FAQs
What is a good CPA?
Good CPA is one significantly lower than customer lifetime value. Aim for CPA at 1/3 or less of LTV for sustainable profitability. This varies by business model and profit margins.
How do I reduce CPA?
Improve conversion rate through better landing pages, optimize ad targeting, enhance ad creative, improve Quality Score, test different offers, and remove underperforming keywords/audiences.
CPA vs CAC: what's the difference?
CPA (Cost Per Acquisition) is typically just advertising cost per conversion. CAC (Customer Acquisition Cost) includes all sales and marketing costs: ads, salaries, software, content, etc. CAC is more comprehensive.
Should I focus on CPA or ROAS?
Both matter. CPA is great for lead generation and consistent-value products. ROAS (Return on Ad Spend) is better for e-commerce with varying order values. Ideally track both.
