Copywriting
Copywriting is the craft of writing words that persuade people to take action -
buy, sign up, click, subscribe, or believe. Unlike content writing (which informs),
copywriting converts. Every word earns its place. The best copy feels effortless to
read because enormous effort went into writing it. This skill gives an agent the
frameworks, formulas, and judgment to produce headlines, landing pages, CTAs, value
propositions, email subject lines, and product descriptions that actually work.
When to use this skill
Trigger this skill when the user:
Asks to write or improve a headline, title, or hook
Needs landing page copy, above-the-fold text, or hero sections
Wants to write or optimize a call-to-action (CTA)
Asks for email subject lines or preview text
Needs a value proposition or positioning statement
Wants to apply AIDA, PAS, BAB, or other persuasion frameworks
Asks to write product descriptions that sell
Wants to A/B test copy and needs variant ideas
Asks for "compelling," "persuasive," or "converting" copy
Do NOT trigger this skill for:
Long-form editorial or journalistic content (informing, not converting)
Technical documentation or developer-facing copy where clarity trumps persuasion
Key principles
Clarity over cleverness - If a reader has to think about what you mean,
you've lost them. Plain language outperforms clever wordplay in almost every A/B
test. Say the obvious thing, clearly.
Benefits over features - Features describe the product. Benefits describe
what the customer gains. Never lead with a feature. Translate every feature into
the outcome it produces for the buyer.
One CTA per piece - Multiple calls to action dilute attention and reduce
conversions. Every piece of copy has one job. One desired action. Everything
else is noise.
Write for scanners, then readers - Most visitors scan before they read.
Structure copy so the headline + subheads + CTAs tell the complete story.
Readers who want detail will find it in the body.
Test everything - Copy intuition improves with data. Treat every headline
as a hypothesis. A/B test subject lines, CTAs, and hero copy. Small wording
changes routinely shift conversion rates by 20-40%.
Core concepts
Persuasion frameworks
Three battle-tested structures cover 90% of copywriting situations:
AIDA (Attention - Interest - Desire - Action)
The classic funnel. Hook with attention, build interest with relevance, create
desire by amplifying the benefit, then drive action with a clear CTA. Best for
long-form sales pages and email sequences.
PAS (Problem - Agitate - Solve)
Lead with the reader's pain, twist the knife by amplifying consequences, then
position your product as the solution. Especially effective for cold audiences who
don't yet know they have a problem.
BAB (Before - After - Bridge)
Paint the reader's current frustrating situation (before), describe the ideal
transformed state (after), then present your product as the bridge. Works well for
testimonials, case studies, and social ads.
Voice of customer (VoC) research
The most powerful copy uses the customer's own words. Before writing, collect:
Exact phrases from support tickets and sales call transcripts
Amazon/G2/Trustpilot reviews for the product category
Reddit/forum threads where the target audience describes their problem
Survey responses, especially to "What almost stopped you from buying?"
Mirror this language verbatim in headlines and body copy. It creates instant
recognition: "they're talking about me."
Power words
Words that reliably increase emotional engagement and clicks:
Category
Examples
Urgency
Now, Today, Instantly, Before it's gone
Exclusivity
Only, Private, Members-only, Invitation
Curiosity
Secret, Hidden, Surprising, What most people miss
Credibility
Proven, Backed by, Trusted by, Certified
Ease
Simple, Effortless, One-click, Without the hassle
Benefit
Free, Save, Boost, Double, Eliminate
Use sparingly. Overuse makes copy feel like spam.
