mohd,

You probably noticed that you don’t have to use a ton of tools to do this. We’re keeping it lean! Here’s a quick recap of the tools I’ve mentioned:

• Google Analytics: To track your campaigns and goals
• Google URL builder: To assign trackable links for your campaigns
• Sprout Social: To schedule your social media posts
• Customer LTV Calculator: To calculate the LTV of your customers

To measure and calculate ROI of online marketing and and social media marketing,you have to analyse data on how much you have invested in SM(Social media) and how much this has benefitted you,as compared to before .The calculations are as follows,

Social media ROI = (SM return – SM investment) / SM investment percent.

The ideal scenario is to have SM return higher than SM investment thereby signifying the efficacy of the SM campaign

you can just simply deduct your digital marketing budget to the acquired sales through the use of social and internet marketing.
