Campaign structure isn't exciting. It doesn't feel like strategy. But in my experience managing $8M+ in Amazon ad spend across 30+ brands, poor campaign structure is the single most common reason accounts plateau — the spend keeps going up, but the efficiency never improves.
When everything is in one campaign, you can't isolate what's working. You can't protect your best keywords. You can't set different ACoS targets for different objectives. And you definitely can't scale without spending yourself into unprofitability.
Here's the architecture I use — and why each component exists.
The 5-Campaign Core Architecture
For a mature product, I run five distinct campaign types. Each has a specific job, its own budget, and its own success metric.
Auto Campaign — Discovery
Low bids ($0.30–0.50), capped budget. The job of this campaign is purely to discover new search terms — not to drive revenue efficiently. Every week, pull the search term report and harvest converting terms into exact match campaigns. Aggressively add non-converting terms as negatives.
Exact Match — Core Keywords
Your 5–15 proven converting keywords, each in their own exact match campaign with a dedicated daily budget. These are keywords that have demonstrated profitable conversion in your account. They get priority budget and bids set just below break-even ACoS. These campaigns should never run out of budget.
Broad / Phrase Match — Expansion
Secondary keywords in broad or phrase match, used to expand coverage and surface new variations. These feed the exact match campaigns — any term that converts 3+ times here gets promoted to an exact match campaign. Moderate bids, moderate budget.
Brand Defense — Own ASINs
Target your own ASINs with Sponsored Products at a low bid. This fills the "related products" carousel on your listing with your own products instead of competitors. The cost is minimal (you're rarely outbid on your own ASINs) and it prevents margin leakage to competitors at the most critical conversion moment.
Competitor Targeting — Market Share
ASIN targeting on competitor product pages and keyword targeting on competitor brand terms. Higher ACoS is acceptable here — you're investing in market share, not just efficiency. Evaluate on 30-day windows and track share of voice, not just ACoS.
The Harvesting Workflow
Structure only works if you maintain the flow between campaigns. Here's the weekly routine:
- Pull search term reports from auto and broad/phrase campaigns
- Add negatives — any term with 5+ clicks and 0 orders becomes a negative keyword in that campaign
- Promote winners — any term with 3+ orders gets added as an exact match keyword in its own campaign (or the existing exact match campaign if similar enough)
- Check budget caps — if your exact match campaigns are hitting daily budget limits, increase the budget. You never want your best keywords to stop serving mid-day.
- Review bid pacing — keywords with improving CVR can support higher bids. Keywords with declining CVR need bid reductions.
Time commitment: This review takes 30–45 minutes per week per product. It's the most important 30 minutes you'll spend on Amazon PPC. Accounts that skip weekly maintenance drift toward inefficiency within 60 days.
Restructure Cut ACoS by 35% in 60 Days
A home goods brand came to me with a single auto campaign and two broad match campaigns running everything — $6,000/month in spend, 38% ACoS, no visibility into what was working. The account had never been structured.
Over 3 weeks, we rebuilt the account into the 5-campaign architecture, harvested the top 12 converting exact match keywords into protected campaigns, and added 200+ negatives from 6 months of ignored search term data.
Same product. Same total budget. Same keywords — just structured so the profitable ones got protected budget and the money-losing terms were cut. The restructure paid for itself in the first month.
