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.
