FAQs

What is a good ROAS?

Good ROAS depends on profit margins. With 50% margins, need minimum 2:1 ROAS to break even. Target 4:1 or higher for healthy profitability. High-margin businesses can succeed with lower ROAS.

How do I improve ROAS?

Improve targeting to reach high-intent customers, optimize ad creative, improve landing pages to increase conversion, increase average order value, and reduce wasted ad spend on poor performers.

ROAS vs ROI: what's the difference?

ROAS measures revenue return from ad spend. ROI measures profit return including all costs (COGS, overhead). ROAS is simpler to track, ROI gives true profitability picture.

Should I maximize ROAS?

Not always - maximizing ROAS often means reducing spend to only absolute best performers, which limits growth. Balance ROAS optimization with volume goals for sustainable scaling.
