Frequently Asked Questions
- What is a good ROI for marketing?
- A common benchmark is a 5:1 ratio (£5 returned for every £1 spent), equating to a 400% ROI. Exceptional campaigns achieve 10:1 or higher. Below 2:1 (100% ROI), profitability after overhead may be minimal.
- What should I include in the "cost" figure?
- Include all direct costs: media spend, agency/freelancer fees, creative production, software tools, and a fair allocation of staff time. Underestimating costs inflates apparent ROI.
- How is ROI different from ROAS?
- ROAS (Return on Ad Spend) measures revenue generated per pound of advertising spend and does not account for costs beyond ad spend. ROI is a broader profitability measure that includes all associated costs.
