Marketing Copy Engine 1

Marketing Copy Engine

Your landing page converts 0.8%. Your emails get 12% open rates. Your product descriptions are generic. This skill turns any product/topic into high-converting copy using 12 proven frameworks, 8 tones, and brand-voice consistency.

What it does

• 12 copywriting frameworks — AIDA, PAS, BAB, FAB, 4Ps, QUEST, ACCA, PPP, OIC, CCP, SSS, FORREST
• 8 brand tones — professional, casual, witty, urgent, empathetic, authoritative, playful, luxurious
• 50+ templates — landing pages, hero sections, CTAs, emails, ads, product descriptions, social
• Quality gate — scores copy 0-100 (clarity, persuasion, specificity, emotion, CTA)
• A/B test suggestions — generates 3 variants per piece
• Brand voice lock — consistent tone across all output

When to use it

• You need landing page copy and don't know where to start
• Your current copy converts below 2% and you want a refresh
• You need 5 email variants for a launch sequence
• You're launching a product and need all the copy at once
• Your content sounds AI-generated and you want it to sound human
• You need product descriptions for 100 SKUs

Why it's better than ad-hoc prompting

Most "write me copy" prompts give generic output. This skill is different:

• Framework-driven — not "write something good" but AIDA / PAS / BAB
• Quality scored — every output gets 0-100 with specific improvements
• Variant generation — A/B test ready, not just one version
• Brand-locked — consistent voice across all channels
• Channel-aware — landing page ≠ email ≠ ad; different rules

The 12 frameworks (cheat sheet)

The 8 tones (with examples)

The quality gate (0-100 score)

Every output is scored on:

• Clarity (25 pts) — Jargon-free, Flesch reading ease 60+
• Specificity (20 pts) — Numbers, not "many" or "fast"
• Persuasion (20 pts) — Uses framework structure correctly
• Emotion (20 pts) — At least one emotional trigger
• CTA strength (15 pts) — Clear, specific, low-friction

Sample output (PAS, urgent tone)
