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

  • "generate ad variants"
  • "A/B test ad copy"
  • "广告文案变体"
  • "ad copy ab test"
  • "create ad copy"
  • "广告A/B测试"
  • "multiple ad versions"
  • "ad variant matrix"
  • "headline bank"
  • "CTA optimizer"

Workflow

  1. Receive product info + target ad platform(s) from user: product name, key benefits, target audience, budget tier, and campaign goal.
  2. 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
  3. 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.
  4. Run a compliance check against the target platform's ad policies, flagging: prohibited claims, missing disclosures, superlatives without substantiation, sensitive categories.
  5. Generate CTA alternatives for each variant — platform-appropriate and conversion-optimized.
  6. 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)

Purpose: Review ad copy for platform-specific policy violations. Input:

  • ${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.