Social proof
Proof reduces skepticism. Layer it throughout copy:
Numbers - "14,000 teams use this" beats "used by teams worldwide"
Named testimonials - Full name + company + photo outperforms anonymous quotes
Results-based - "Reduced churn by 31%" beats "great product"
Logos - Well-known customer logos do the work of a thousand words
Press mentions - "As seen in..." for trust with new audiences
Common tasks
Write headlines
A headline's only job is to earn the next line. Use these 10 formula templates:
How-to - "How to [achieve desired outcome] without [common obstacle]"
"How to Write Emails People Actually Open Without Sounding Desperate"
Number list - "[Number] [things] that [outcome]"
"7 Landing Page Mistakes Killing Your Conversions"
The secret - "The [unusual/counterintuitive] way to [desired outcome]"
"The Counterintuitive Reason Your Freemium Users Never Convert"
Question - "[Question that implies reader has the problem]"
"Still Paying Full Price for Software Nobody Uses?"
Direct benefit - "[Do X] and [get Y]"
"Schedule Once and Let the System Handle All Follow-ups"
Before/After - "From [undesirable state] to [desirable state] in [timeframe]"
"From Spreadsheet Chaos to Automated Reports in 15 Minutes"
Social proof hook - "How [customer type] [achieved result] with [product]"
"How a 3-Person Agency Closed $2M Using Cold Email Templates"
Warning - "Don't [do X] until you [read/know/try Y]"
"Don't Launch Your Landing Page Until You Fix These 5 Copy Errors"
Fascination - "[Number] [surprising things] about [familiar topic]"
"9 Things Your Bounce Rate Is Actually Telling You"
Challenge - "What if you could [outcome] without [sacrifice]?"
"What if You Could Double Response Rates Without Writing More Emails?"
Headline checklist: Is the benefit specific? Is the audience implied? Does it
create curiosity or urgency? Is it under 12 words? Could it stand alone?
Write landing page copy
Structure every landing page using this section-by-section framework:
1. Hero section (above the fold)
Headline: primary benefit or transformation (use a formula above)
Subheadline: one sentence clarifying who it's for and how
CTA: verb + specific outcome ("Start Free Trial" not "Submit")
Optional: social proof hook ("Join 14,000 teams...")
2. Problem section
Name the pain clearly, using VoC language
Agitate: what's the cost of not solving it?
Transition: "There's a better way."
3. Solution section
Introduce the product as the logical answer to the pain
Three core benefits (not features) with one supporting sentence each
Show, don't tell: screenshots, demo GIFs, or short video
4. Features section (benefits-led)
Lead with the outcome ("Never lose a lead again"), then the feature beneath it
Limit to 3-6 features - more creates fatigue
5. Social proof section
Two to three testimonials with specific, result-oriented quotes
Customer logos if available
Case study summary with before/after numbers
6. Objection handling (FAQ or dedicated section)
Address the top 3-5 objections from sales calls
Write each answer as a mini persuasion piece, not just a fact
7. Final CTA section
Restate the primary benefit
Repeat the CTA with slightly different framing from the hero
Add urgency or de-risk with a guarantee if available
Craft CTAs that convert
The CTA is the moment of conversion. Apply these rules:
Use first person - "Start My Free Trial" outperforms "Start Your Free Trial"
by 90% in most A/B tests (ownership effect)
Be specific - "Download the 2024 Report" beats "Download Now"
Reduce friction language - "See How It Works" is lower commitment than "Buy"
Add micro-copy beneath - "No credit card required. Cancel anytime."
eliminates the risk objection right at the decision point
Match CTA to page temperature - Cold traffic: "See a Demo." Warm: "Start Free Trial." Hot: "Get Instant Access."
Funnel stage
Low-friction CTA examples
Awareness
"See How It Works", "Watch the Demo"
Consideration
"Start Free Trial", "Get the Guide"
Decision
"Get Instant Access", "Claim My Spot"
Write value propositions
A value proposition answers: "Why should I buy from you, not your competitor?"
Template: [Product] helps [target customer] [achieve outcome] by [differentiating mechanism] so they can [deeper benefit].
Examples:
"Loom helps remote teams communicate faster by replacing long email threads with instant screen recordings so they can move projects forward without another meeting."
"Superhuman helps founders reach inbox zero by combining keyboard shortcuts and AI triage so they spend under 30 minutes on email each day."
