Frequently asked questions · Performance Marketing
Important questions before deciding.
Clear answers prepared for people, search and answer engines.
What is the difference between ROAS, contribution margin and profit?+
ROAS compares attributed revenue with media spend. Contribution margin removes variable costs. Profit also includes fixed costs, taxes and other expenses, so ROAS alone does not prove profitability.
Is the calculator CAC a complete CAC?+
No. It is media CAC only. A complete CAC also includes fees, team, technology, production, commissions and other acquisition costs.
How does FGX recommend media investment?+
We consider the objective, history, audience size, sales cycle, margin, commercial capacity and the minimum volume needed to learn. Investment is an operating hypothesis, not a return guarantee.
Can campaigns connect to CRM and offline sales?+
Yes, when tools, permissions, consent and data quality allow it. We document the integration and attribution limits.
How long does a campaign take to show results?+
There is no universal period. Learning depends on demand, spend, conversion volume, offer maturity, creative quality and sales cycle.
How do you handle attribution and privacy?+
We document events, data sources and limitations, use consent-compatible configurations and read analytics, platforms and CRM together.
