Assess growth through customer demand, acquisition cost and contribution. Use these resources to connect channel decisions with the economics of the business.
For an acquisition decision, read customer acquisition cost alongside contribution margin. For retention investment, compare customer lifetime value with observed customer cohorts. If you are considering a launch, start with the go-to-market explanation and the market-entry guide so demand and operational readiness are assessed together.
Write down the period, customer group and cost basis behind the question. A strong revenue ratio can coexist with weak contribution, and a forecast of repeat value can differ from observed behaviour. Use the linked resources to align the commercial definitions before choosing a channel budget or growth plan.
Use the linked guides and service pages to understand the scope, then describe your business challenge. A definition or example explains an approach; it is not a diagnosis of your own implementation.
Reference
Contribution margin is the money left from revenue after the variable costs included in your definition. It helps show whether more sales leave more money to cover fixed costs and profit.

Customer acquisition cost (CAC) is how much you spend to acquire a new customer under a stated cost definition. It is different from cost per order because returning customers can place more orders.

Customer lifetime value (CLV or LTV) estimates how much value a customer generates over the relationship. State whether you mean revenue or contribution, and whether the figure is observed or forecast.

A go-to-market strategy explains who you will sell to, why they should choose you, how you will reach them and how you will deliver profitably. For ecommerce, the plan connects marketing with pricing, the store and operations.

ROAS compares attributed revenue with advertising spend. Profitability requires a wider cost definition. A higher ROAS can accompany weaker business performance when discounts, product mix, returns or other costs change.
