Return on Investment (ROI) is a vitally important measure for marketers and those who employ them. It’s a metric of the success of any advertising or marketing campaign, presented as a percentage of the investment made in that campaign.
Successful campaigns will experience ROI above 100%, which means that the campaign returned at least all of the cash that was invested in it. Failed campaigns will return less than 100%, which suggests that the campaign cost more than the revenue it generated.
It is possible to calculate the ROI of any campaign by dividing the goal completions by the amount of money invested to achieve the goal.
