Purple Cow Audit

Quality gate for affiliate marketers: score a product's remarkability 1-10 before promoting it. Based on Seth Godin's Purple Cow — if the product isn't remarkable, no amount of marketing skill will make it convert sustainably. The key question: "Would I recommend this to a friend WITHOUT earning a commission?"

Stage

S1: Research — Evaluating a program's worthiness IS part of research and discovery. This is a quality gate before you invest time creating content, landing pages, and email sequences.

When to Use

  • User is considering promoting a specific product
  • User asks "is this product worth promoting?"
  • User wants to evaluate product quality before investing time
  • User says "purple cow", "remarkable", "audit", "evaluate", "quality check"
  • Before investing time in S2-S5 skills for a specific product
  • User has a list of programs from affiliate-program-search and needs to pick the best

Input Schema

product:                    # REQUIRED
  name: string              # Product name
  url: string               # Product website
  description: string       # OPTIONAL — what it does
  reward_value: string      # OPTIONAL — commission rate
  tags: string[]            # OPTIONAL — categories

comparison_products: string[] # OPTIONAL — competitors to compare against
                              # Default: auto-discovered

Chaining from S1 affiliate-program-search: If run, evaluate the recommended_program.

Workflow

Step 1: Research the Product

  1. web_search: "[product] review 2024 2025" — find recent reviews
  2. web_search: "[product] vs" OR "[product] alternative" — find competitors
  3. web_search: "[product] complaints" OR "[product] problems" — find issues
  4. Check product website for: pricing transparency, unique features, social proof

Step 2: Score Remarkability

Rate each dimension 1-10:

Dimension Question Weight
Uniqueness Does it do something no competitor does? 20%
Quality Is it genuinely excellent at its core job? 20%
Story Does using it make you feel/look different? 15%
Word of mouth Would users tell friends unprompted? 15%
Design Is the experience delightful, not just functional? 10%
Problem fit Does it solve a real, painful problem? 10%
Trust Transparent pricing, good support, real social proof? 10%

Composite score = weighted average (1-10)

Step 3: Make Recommendation

Based on composite score:

  • 8-10: PROMOTE — This is a Purple Cow. Go all in.
  • 6-7: PROMOTE WITH ANGLE — Good product, needs strong positioning. Identify your unique angle.
  • 4-5: CAUTION — Mediocre product. Only promote if commission is exceptional AND you can add significant value through bonuses.
  • 1-3: SKIP — Not remarkable. Promoting this will damage your reputation. Find an alternative.

Step 4: Identify Remarkable Angles

For products scoring 6+, identify:

  1. The 1-2 features that ARE remarkable (Purple Cow elements)
  2. The angles that make it share-worthy
  3. The audience segment for whom this IS a Purple Cow (even if not for everyone)

Step 5: Self-Validation

  • Score is evidence-based (cited reviews, features, data)
  • Recommendation is honest (not inflated by high commission)
  • Remarkable angles are specific (not generic praise)
  • Comparison with competitors is fair
  • The "would I recommend without commission" test was honestly applied

Error Handling

  • No product provided: "Tell me the product name and I'll audit its remarkability. Or run affiliate-program-search first."
  • Product is too new/no reviews: Score based on available data, flag low confidence. "Limited data — revisit this audit in 3 months."
  • User disagrees with score: "The score is a starting framework. If you have personal experience that changes the picture, tell me and I'll adjust."
  • No alternatives found: Suggest running affiliate-program-search in the same category.

Examples

Example 1: "Is HeyGen worth promoting?" → Research reviews, features, competitors. Score across 7 dimensions. Result: 8/10 PROMOTE — remarkable for AI avatar quality, unique lip-sync tech, strong word of mouth.

Example 2: "Evaluate these 3 programs from my search results" → Score all 3 side-by-side. Compare composite scores. Recommend the Purple Cow.

Example 3: "Should I promote this random SaaS tool?" (generic tool, many competitors) → Research reveals: 5/10 CAUTION — competent but unremarkable. 4 competitors do the same thing. Suggest finding a more remarkable alternative or targeting a micro-audience where it IS remarkable.

Revenue & Action Plan

Expected Outcomes

  • Revenue potential: Choosing an 8+/10 product vs a 5/10 product means 3-5x higher conversion rates. At the same traffic, that's $300-1,500/month vs $100-300/month. Product selection is the highest-leverage decision in affiliate marketing
  • Benchmark: Products scoring 8+ convert at 3-5% CTR, while 4-5 products convert at 0.5-1%. The difference compounds over months
  • Key metric to track: EPC (Earnings Per Click) — after 30 days of promotion, compare your EPC against the program's network average. If yours is below average, the product may not resonate with YOUR audience

Do This Right Now (15 min)

  • If PROMOTE (8-10): Run grand-slam-offer immediately — design your irresistible offer around the remarkable angles identified. Then start creating content today
  • If PROMOTE WITH ANGLE (6-7): Run monopoly-niche-finder to find the specific audience segment where this IS remarkable. Don't promote to a general audience
  • If CAUTION/SKIP (1-5): Run affiliate-program-search to find a better product in the same niche. Don't waste months promoting a mediocre product

Track Your Results

After promoting for 30 days: check EPC. If below $0.50, re-audit the product — the market may not find it as remarkable as the audit suggested. Switch products early; sunk cost is the biggest affiliate mistake.

Next step — copy-paste this prompt: "Design an irresistible offer for [product] using these remarkable angles: [list from audit]" → runs grand-slam-offer
