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:

Metric	Goal
ACoS	Lower %
ROAS	Higher ratio

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