Frequently Asked Questions
What is the maximum CPA I can afford on Shopify?
Max CPA = Sale price × gross margin − platform fees. At $50 sale price with 40% gross margin and 2% + $0.30 Shopify Payments fee: gross profit = $20, Shopify fee = $1.30, max CPA = $20 − $1.30 = $18.70. Spend less than $18.70 per acquired customer to be profitable.
What is a good CPA for Shopify ads?
CPA benchmarks vary by channel and product. Facebook Ads: $15–40 for most niches. Google Shopping: $10–30. TikTok Ads: $8–25 for impulse-buy products. A 'good' CPA is anything below your maximum CPA (profit per order). Calculate your specific max CPA first, then set campaign targets 20–30% below it.
How do I lower my Shopify CPA?
Three levers: (1) Improve conversion rate — same ad spend, more buyers; (2) Improve AOV — same CPA, more revenue per customer; (3) Better audience targeting — higher-intent traffic converts at lower cost. Improving conversion rate from 2% to 3% cuts your effective CPA by 33% with no change to ad spend.