Test your value prop against this checklist:
Is the customer and their job-to-be-done clear?
Is the outcome specific and measurable?
Is there a mechanism that distinguishes you from alternatives?
Would this resonate with VoC language from real customers?
Write email subject lines
Subject lines determine 47% of whether an email gets opened. Apply these formulas:
Avoid ALL CAPS and excessive punctuation (spam signals)
Match the tone of what's inside or people feel tricked
Test preview text - it's a second headline
Write product descriptions
Product descriptions must do two things: help the customer picture ownership, and
pre-empt the objection "but does it work for someone like me?"
Structure:
Lead line - The single most compelling benefit, in one sentence
Sensory or outcome detail - Help the reader feel or visualize the result
Feature list - Bulleted, brief, benefits-first
Social proof - One inline stat or quote
CTA - Specific to the product
Bad: "Premium noise-cancelling headphones with 30-hour battery life."
Good: "Silence your open office and stay in flow for 30 hours straight. Adaptive ANC
adjusts to your environment in real time - no more manually tweaking settings when
you move from desk to commute. Rated #1 by Wirecutter for three consecutive years."
A/B test copy effectively
A/B testing copy without structure produces noise. Follow this process:
One variable at a time - Headline OR CTA OR hero image, never all three
Set a hypothesis - "Changing the CTA from 'Get Started' to 'Start My Free
Trial' will increase clicks because it implies ownership and specificity"
Define the metric first - Click-through rate, conversion rate, or revenue
Run to statistical significance - Minimum 100 conversions per variant;
use a significance calculator before calling a winner
Document learnings - Winning insights compound. Keep a swipe file of what
works for your audience
Iterate, don't pivot - If variant B wins, make it the control and test
variant C. Small improvements compound over time.
For subject line testing: 20% to variant A, 20% to variant B, 60% held for the winner (send within 4 hours).
Anti-patterns
Anti-pattern
Why it fails
Fix
Feature-first copy
Readers don't care about features, they care about their life after buying
Lead with the outcome; features are proof the outcome is possible
Jargon overload
Industry terms create distance and confusion outside expert audiences
Use the simplest word that carries the meaning; test with someone outside the industry
Weak CTAs ("Submit", "Click here")
Generic CTAs provide no motivation to act
Use first-person, benefit-specific verbs ("Get My Free Report")
Multiple CTAs per page
Splits attention and decision energy; often reduces total conversions
Pick the single most valuable action and optimize the entire page for it
Burying the benefit
Long intros before the value prop cause readers to bounce before they understand the offer
State the primary benefit in the headline or first sentence
Unsupported superlatives signal low credibility; every competitor says the same
Replace with specific, verifiable claims and social proof
Gotchas
Clever headlines that obscure the value - Puns and wordplay feel creative but often tank CTR because readers don't understand the offer. "Where ideas take flight" tells a reader nothing. Test clever headlines against a plain-language alternative; the plain version wins in most A/B tests.
First-person CTA backfire on cold audiences - "Start My Free Trial" outperforms "Start Your Free Trial" for warm audiences but can feel presumptuous for cold traffic who have not yet formed intent. Match CTA ownership language to how well the visitor already understands and wants the product.
Urgency without credibility reads as spam - Countdown timers and "last chance" copy work when the scarcity is real. Fake urgency (a timer that resets on refresh) trains readers to ignore your CTAs entirely and damages brand trust. Only use urgency when it is genuine.
Social proof that's too vague to be persuasive - "Trusted by 10,000 teams" is weaker than "10,000 engineering teams use this to ship faster." Numbers need context. "Used by Fortune 500 companies" without naming them provides almost no trust signal. Specific, named proof converts; generic claims don't.
Copy optimized for desktop ignores mobile readers - Subject lines over 50 characters get cut on mobile. Above-the-fold copy that requires scrolling on a phone means most visitors never see the CTA. Review all hero copy and CTAs at 375px width before publishing.
