ELI5: Explain Like I'm 5

Return on marketing investment

Return on marketing investment (ROMI) measures the amount of money you get back for every dollar you spend on marketing. For example, if you spend $1 on marketing and get $5 back, your ROMI is 5. It's important to measure ROMI to make sure your marketing efforts are leading to actual sales, so that you can make decisions about how to best use your money to get the most benefit.
