How it works
CPA (Cost per Acquisition) is the all-in cost to win one order via ads. It's the cleanest way to compare campaigns when basket sizes and AOV are similar. CPA should always sit below your contribution margin per order — else every ad-driven order loses money.
When to use it
Use CPA when you know your gross margin per order and want a hard cap for bid decisions. Max CPA = Gross margin per order. Anything above is unprofitable.
Frequently Asked Questions
What is a good CPA on Quick Commerce?▾
Depends on your AOV and margin. For a D2C snacks brand with ₹180 AOV and 35% gross margin, CPA ceiling is ~₹63. For Health & Nutrition with ₹450 AOV and 40% margin, CPA can go up to ₹180. There's no universal 'good' — it's relative to your unit economics.
How do I lower my CPA?▾
Three levers: improve listing conversion rate (OCR) through better images and pricing (most impact), tighten keyword match types and pause zero-conversion keywords, and concentrate spend on hero SKUs with proven velocity.
Is CPA the same as CAC?▾
CPA is often per-order; CAC (Customer Acquisition Cost) is typically per-customer. If 1 customer orders 1.5 times on average within 30 days, CAC = CPA ÷ 1.5.
Can I use CPA for bid decisions?▾
Yes — set max CPA caps per keyword based on your gross margin per order. Pause any keyword exceeding 2x your target CPA for 48+ hours.
