ROAS (Return on Ad Spend)
Quick answer
What is roas (return on ad spend)?
The amount of revenue generated for every dollar spent on advertising.
In plain English
ROAS is calculated as revenue divided by ad spend, usually shown as a multiple like 3x or as a ratio. It tells you whether paid traffic is profitable before other costs are considered.
Example
$1,000 in ad spend that generates $4,000 in revenue is a 4x ROAS.
Why it matters
A funnel with weak conversion rates can make even cheap traffic unprofitable — ROAS is the number that reveals that fast.
