The Ultimate Beginner’s Guide to Amazon Advertising Metrics: CPC, ACOS, ROAS Explained

If you’re running Amazon ads, understanding the right Amazon advertising metrics is the difference between scaling your sales or burning your budget. In this complete beginner’s guide, you’ll learn what CPC, ACOS, and ROAS mean, why they matter, and how to improve them to grow your Amazon business.


What Are Amazon Advertising Metrics? (And Why They Matter)

Metrics tell you if your Amazon ads are working or wasting money. Tracking Amazon advertising metrics ensures:

  • You cut wasted ad spend
  • You boost ad profitability
  • You scale without guessing

Many Amazon sellers face these challenges:

  • High ACoS (Advertising Cost of Sales) that kills profits
  • Low ROAS (Return on Ad Spend) making ads unsustainable
  • Rising CPC (Cost Per Click) with no sales

Without data, your Amazon PPC is just luck.

Key Amazon Advertising Metrics Explained

1. CPC (Cost Per Click)

Definition: The average cost you pay when someone clicks on your ad.

Why It Matters:

  • High CPC eats your ad budget fast.
  • Low CPC + no sales = bad targeting.

Example: Your keyword “wireless headphones” costs $2.50 per click but has low conversions. Here’s what to do:

  • Switch to long-tail keywords like “best wireless headphones for running.”
  • Use negative keywords to block irrelevant traffic.

Or let Bidventor adjust bids to prevent overspending.


2. ACoS (Advertising Cost of Sales)

Definition: The percentage of ad spend compared to sales revenue.

Formula: (Ad Spend ÷ Sales) x 100%

Why It Matters:

  • Lower ACoS = more profit.
  • High ACoS = wasted spend.

Example: Spend $10, make $50 in sales = ACoS of 20%.

Strategy:

  • Set a target ACoS based on product margins.
  • Use Bidventor to automatically adjust bids to hit your goal.

3. ROAS (Return on Ad Spend)

Definition: The total revenue earned for each dollar spent on ads.

Formula: Sales Revenue ÷ Ad Spend

Why It Matters:

  • Higher ROAS = better ad efficiency.

Example: Spend $100 on ads, generate $500 in sales = 5x ROAS.

Strategy:

  • Shift more budget to high-ROAS campaigns.
  • Let Bidventor auto-optimize for winning keywords.

ACoS vs. ROAS: Key Difference

Both ACoS and ROAS show how efficient your ads are, but they look at it differently:

MetricGoal
ACoSLower %
ROASHigher ratio

  • If ACoS = 25%, ROAS = 4x.
  • Lower ACoS means higher ROAS.

How to Use Amazon Advertising Metrics to Improve Campaigns

Lower Your CPC:

  • Identify expensive keywords.
  • Test broader or more specific search terms.

Set ACoS Targets:

  • Know your break-even ACoS.
  • Use automation to maintain profitability.
