Campaign Structure: The Foundation of PPC Performance

Before you can optimize bids or harvest keywords, you need a campaign structure that gives you enough control and enough data. The single biggest mistake Amazon advertisers make is running too few campaigns with too many products bundled together.

The structure that consistently works best is a three-layer approach:

• Brand defense campaigns — exact match on your brand terms, tightly controlled bids
• Core category campaigns — phrase and exact match on your highest-volume keywords, one product per ad group wherever possible
• Discovery campaigns — broad match and auto campaigns for research, with aggressive negative keyword harvesting to prevent bleed

Keyword Optimization: The 80/20 Rule

In any well-run Amazon PPC account, roughly 80% of revenue comes from 20% of keywords. The goal of keyword optimization is to identify that top 20% as quickly as possible and protect it — while ruthlessly cutting the long tail that’s draining budget without returns.

Start with a keyword performance audit. Sort every keyword in your account by spend descending. For keywords with more than 10 clicks and no conversions, they’re candidates for pausing or bidding down aggressively. For keywords with strong conversion rates and low impression share, you’re leaving revenue on the table — raise bids.

Bid Management: The Art of Marginal ROAS

Effective bid management isn’t about hitting a target ACOS — it’s about understanding the marginal return of each additional dollar spent on each keyword. The most effective bid management cadence for most accounts is: daily monitoring of outlier performance, weekly bid adjustments on your top 50 keywords by spend, and monthly structural reviews.

Negative Keywords: The Hidden Profit Lever

Negative keywords are where most Amazon advertisers leave the most money on the table. Every week that passes without reviewing your search term report for irrelevant queries is a week of wasted spend. For most accounts, a rigorous negative keyword program alone can reduce wasted spend by 15–30%.
