What copywriting does

The skill kicks in when you ask for a headline, ad text, CTA or email. It sorts the task along three lines: context (ad, landing page, email, button), goal (awareness, consideration, conversion, retention) and audience with its pain points. Then it picks a framework and drafts the copy.

Inside there is a table of frameworks: PAS (problem, agitation, solution), AIDA, BAB, FAB and the 4 U's. Headline formulas get their own section, as do CTA rules and the gap between ad copy and page copy. The promise in an ad has to match the page headline, otherwise bounce goes up. Output is a framework recommendation, 2–3 headline variants, body structure, CTA options and A/B test ideas.

If the project has a contextus.md, the skill reads it and loads only the modules this task needs. Without it, it works from project material or your own facts and asks for what is missing. Long-form bodies — blog posts, guides — belong to article-content instead.

What it helps with

  • draft a landing page headline and check its length for search results
  • write ad copy that fits a platform's character limit
  • rewrite a CTA so it leads with an action verb instead of "Submit"
  • lay out an email with AIDA and get subject line variants
  • find an angle competitors are not already using

Example prompts for the agent

  • Write 3 headline variants for the landing page using PAS
  • Rewrite the CTA on the pricing page, right now it says "Submit"
  • Draft a cold outreach email with the AIDA framework

# Content: Copywriting

Guides **short-form marketing copy**—ads, landing pages, email, CTAs. Copywriting frameworks (PAS, AIDA, BAB) provide structure for conversion-focused copy. For **article body content** (blog posts, guides, long-form), see **article-content**.

**When invoking**: On **first use**, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On **subsequent use** or when the user asks to skip, go directly to the main output.

## Initial Assessment

**Project context:** Read root `contextus.md` when present and load only the modules relevant to this task. Without Contextus, use available project material or user-provided facts and ask for missing information; do not create a parallel context system.

Identify:
1. **Context**: Ad, landing page, email, CTA, or general
2. **Goal**: Awareness, consideration, conversion, retention
3. **Audience**: ICP, stage, pain points

## Copywriting Frameworks

| Framework | Structure | Best For |
|-----------|-----------|----------|
| **PAS** | Problem → Agitation → Solution | Direct-response; sales pages; landing pages |
| **AIDA** | Attention → Interest → Desire → Action | Story-driven; ads; emails; editorials |
| **BAB** | Before (problem) → After (outcome) → Bridge (how) | Transformation; testimonials; case studies |
| **FAB** | Features → Advantages → Benefits | Product pages; feature lists |
| **4 U's** | Useful, Urgent, Unique, Ultra-specific | Headlines; subject lines |

### PAS (Problem, Agitation, Solution)

- **Problem**: Identify the reader's pain point clearly
- **Agitation**: Intensify the emotional impact; make the problem feel urgent
- **Solution**: Present your product/service as the answer

### AIDA (Attention, Interest, Desire, Action)

- **Attention**: Grab with a powerful headline or opening
- **Interest**: Build engagement through facts, storytelling, or emotional appeals
- **Desire**: Highlight benefits and how the product solves problems
- **Action**: Include a clear call-to-action

### BAB (Before, After, Bridge)

- **Before**: Current problem state
- **After**: Desired outcome
- **Bridge**: How your solution bridges the gap

## Headline Formulas

| Formula | Example |
|---------|---------|
| **How to [outcome]** | "How to Double Your Conversions in 30 Days" |
| **[Number] Ways to [benefit]** | "7 Ways to Reduce Churn Without Hiring" |
| **[Who] + [benefit]** | "For Marketers Who Want to Ship Faster" |
| **[Problem]? Here's [solution]** | "Struggling with SEO? Here's the Fix" |
| **[Before] → [After]** | "From 0 to 10K Users in 90 Days" |
| **The [adjective] [noun] for [audience]** | "The Ultimate Guide for SaaS Founders" |

**Rules**: Front-load keywords; keep under 60 chars for SERP; avoid clickbait; match ad-to-page alignment.

**Information gain (differentiation)**: Copy that restates what competitors say adds zero value. Lead with unique angle, proprietary data, or contrarian insight. "What does this headline/promise add that others don't?" See **article-content** for full information gain strategy in long-form.

## Copy by Context

| Context | Focus | Skills |
|---------|-------|--------|
| **Ad copy** | Hook, benefit, CTA; platform limits | paid-ads-strategy, google-ads, meta-ads |
| **Landing page** | Headline, value prop, CTA; above fold | landing-page-generator, hero-generator |
| **Email** | Subject line, preview, body, CTA | email-marketing |
| **CTA** | Value-focused; action verb; avoid "Submit" | cta-generator |
| **Article / blog** | Headline formulas, CTA copy; body → **article-content** | article-content, article-page-generator |

## Ad copy vs Landing page copy

| Element | Ad | Landing Page |
|---------|-----|--------------|
| **Promise** | Must match page headline | Same promise; expand on it |
| **Length** | Concise; platform limits | Enough to explain value |
| **CTA** | Click-through; "Learn More" | Conversion; "Start Free Trial" |

**Avoid**: Ad promise not visible on page; mismatch increases bounce.

## CTA Copy Best Practices

- **Value-focused**: "Start Free Trial" not "Submit"
- **Action verb**: "Get," "Try," "Download," "Join"
- **Specific**: "Get Your Free Audit" not "Click Here"
- **A/B test**: Color, copy, placement, size

## Output Format

- **Framework** (PAS, AIDA, BAB) recommendation
- **Headline** options (2–3 variants)
- **Body** copy structure
- **CTA** copy options
- **A/B test** suggestions (if applicable)

## Related Skills

- **article-content**: Article body creation; applies PAS, AIDA, BAB to long-form; headline formulas for article titles
- **landing-page-generator**: Landing page copy and structure
- **hero-generator**: Hero headline, subheadline, CTA
- **cta-generator**: CTA design and copy
- **paid-ads-strategy**: Ad copy frameworks (PAS, BAB, Social Proof)
- **email-marketing**: Email subject lines, body copy
- **branding**: Brand voice, tone consistency
