Practical bid management, keyword harvesting, and campaign structure tactics that lowered client ACoS by an average of 38% last quarter.
Amazon PPC is the biggest lever — and the biggest leak — for most FBA sellers. We've audited hundreds of accounts where 40%+ ACoS was bleeding profit on keywords that would never convert. The fix isn't spending less; it's spending smarter with a structured campaign architecture.
Campaign Structure That Scales
We run a four-tier campaign structure for every ASIN: Branded Defense (exact match on brand terms), Category Conquest (broad + phrase on category keywords), Product Targeting (competitor ASINs), and Auto-Discovery (auto campaigns for keyword harvesting). Each tier has different bid strategies and budget allocations.
Budget allocation framework:
- Branded Defense: 10% of budget — protect your brand at low CPCs
- Category Conquest: 50% of budget — primary growth driver
- Product Targeting: 25% of budget — steal competitor traffic
- Auto-Discovery: 15% of budget — feed keywords into manual campaigns
The Weekly Optimization Ritual
Every Monday, we pull search term reports for the past 14 days. Keywords with 2+ orders and ACoS below target get promoted to exact-match campaigns with increased bids. Keywords with $15+ spend and zero orders get negated immediately. This single habit cuts wasted spend by 20–30% within a month.
Bid adjustments follow a simple rule: if a keyword's ACoS is below your target, increase bid by 10%. If it's 1.5x your target ACoS, decrease by 15%. If it's 2x+ your target with 10+ clicks, pause and investigate — the listing or offer may be the problem, not the bid.
Dayparting and Placement Modifiers
Not all hours and placements convert equally. We analyze placement reports weekly and apply modifiers: Top of Search gets +30–50% for proven converters, Product Pages get -20–40% unless data shows strong performance. For brands with enough data, dayparting rules reduce bids by 30% during low-conversion hours (typically 1–6 AM in the target market).
“The goal of Amazon PPC isn't the lowest ACoS — it's the highest profit. A 25% ACoS keyword that drives $10K/month in sales beats a 10% ACoS keyword doing $500.”
When to Scale vs. When to Cut
Scale when: overall account ACoS is at or below target, organic rank is improving for your top keywords, and inventory can support 30+ days of stock at increased velocity. Cut when: TACoS (total ACoS including organic) is rising despite PPC optimizations, or conversion rate drops below 8% — that's a listing problem, not a PPC problem.
