Frequently Asked Questions
What is ROAS?
Return on Ad Spend (ROAS) measures the revenue generated for every pound spent on advertising. A ROAS of 300% means you earn £3 for every £1 spent.
What's a good ROAS?
A good ROAS varies by industry, but generally 400% (4:1) or higher is considered excellent. Break-even is typically around 100-200% depending on your profit margins.
How accurate are these projections?
These are estimates based on your inputs. Actual results may vary due to market conditions, ad quality, landing page performance, and other factors.
