Frequently Asked Questions

How should I allocate my advertising budget across channels?

Start with 60% on proven high-performing channels, 30% on secondary channels, and 10% for testing new platforms. Adjust based on conversion rates, cost per acquisition, and ROI data.

What's a good return on ad spend (ROAS)?

A good ROAS varies by industry, but generally aim for 4:1 or higher (400% return). E-commerce often targets 3-4:1, while services may aim for 5-8:1 depending on profit margins.

How do I calculate cost per acquisition (CPA)?

CPA = Total Ad Spend ÷ Number of Conversions. Compare this to your customer lifetime value (CLV). Your CPA should be significantly lower than CLV for profitable advertising.

When should I increase my advertising budget?

Increase budget when ROAS exceeds targets, you're reaching audience limits, or have successful campaigns with room to scale. Always test incrementally and monitor performance metrics.

How do I track cross-channel attribution?

Use UTM parameters, conversion tracking pixels, and analytics platforms like Google Analytics. Consider first-click, last-click, and multi-touch attribution models for comprehensive insights.
