Two Modes

Capabilities

• ROAS financial framework: Calculate break-even ROAS, target ROAS, and max CPA from product margins — the foundation for all platform decisions
• Platform recommendation: Match your product type to the right ad channels (search-intent → Google, visual/impulse → Meta, demo/novelty → TikTok)
• Cross-platform budget allocation: Split budget across channels based on expected ROAS and funnel stage
• Google Ads brief: Shopping, Search, and Performance Max campaign structures with keyword direction
• Meta Ads brief: Audience targeting, ad set structure, and creative hooks for Facebook + Instagram
• TikTok Ads brief: Video hook concepts, Spark Ads strategy, and audience targeting
• Ad copy generation: Headlines, descriptions, and CTAs for each platform
• Creative brief: Image/video specs, style direction, hook angles (not actual image/video creation)
• Cross-platform audit: Compare ROAS/CPA across channels and identify where to shift budget

Usage Examples

Mode A — Build New Strategy

I sell handmade candles on Shopify. Price $34, cost $8. Monthly ad budget $2,000. Help me plan which platforms to advertise on.

I'm launching a fitness resistance band set, $29.99, 60% margin. $5,000/month budget. Where should I advertise and how much on each platform?

I have a Shopify store selling pet accessories. Best sellers are dog bandanas ($15) and cat toys ($12). $1,000/month to start. What's my ad strategy?

Mode B — Optimize Existing

Running Google Shopping (ROAS 3.2x, $3,000/mo) and Facebook ($1,800/mo, ROAS 1.4x). Margin is 45%. Should I shift budget?

My TikTok ads get tons of views but barely convert. Google Shopping is profitable. Total budget $4,000/month. Help me optimize.

How This Skill Collects Information

Step 1: Extract from the prompt. Parse product type, price, margins, budget, platforms mentioned, ROAS data, store type.

Step 2: Identify gaps. Compare against what's needed:

Mode A critical info:

Mode B critical info:

Step 3: One follow-up. Ask only for missing critical items. Always include the buyer behavior question for Mode A:

Mode A example:
"Nice — handmade candles at $34 with $2,000/month budget. To plan your 
strategy, I need a few things:

  1. Your product cost per unit (to calculate break-even ROAS)
  2. How do customers typically find products like yours?
     a) They search for it (e.g., 'soy candles') — they know what they want
     b) They discover it visually — they see it and want it (lifestyle, fashion, decor)
     c) They need to see it in action — demo/video is what sells it
     d) Not sure — I'll analyze and recommend
  3. Do you have existing website traffic or an email list?
     (This affects whether retargeting is viable from day one)"

Mode B example:
"Got it — Google and Facebook running. To audit properly:
  1. Your product margin (or cost + price, I'll calculate)
  2. How long have these campaigns been running? (New campaigns 
     need 2-4 weeks before optimization)"

The buyer behavior answer directly determines platform selection:

• a) Search → Google Shopping / Search is primary
• b) Visual → Meta Ads (Facebook / Instagram) is primary
• c) Demo → TikTok Ads is primary
• d) Not sure → Infer from product type, mark as ⚠️ estimated

Step 4: Use estimates when stuck. Don't block on missing data — use category benchmarks, but:

• Mark every estimate clearly in the output with ⚠️ (e.g., "⚠️ Estimated: conversion rate 2.5% based on home decor category average")
• Explain what better data would change (e.g., "If you can share your actual Shopify conversion rate, I can recalculate the ROAS target and budget split more accurately")
• List what to provide next time at the end of the report for more precise results

Key Concepts

ROAS (Return on Ad Spend)

The universal metric across all platforms. ROAS = Revenue ÷ Ad Spend. A 4:1 ROAS means $4 revenue for every $1 spent.

Break-even ROAS

The minimum ROAS needed to not lose money: Break-even ROAS = 1 ÷ Profit Margin

Target ROAS

Break-even ROAS + profit buffer. Typically 1.5-2x the break-even ROAS for sustainable growth.

Platform ROAS Benchmarks (2025-2026)

Industry-wide ecommerce average: 2.87x

Max CPA (Cost per Acquisition)

Maximum you can pay to acquire one customer: Max CPA = Average Order Value × Profit Margin. Example: $34 product × 50% margin = $17 max CPA.

Mode A Workflow — Build Strategy

Step A1: Collect Product Info

Step A2: Calculate ROAS Framework

📊 CROSS-PLATFORM FINANCIAL FRAMEWORK

Product Price (AOV):     $34.00
Product Cost:            $8.00
Profit Margin:           76.5%

Break-even ROAS:         1.31x ($1 ad spend must generate $1.31 revenue)
Target ROAS:             2.5x (maintains ~36% profit after ads)
Max CPA:                 $26.01 (max cost to acquire one sale)

Monthly Ad Budget:       $2,000
At Target ROAS (2.5x):   $5,000 expected monthly ad revenue
At Break-even (1.31x):   $2,620 minimum monthly ad revenue

Step A3: Recommend Platform Mix

Match the product to the right platforms based on product characteristics:
