📢 Marketing Copy Prompt

A marketing copy prompt directs an LLM to generate persuasive, brand-consistent content — ad copy, landing pages, email campaigns, product descriptions, and A/B test variants — all aligned to a specific audience, voice, and conversion goal.

Why This Matters

The average person encounters 6,000–10,000 ads per day. To cut through the noise, marketing copy must be specific, emotionally compelling, and laser-focused on the audience's pain points. A well-engineered prompt consistently produces copy that converts — because it encodes the brand voice, audience psychology, and conversion principles that make great marketing work.

**Core Frameworks You Apply:**
- **AIDA:** Attention → Interest → Desire → Action
- **PAS:** Problem → Agitation → Solution
- **BAB:** Before → After → Bridge
- Choose the framework that best fits the content type and goal.

**Brand Context:**
- Brand name: {{brand_name}}
- Brand voice: {{voice}} (e.g., "confident and witty, like a smart friend who works in tech")
- Target audience: {{audience}}
- Key value proposition: {{value_prop}}
- Competitors to differentiate from: {{competitors}}
- Tone words: {{tone_words}} (e.g., bold, approachable, no-nonsense, empathetic)
- Words to avoid: {{avoid_words}} (e.g., "synergy", "revolutionary", "game-changer")

**Task:** {{task_type}}

**Instructions by Content Type:**

**For Ad Copy (Google/Meta/LinkedIn):**
- Write 5 headline variants (under 30 characters each)
- Write 3 description variants (under 90 characters each)
- Include the primary CTA keyword in at least 3 headlines
- Use power words: free, proven, instant, exclusive, limited
- Each variant should test a different angle: pain point, benefit, social proof, urgency

**For Landing Page Copy:**
- Hero section: headline (under 10 words), subheadline (under 25 words), CTA button text
- Problem section: 3 pain points the audience faces
- Solution section: how the product solves each pain point
- Social proof section: suggest testimonial themes and trust signals
- CTA section: urgency-driven closing with clear next step

**For Email Campaigns:**
- Subject line: 5 variants (under 50 characters, optimize for open rate)
- Preview text: matching preview for each subject line
- Email body: hook → value → CTA structure, under 200 words
- P.S. line with an additional incentive or urgency element

**Quality Standards:**
- Every sentence must serve a purpose — no filler
- Lead with benefits, not features
- Use specific numbers over vague claims ("saves 4 hours/week" not "saves time")
- Write at a 6th-grade reading level (Flesch-Kincaid)
- Include at least one element of social proof or specificity per piece

Bad vs. Improved Prompts

❌ Bad Prompt

Write marketing copy for my project management app.

Why it fails: No audience, no brand voice, no content type, no value proposition, no conversion goal. The output will be generic "streamline your workflow" copy that every competitor also uses.

✅ Improved Prompt

You are an expert copywriter specializing in B2B SaaS.

Write Google Ads copy for "TaskForge" — a project management tool built specifically for remote engineering teams of 10-50 people.

Target audience: Engineering managers frustrated with Jira's complexity.
Value prop: Set up in 5 minutes, not 5 days. Built for how engineers actually work.
Brand voice: Confident, slightly irreverent, developer-friendly. Think Stripe's marketing tone.
Words to avoid: "revolutionary", "game-changer", "synergy"

Deliverables:
1. 5 headline variants (under 30 chars each) — test these angles: pain point, speed, simplicity, social proof, contrast with Jira
2. 3 description variants (under 90 chars each) — lead with a benefit + specific number
3. For each variant, note which psychological trigger it uses (urgency, social proof, curiosity, fear of missing out, pain avoidance)

Output as a numbered list grouped by headlines and descriptions.

Tips for Customization

Customization	How to Modify the Prompt
A/B testing	Add: "For each piece of copy, create Variant A (benefit-focused) and Variant B (pain-focused) for split testing"
Seasonal campaign	Add: "This is for a Black Friday campaign running Nov 25–28. Incorporate urgency and limited-time messaging"
Product launch	Switch task: "Write a product launch email sequence: 3 emails over 5 days — teaser, launch day, last chance"
Brand voice sample	Add: "Here is a sample of our brand voice: [paste 2-3 sentences]. Match this tone exactly."
Localization	Add: "Write copy for the German market. Use formal 'Sie' address. Adapt cultural references — don't just translate."
Compliance	Add: "This is for financial services — avoid guaranteed returns language. Include required disclaimer: {{disclaimer}}"

Practice Challenge

Challenge

Pick a product you use daily. Write a marketing copy prompt that:

1. Defines the target audience with specifics (demographics, psychographics, pain points)
2. Specifies the brand voice with a comparison ("like X but more Y")
3. Requests 5 headline variants testing different psychological triggers
4. Sets character limits for each piece

Run it and evaluate: Which headline would you actually click? Which one sounds most like the real brand? Refine and re-run.

Real-World Scenario

Scenario: An ecommerce brand needs to generate product descriptions for 500 SKUs across 4 languages for their holiday catalog.

Implementation approach:

1. Product data feed: export SKU data — product name, category, features, price, materials, dimensions
2. Template prompt: one master copy prompt per category (electronics, apparel, home goods) with brand voice locked in
3. Per-SKU generation: inject each product's data into the template and generate: 50-word description, 3 bullet points, meta description
4. A/B variants: generate 2 variants per SKU — one benefit-led, one feature-led — for multivariate testing
5. Multi-language: run a second pass with localization prompts (not translation — cultural adaptation)
6. Quality gates: automated checks for character limits, banned words, reading level score
7. Human review: copywriters review 10% random sample to calibrate quality

Temperature: 0.8 for creative variety across variants, 0.4 for brand-consistent descriptions.

This produces 500 product descriptions in under 2 hours vs. 2 weeks of manual copywriting.

Interview Question

Interview Question

Q: How would you maintain brand voice consistency across hundreds of AI-generated marketing assets?

A: Brand voice consistency requires constraints at multiple levels:

1. Voice definition — define the brand voice with specific, testable attributes: "We are witty but never sarcastic. We use contractions. We never use exclamation marks. We reference technology analogies." Include 3–5 examples of on-brand and off-brand sentences
2. Tone words as guardrails — provide explicit lists: "Always: confident, clear, specific. Never: hyperbolic, vague, corporate."
3. Reference samples — include 2–3 paragraphs of approved copy in the system prompt and instruct: "Match this voice exactly"
4. Banned word list — explicitly list words and phrases the brand never uses
5. Automated scoring — build a post-generation classifier that scores new copy against the brand voice rubric, flagging anything below threshold for human review
6. Few-shot anchoring — include examples of the exact output format with the brand voice already applied

Summary

Summary

• Marketing copy prompts must define audience, brand voice, value proposition, and conversion goal
• Always specify the content type (ad, landing page, email) and its format constraints (character limits, structure)
• Use established copywriting frameworks (AIDA, PAS, BAB) to structure persuasive content
• Request multiple variants with different angles for A/B testing
• Use higher temperature (0.7–0.9) for creative variety, lower (0.3–0.5) for brand-consistent output
