Our methodology replaces revenue-based bidding with profit-aware decision making. Every SKU gets a commercial role. Every pound of spend is traceable to contribution margin.
The 90-Day POAS Implementation
From commercial mapping to full profit-aware bidding in 90 days.
Commercial Mapping
Week 1-2We map every SKU to its true contribution margin by injecting COGS, shipping costs, return rates, and payment processing fees into your product feed. Each product receives a commercial role: Scale (high margin, high volume), Protect (high margin, low volume), Recover (low margin, high volume), or Pause (unprofitable).
This replaces guesswork with data. Most agencies bid on revenue signals. We bid on profit signals. The commercial map becomes the foundation for every decision that follows.
Account Restructure
Week 2-4We rebuild your Google Ads account around margin bands, not product categories. Each band gets its own campaign with a separate tROAS target calibrated to its break-even point. Scale products get aggressive targets. Protect products get conservative targets. Pause products get zero spend.
This structure mirrors your P&L. Your finance team can trace every pound of ad spend to contribution margin, not just attributed revenue.
Feed Architecture
Week 2-3We restructure your product feed to carry commercial intelligence: custom labels for margin bands, return probability scores, stock velocity indicators, and seasonal demand signals. This gives Smart Bidding the context it needs to make profitable decisions.
The feed is your campaign's brain. Without margin data in the feed, the algorithm optimises for what it can see: clicks and conversions. With margin data, it optimises for what matters: profit.
POAS Bidding Implementation
Week 3-5We switch bidding from revenue-based tROAS to margin-aware POAS targets. Conversion values are adjusted to reflect true profit contribution. Smart Bidding learns to favour high-margin products and suppress budget-draining low-margin SKUs.
Expect a 10-20% volume dip in weeks 3-4 as the algorithm recalibrates. Profit improvements typically appear within 6-8 weeks. Full optimisation takes 90 days.
Post-Sale Margin Recovery
OngoingWe build feedback loops that account for returns, partial refunds, and payment settlement delays. Corrected conversion values are fed back into Google Ads so the algorithm learns from actual profit, not projected revenue.
A fashion brand with 30% returns and 60-day BNPL settlement has fundamentally different economics than what Google reports. We close that gap.
Continuous Commercial Optimisation
OngoingWeekly margin-band reviews, monthly P&L reconciliation, and quarterly strategic rebalancing. We adjust SKU roles as seasonality, stock levels, and competitive dynamics shift.
This is not set-and-forget. Markets change. Margins shift. We adapt bidding to commercial reality in real time.
The SKU-Role Framework
Every product is assigned a commercial role based on its margin profile, conversion rate, return rate, and stock depth. Roles determine bidding strategy, budget allocation, and performance targets.
Scale
High margin (>35%), strong conversion rate, adequate stock depth
Aggressive tROAS targets, maximum impression share, broad match expansion
A £45 skincare serum with 62% margin and 2.1% conversion rate
Protect
High margin (>35%), lower volume, niche demand
Conservative targets, exact match focus, maintain profitability
A £180 premium face oil with 58% margin but seasonal demand
Recover
Low margin (<20%), high volume, strategic importance
Tight break-even targets, use as gateway to high-margin upsells
A £12 bestselling moisturiser at 15% margin that drives repeat purchases
Pause
Below break-even margin, high return rate, or out of stock
Zero ad spend, redirect budget to Scale and Protect products
End-of-line sizes with 45% return rates and 8% margin
Margin-Band Bidding
Instead of one blended tROAS target, we create separate campaigns for each margin band with individually calibrated targets.
| Margin Band | Contribution Margin | Break-Even ROAS | Target tROAS | Budget Priority |
|---|---|---|---|---|
| Scale (55%+) | 55-70% | 1.8x | 2.5x | Maximum |
| Protect (35-55%) | 35-55% | 2.9x | 3.5x | Moderate |
| Recover (20-35%) | 20-35% | 5.0x | 5.5x | Minimal |
| Pause (<20%) | <20% | N/A | Excluded | Zero |
Break-even ROAS calculated as 1 ÷ contribution margin %. Targets set above break-even to ensure profitable growth. Reviewed weekly.
Frequently Asked Questions
How long does POAS implementation take?
The full POAS implementation takes 4-6 weeks for account restructuring and feed architecture, followed by a 90-day optimisation period. Profit improvements typically appear within 6-8 weeks. Volume may dip 10-20% during weeks 3-4 as Smart Bidding recalibrates.
What data do I need to provide for POAS bidding?
At minimum: landed COGS per SKU, average shipping cost per order, return rates by product category, and payment processing fees. Ideally, you would also have SKU-level return rates, BNPL settlement timelines, seasonal margin variations, and customer cohort data.
What is the SKU-role framework?
Every product is assigned one of four commercial roles: Scale (high margin, aggressive bidding), Protect (high margin, conservative bidding), Recover (low margin, break-even targeting), or Pause (unprofitable, zero spend). Roles are reviewed weekly and adjusted for seasonality and stock levels.
How do you measure success?
We measure contribution margin (CM3): revenue minus COGS, shipping, returns, payment processing, and ad spend. This is reconciled against your P&L monthly. We also track blended POAS, SKU-level profitability, and working capital efficiency.
Does this work with Performance Max?
Yes. We structure PMax asset groups around margin bands with separate tROAS targets. Brand exclusions prevent cannibalisation. Custom labels in the feed give PMax the commercial context to make profitable decisions rather than chasing volume.
