ROAS or CPA? Which Metric Should You Optimize For?
AdsOptimize EkibiJune 14, 20265 min read
Two Metrics, Two Different Questions
ROAS (Return on Ad Spend): "How much revenue did I get back for each $1 spent?"
CPA (Cost per Acquisition): "How much did I spend to acquire a customer?"
When Is ROAS More Important?
- E-commerce businesses
- When LTV is predictable
- For immediate sales-focused campaigns
When Is CPA More Important?
- SaaS / subscription models
- High LTV but low first-purchase value
- Lead generation
Look at Both Together
Looking at only one metric is misleading. The AdsOptimize dashboard shows ROAS, CPA, and LTV-CAC ratio side-by-side for every campaign.
