How These Metrics Relate
ROAS and CPA are inverse efficiency measures:- TikTok ROAS tells you how much revenue you earn per dollar spent (higher is better)
- TikTok CPA tells you how much you spend per conversion (lower is better)
- TikTok Ad Spend — your investment
- TikTok Purchases — conversions attributed
- TikTok Purchases Value — revenue attributed
Choosing the Right Metric
- Revenue-focused analysis: Use ROAS to measure dollar-for-dollar return
- Cost control: Use CPA to track acquisition costs against targets
- Campaign optimization: Compare both across ad sets to find efficient performers
