What is the ROI of our paid digital marketing efforts?

Digital Marketing ROI is a measure of the profit or loss you generate in digital marketing campaigns.
According to the money you invested.
In other words, this measure tells you whether you deserve your rewards from your trading campaigns.
If you have a positive return on investment, it means that you can contribute more money to your payroll than you spend.
Proof of Digital Marketing ROI is important because without measuring this you are essentially marketing blind.
