| Mode | When to Use | Input | Output |
|------|-------------|-------|--------|
| A β Build | Starting ads for the first time | Product info + budget + margins | Platform recommendation + budget split + campaign briefs + ad copy |
| B β Optimize | Running ads but want better results | Per-platform ROAS/CPA data | Cross-platform audit + budget reallocation + optimization actions |
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?
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.

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:
| Info | Why It's Needed |
|------|----------------|
| Product price + cost/margin | Calculate break-even ROAS and Max CPA |
| Monthly ad budget | Allocate across platforms |
| Buyer behavior type | Determines which platform is primary (see below) |
| Existing website traffic / email list | Determines if retargeting is viable |
Mode B critical info:
| Info | Why It's Needed |
|------|----------------|
| Per-platform spend + ROAS/CPA | Audit each platform's performance |
| Profit margin | Calculate break-even ROAS |
| Campaign duration | New campaigns need 2-4 weeks before optimization |
Step 3: One follow-up. Ask only for missing critical items. Always include the buyer behavior question for Mode A:
Mode A example:
"Nice β 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') β they know what they want
b) They discover it visually β they see it and want it (lifestyle, fashion, decor)
c) They need to see it in action β demo/video is what sells it
d) Not sure β 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 β 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:
---
The universal metric across all platforms. ROAS = Revenue Γ· Ad Spend. A 4:1 ROAS means $4 revenue for every $1 spent.
The minimum ROAS needed to not lose money: Break-even ROAS = 1 Γ· Profit Margin
| Profit Margin | Break-even ROAS | Meaning |
|:-------------:|:---------------:|---------|
| 25% | 4.0x | Need $4 revenue per $1 ad spend just to break even |
| 33% | 3.0x | |
| 50% | 2.0x | |
| 60% | 1.67x | |
| 75% | 1.33x | Higher margin = more room for ad spend |
Break-even ROAS + profit buffer. Typically 1.5-2x the break-even ROAS for sustainable growth.
| Platform | Average ROAS | Top Quartile | Best For |
|----------|:-----------:|:------------:|----------|
| Google Ads (Shopping) | 4.5x | 6x+ | High-intent buyers (they're already searching) |
| Meta Ads (FB/IG) | 2.2x | 4-5x | Visual products, impulse buys, retargeting (3.6x) |
| TikTok Ads | 1.4x | 2x+ | Product discovery, demo-driven, younger audiences |
Industry-wide ecommerce average: 2.87x
Maximum you can pay to acquire one customer: Max CPA = Average Order Value Γ Profit Margin. Example: $34 product Γ 50% margin = $17 max CPA.
