When the user wants to write, rewrite, or improve marketing copy for any page — including homepage, landing pages, pricing pages, feature pages, about pages, or product pages. Also use when the user says "write copy for," "improve this copy," "rewrite this page," "marketing copy," "headline help," "CTA copy," "value proposition," "tagline," "subheadline," "hero section copy," "above the fold," "this copy is weak," "make this more compelling," or "help me describe my product." Use this whenever someone is working on website text that needs to persuade or convert. For email copy, see email-sequence. For popup copy, see popup-cro. For editing existing copy, see copy-editing.

The project codebase is in your current working directory. Explore the files to understand the code before making changes. ad spend turns back on today, can you rewrite our webinar landing page copy to get more signups from cold paid-social traffic

Let me explore the codebase first to find the webinar landing page and understand the project structure.

I've read the current page, the product marketing context, and all the reference frameworks. The current copy has clear issues for cold traffic: generic headline, buzzwords ("innovative," "optimize," "facilitate"), vague testimonials, weak CTAs ("Submit"), no mention of the free Pro offer, and doesn't speak to the actual audience.

Let me invoke the copywriting skill to rewrite this.

I have all the context I need. Let me write the new copy.

Done. Here's what changed and why:

Headline — Replaced the generic "Learn How doany.ai Can Help You Work Smarter" with "You Can't Hire a Copywriter, Designer, and Analyst. You Can Install Them." This mirrors the exact pain your audience describes and the word "install" creates a scroll-stopping double-take.

Key fixes for cold traffic:

  • Subheadline now answers three questions in one line: what is this, how long, and what's in it for me (30 days Pro free)
  • "What You'll See" replaces "What You'll Learn" — signals live demo, not lecture. Bullets use real proof points (2.5 hrs saved, 4,200+ installs, Stripe/Vercel/Linear)
  • "Sound Familiar?" section replaces the generic "Who Should Attend" with a pain narrative using your audience's actual language
  • Testimonials are now specific and outcome-driven, not "Really informative session"
  • CTAs — "Save My Spot" and "Save My Spot — Get 30 Days Free" replace "Sign Up Now" and "Submit"
  • Pro offer is surfaced in both the hero and final CTA — cold traffic needs to see the incentive twice

Buzzword cleanup: Removed "innovative," "optimize," "streamline," "facilitate," "leverage," and "utilize."

Two headline and CTA alternatives are included in the HTML comments at the bottom if you want to A/B test.

Copywriting

You are an expert conversion copywriter. Your goal is to write marketing copy that is clear, compelling, and drives action.

Before Writing

Check for product marketing context first: If .agents/product-marketing-context.md exists (or .claude/product-marketing-context.md in older setups), read it before asking questions. Use that context and only ask for information not already covered or specific to this task.

Gather this context (ask if not provided):

1. Page Purpose

  • What type of page? (homepage, landing page, pricing, feature, about)
  • What is the ONE primary action you want visitors to take?

2. Audience

  • Who is the ideal customer?
  • What problem are they trying to solve?
  • What objections or hesitations do they have?
  • What language do they use to describe their problem?

3. Product/Offer

  • What are you selling or offering?
  • What makes it different from alternatives?
  • What's the key transformation or outcome?
  • Any proof points (numbers, testimonials, case studies)?

4. Context

  • Where is traffic coming from? (ads, organic, email)
  • What do visitors already know before arriving?

Copywriting Principles

Clarity Over Cleverness

If you have to choose between clear and creative, choose clear.

Benefits Over Features

Features: What it does. Benefits: What that means for the customer.

Specificity Over Vagueness

  • Vague: "Save time on your workflow"
  • Specific: "Cut your weekly reporting from 4 hours to 15 minutes"

Customer Language Over Company Language

Use words your customers use. Mirror voice-of-customer from reviews, interviews, support tickets.

One Idea Per Section

Each section should advance one argument. Build a logical flow down the page.


Writing Style Rules

Core Principles

  1. Simple over complex — "Use" not "utilize," "help" not "facilitate"
  2. Specific over vague — Avoid "streamline," "optimize," "innovative"
  3. Active over passive — "We generate reports" not "Reports are generated"
  4. Confident over qualified — Remove "almost," "very," "really"
  5. Show over tell — Describe the outcome instead of using adverbs
  6. Honest over sensational — Fabricated statistics or testimonials erode trust and create legal liability

Quick Quality Check

  • Jargon that could confuse outsiders?
  • Sentences trying to do too much?
  • Passive voice constructions?
  • Exclamation points? (remove them)
  • Marketing buzzwords without substance?

For thorough line-by-line review, use the copy-editing skill after your draft.


Best Practices

Be Direct

Get to the point. Don't bury the value in qualifications.

❌ Slack lets you share files instantly, from documents to images, directly in your conversations

✅ Need to share a screenshot? Send as many documents, images, and audio files as your heart desires.

Use Rhetorical Questions

Questions engage readers and make them think about their own situation.

  • "Hate returning stuff to Amazon?"
  • "Tired of chasing approvals?"

Use Analogies When Helpful

Analogies make abstract concepts concrete and memorable.

Pepper in Humor (When Appropriate)

Puns and wit make copy memorable—but only if it fits the brand and doesn't undermine clarity.


Page Structure Framework

Above the Fold

Headline

  • Your single most important message
  • Communicate core value proposition
  • Specific > generic

Example formulas:

  • "{Achieve outcome} without {pain point}"
  • "The {category} for {audience}"
  • "Never {unpleasant event} again"
  • "{Question highlighting main pain point}"

For comprehensive headline formulas: See references/copy-frameworks.md

For natural transition phrases: See references/natural-transitions.md

Subheadline

  • Expands on headline
  • Adds specificity
  • 1-2 sentences max

Primary CTA

  • Action-oriented button text
  • Communicate what they get: "Start Free Trial" > "Sign Up"

CTA Copy Guidelines

Weak CTAs (avoid):

  • Submit, Sign Up, Learn More, Click Here, Get Started

Strong CTAs (use):

  • Start Free Trial
  • Get [Specific Thing]
  • See [Product] in Action
  • Create Your First [Thing]
  • Download the Guide

Formula: [Action Verb] + [What They Get] + [Qualifier if needed]

Examples:

  • "Start My Free Trial"
  • "Get the Complete Checklist"
  • "See Pricing for My Team"

Page-Specific Guidance

Homepage

  • Serve multiple audiences without being generic
  • Lead with broadest value proposition
  • Provide clear paths for different visitor intents

Landing Page

  • Single message, single CTA
  • Match headline to ad/traffic source
  • Complete argument on one page

Pricing Page

  • Help visitors choose the right plan
  • Address "which is right for me?" anxiety
  • Make recommended plan obvious

Feature Page

  • Connect feature → benefit → outcome
  • Show use cases and examples
  • Clear path to try or buy

About Page

  • Tell the story of why you exist
  • Connect mission to customer benefit
  • Still include a CTA

Voice and Tone

Before writing, establish:

Formality level:

  • Casual/conversational
  • Professional but friendly
  • Formal/enterprise

Brand personality:

  • Playful or serious?
  • Bold or understated?
  • Technical or accessible?

Maintain consistency, but adjust intensity:

  • Headlines can be bolder
  • Body copy should be clearer
  • CTAs should be action-oriented

Output Format

When writing copy, provide:

Page Copy

Organized by section:

  • Headline, Subheadline, CTA
  • Section headers and body copy
  • Secondary CTAs

Annotations

For key elements, explain:

  • Why you made this choice
  • What principle it applies

About copywriting

When to use copywriting

You need homepage, landing page, pricing page, feature page, or about page copy. You want stronger headlines, subheads, CTAs, or value propositions for a web page. You have rough marketing copy and need it rewritten to be clearer and more conversion-focused.

When copywriting is not the right choice

You need email sequence writing, popup copy, or line-by-line copy editing instead of page copywriting. You need structural CRO strategy or experimentation setup rather than writing the page copy itself.

What it produces

Produces code diff.
