Ad Copy Variants for A/B Testing
Purpose
This skill generates systematic, labeled ad copy variants designed for structured A/B testing across paid advertising platforms. It produces five distinct appeal-angle variants per product — Emotional, Rational, Scarcity, Social Proof, and Problem-Solution — each formatted for the target platform's constraints and policies. A built-in compliance checker flags potential ad policy violations before launch. Designed for performance marketers and media buyers who need testable, measurable creative variations, not random copy suggestions.
Triggers

Workflow
- Receive product info + target ad platform(s) from user: product name, key benefits, target audience, budget tier, and campaign goal.
- Generate the 5-angle variant matrix:
- Emotional: Tap into desire, aspiration, or joy - Rational: Feature-driven, logical, value-focused - Scarcity: Limited-time, limited-quantity (ethically constrained) - Social Proof: User numbers, ratings, endorsements (only if verifiable) - Problem-Solution: Pain point → product as solution
- Apply platform-specific constraints: character limits (e.g., WeChat Moments: 40 chars headline; Google: 30/90/90), image-text ratio rules, and forbidden content categories.
- Run a compliance check against the target platform's ad policies, flagging: prohibited claims, missing disclosures, superlatives without substantiation, sensitive categories.
- Generate CTA alternatives for each variant — platform-appropriate and conversion-optimized.
- Output the full variant matrix, labeled and ready for ad platform upload.
Prompt Templates
1. Variant Matrix (variant_matrix)
Purpose: Generate the full 5-angle A/B variant matrix. Input:
${product_name}— Product${key_benefits}— 2–3 main benefits${target_audience}— Demographic and psychographic${platform}— Ad platform name${campaign_goal}— Awareness/Consideration/Conversion
Output: A labeled 5-variant table: Variant Label | Headline | Body/Description | CTA | Character Counts.
2. Ad Compliance Check (ad_compliance_check)

${ad_copy_full}— Complete ad text (headline + body + CTA)${platform}— Target ad platform${product_category}— Product category (for restricted category checks)
Output: Compliance report: Flag | Severity | Issue Description | Suggested Fix.
3. CTA Optimizer (cta_optimizer)
Purpose: Generate alternative CTAs for existing ad copy. Input:
${ad_copy}— Existing ad body text${platform}— Platform context${goal}— Click/Conversion/Engagement
Output: 3 CTA alternatives with rationale for each and platform-fit score.
4. Headline Bank (headline_bank)
Purpose: Generate 10 headline angles for a product. Input:
${product_name}— Product${target_audience}— Audience${platform}— Platform (determines character limits)
Output: 10 headlines labeled by angle type (curiosity, benefit, question, statistic, comparison, emotional, how-to, direct, testimonial, news) with character count.
5. Ad Fatigue Refresher (ad_fatigue_refresher)
Purpose: Refresh an existing top-performing ad with new variants. Input:
${current_top_ad}— Currently best-performing ad copy${performance_metric}— What metric (CTR/conversion) it leads on${fatigue_signal}— Why refresh (frequency up, CTR dropping)
Output: 3 refreshed variants that preserve winning elements but change angle, format, or CTA.
Output Format
All variants are delivered in a structured A/B test matrix:
| Variant # | Angle Type | Headline | Body (truncated) | CTA | Expected Audience Response |
|---|---|---|---|---|---|
| A | Emotional | ... | ... | ... | ... |
| B | Rational | ... | ... | ... | ... |
Plus compliance flags table when requested.
Safety Rules
- NEVER include forbidden claims per platform ad policy (health guarantees, financial returns, weight loss promises)
- NEVER use discriminatory, exclusionary, or exploitative language
- NEVER include misleading before/after representations without verifiable data
- NEVER use unsubstantiated superlatives ("best", "#1", "top-rated") unless independently verifiable
- ALWAYS include required disclosures: "Ad", "Sponsored", "Promotion" per platform
- ALWAYS flag sensitive product categories (health, finance, supplements) for extra review
Examples
Example 1: Variant Matrix for WeChat Moments
Input: Product="在线英语课程", Audience="25-35岁职场人", Platform="WeChat Moments", Goal="Conversion" Output: 5 variants: Emotional ("遇见更好的自己"), Rational ("每天15分钟，3个月流利对话"), Scarcity ("限时优惠，仅剩200名额"), Social Proof ("10万+学员的选择"), Problem-Solution ("开会不敢开口？试试这个方法").
Example 2: Compliance Check
Input: Ad copy with "100% guaranteed results in 7 days", Platform="Google Ads", Category="Education" Output: HIGH severity flag: absolute guarantee claim without substantiation. Suggested: "Join 10,000+ learners" instead.
