## Understanding ROAS

\*\*Return on Ad Spend (ROAS)\*\* measures how much revenue you make for every dollar spent on advertising. The formula is simple:

ROAS = Total Revenue / Total Ad Spend

\*\*Example:\*\* If you spend $1,000 on ads and generate $5,000 in revenue, your ROAS is 5:1 (or 5x).

\*\*Healthy Benchmarks:\*\* Most Amazon sellers aim for ROAS of 2.5x to 5x, depending on:

- Product margins

- Market competition

- Business goals

A 3:1 ROAS means you're making $3 for every $1 spent, leaving room for costs and profit.## Advertising Cost of Sales (ACoS)

\*\*ACoS\*\* is the inverse of ROAS and shows what percentage of sales revenue goes toward advertising.

ACoS % = (Total Ad Spend / Total Sales) × 100

\*\*Example:\*\* $1,000 in ad spend with $5,000 in revenue = 20% ACoS

\*\*Target ACoS:\*\* Ranges from 15-40% depending on margins. Lower is better, but must be sustainable for growth.

## Click-Through Rate (CTR)

\*\*CTR\*\* measures how many people click your ad versus impressions.

CTR % = (Clicks / Impressions) × 100

Typical Amazon PPC CTR ranges from 0.2% to 2.0%. A declining CTR may indicate:

- Stale ad creative

- Poor keyword relevance

- Increased competition

## Conversion Rate\*\*Conversion Rate\*\* shows what percentage of clicks result in purchases.

Conversion Rate % = (Purchases / Clicks) × 100

Average Amazon conversion rates are 10-15% for PPC. If yours is lower:

- Review product quality/pricing

- Improve product listing

- Check for technical issues

## Cost Per Click (CPC)\*\*CPC\*\* is what Amazon charges per ad click.

CPC = Total Ad Spend / Total Clicks

Factors affecting CPC:

- Keyword competition

- Product category

- Bid amount

- Quality Score
