'd spend 8 hours just reconciling data and I'd still find errors."
Transformed into Copy:
"Tired of losing 8+ hours every month to spreadsheet reconciliation—only to find errors anyway?"
The 7 Sweeps Editing Process
After your first draft, run these sweeps in order:
Clarity is ALWAYS first. Above everything else, copy must be clear.
Wireframing
Create a visual layout showing:
- Where each message block goes
- Image/video placeholders with notes
- CTA placement and copy
- Mobile considerations
Tools: Figma, Balsamiq, Photoshop, or even Google Docs with boxes
Part 3: Validation & Experimentation
"We test to validate and learn."
Goal: Ensure you're putting the best version out before committing.
Validation Methods
A/B Testing When Possible
Test one variable at a time:
- Headlines
- CTAs
- Lead image
- Offer structure
- Social proof placement
Note: You can't A/B test everything. Validation fills the gaps.
Examples
Example 1: SaaS Landing Page Process
Research Phase (Week 1):
- Interviewed 5 customers
- Mined 50 G2 reviews
- Analyzed 10 competitor pages
- Reviewed 20 support tickets
Key VOC Finding:
"I was drowning in Slack notifications. By the time I found the message I needed, I'd lost 20 minutes and my train of thought."
Messaging Hierarchy:
- Primary: "Find any message in seconds, not minutes"
- Supporting: AI-powered search across all channels
- Objection Handler: "Works with your existing Slack—no migration"
- CTA: "Start free trial"
Draft Headline:
"Stop drowning in Slack. Find any message in seconds."
After 7 Sweeps:
"Find any Slack message in 3 seconds. Not 20 minutes." (Added specificity, cut unnecessary words)
Validation:
- 5 Second Test: 85% understood the value prop
- A/B tested against control: +34% signups
Example 2: Email Sequence for Course Launch
VOC from Survey:
"I keep signing up for courses but never finish them. I feel guilty every time I see another one in my inbox."
Email 1 Subject (Problem-Aware):
"That course you never finished? Not your fault."
Email 1 Opening:
"You've bought courses before. Started strong. Then... nothing.
The guilt sits there in your inbox. Every email from that course creator feels like a reminder of another thing you didn't follow through on.
Here's the thing: It's not a willpower problem."
Transformation Notes:
- Used exact phrase "never finish"
- Captured the "guilt" emotion from VOC
- Moved from Problem → Solution setup
