There are many ways in which we can measure the return on investment. For example, if you are running Google ads or Facebook ads, their inherent reports mention various points of data – such as the total cost incurred, the number of leads generated etc., which can be used to calculate ROI. Furthermore, we also heavily use Google analytics that provides a comprehensive understanding of where the traffic is coming from, the actions they take on your site, the amount of conversions happening etc. This data is crucial in determining the final ROI of your digital marketing campaigns.
