What refers to how much revenue is gained versus how much was spent?
- Customer lifetime value
- Return on ad spend (ROAS)
- Linear budgeting
- Budget touchpoints
Explanation: Return on ad spend (ROAS) refers to how much revenue is gained versus how much was spent. ROAS is a performance metric that measures the effectiveness of advertising campaigns by evaluating the revenue generated in relation to the amount spent on the advertisements. It is calculated by dividing the revenue generated by the cost of the advertising, providing insights into the profitability of the advertising investment. Unlike customer lifetime value, which focuses on the total revenue a customer brings over their lifetime, ROAS specifically assesses the immediate return on investment for a particular advertising initiative. Linear budgeting and budget touchpoints are not directly related to the comparison of revenue and spending in the context of advertising effectiveness.
