Amazon advertising is a pay-to-play channel where campaign structure determines whether you scale profitably or bleed budget on irrelevant clicks. Amazon PPC helps you design Sponsored Products, Sponsored Brands, and Sponsored Display campaign architectures from scratch — or restructure messy existing accounts — with clear keyword match type strategies, bid logic, negative keyword funnels, and budget allocation rules tied to your actual margin and ACoS targets.

This skill addresses these specific problems:
Before building any campaign, calculate the maximum allowable ACoS:
text
Max ACoS = Gross Margin %
Target ACoS = Gross Margin % - 5 to 10%
Max CPC = (Average Selling Price × Target ACoS) × Estimated Conversion Rate
Example: $30 product, 40% margin, 10% CVR → Max CPC = $30 × 0.35 × 0.10 = $1.05
This number governs every bid decision. Never let campaigns run without a ceiling derived from real unit economics.
Create four campaign tiers with explicit purposes:
Tier 1 — Research (Auto + Broad): Discovers new search terms. High impression volume, lower bids. Daily review of search term reports to identify converting queries.
Tier 2 — Performance (Phrase + Exact): Captures confirmed winners from Tier 1. Higher bids justified by known conversion data. Tightly controlled with exact negatives.
Tier 3 — Brand Defense: Protects branded terms from competitor conquest. Exact match only. Usually small budget but non-negotiable for established products.
Tier 4 — Competitor Targeting: ASIN targeting and keyword conquest of competitor product pages. Experimental budget, tracked separately.
For each seed keyword:
For auto campaigns: Set a low flat bid (30-50% of exact bid) and use category/product targeting for complementary ASIN discovery.
Day 1 negatives (add before launching):
Ongoing waterfall rules:
During launch (first 30 days), weight budget toward research:
Increase Tier 2 weight as confirmed exact-match winners accumulate. By day 60, most budget should shift to performance campaigns.
Platform placement data shows top-of-search typically converts 2-3× better than rest-of-search for most categories. Adjust accordingly:

Day-1 negatives added: "silicone spatula craft", "spatula school", "free spatula"
30-day outcome: Auto campaign discovered "flexible spatula for eggs" and "BPA-free cooking spatula" as converting terms → both moved to dedicated exact match campaigns by Day 21.

Expected result: ACoS reduction from 61% to target range within 14-21 days as budget shifts to proven exact terms.
Launching with only auto campaigns — Auto gives Amazon maximum control and often routes budget to irrelevant terms. Always pair with at least one manual exact campaign.
Setting ACoS targets without checking margin — A 30% ACoS target on a product with 25% margin is a guaranteed loss. Always derive target ACoS from unit economics first.
Never adding negative keywords — Even excellent products will have irrelevant search volume. Not adding negatives is an ongoing tax on every campaign dollar.
Bidding the same amount in auto and exact campaigns — Auto campaigns should bid lower because they're discovery vehicles. Matching bids means overpaying for unknown traffic.
Graduating search terms too early — Moving a term to exact match after 1-2 orders can mislead. Statistical confidence requires 5+ conversions before bid optimization is meaningful.
Ignoring placement multipliers — Top-of-search typically converts better, but the default setting applies no premium. Failing to test placement adjustments leaves performance on the table.
Running all campaigns on the same daily budget — Discovery campaigns need room to find new terms. Underfunding auto campaigns starves the system of new search term data.
Never pausing underperformers — Campaigns with 60+ days of data and no conversions at 3× target ACoS are not going to improve. Pause, investigate, restructure.
Confusing branded and non-branded ACoS — Branded terms convert higher and need lower bids. Mixing them into non-branded campaigns inflates overall ACoS and obscures true performance.
No campaign naming convention — Without consistent naming, you can't filter or sort campaigns at scale. Always include: campaign type, match type, keyword theme, and product identifier.
