What is
ROAS
?
Return on Ad Spend (ROAS) is a marketing metric that measures the amount of revenue a business earns for every dollar it spends on advertising. It is the primary way that digital marketing teams evaluate the efficiency of specific campaigns on platforms like Google Ads, Meta, and LinkedIn. ROAS is calculated by dividing the gross revenue attributed to an ad campaign by the total cost of that campaign. A 4:1 ROAS means that for every $1 spent, the company earned $4 in revenue. While a high ROAS is generally positive, it must be balanced against the product's gross margins to ensure true profitability. For example, a 2:1 ROAS might be profitable for a high-margin software product but would be a losing strategy for a low-margin retail store. ROAS is a 'short-term' efficiency metric that tells you which ads are working today, but it should always be viewed alongside LTV to understand the long-term impact of those acquired customers on the business.
Frequently asked questions.
What is a break-even ROAS?
The point where your ad revenue covers both the ad spend and the cost of goods sold (COGS).
How is ROAS different from ROI?
ROAS only looks at revenue vs ad spend; ROI accounts for all business expenses including salaries.
Why is my ROAS dropping while spend stays the same?
This often indicates ad fatigue, reaching audience saturation, or a decline in landing page conversion.
Should I track ROAS at the campaign level?
Yes, individual campaign tracking allows you to move budget from losers to winners instantly.
Is 4x a good ROAS?
For e-commerce, 4x is a standard healthy benchmark, but it depends entirely on your product margins.
