ROI= $$$$$

The acronym ROI stands for return on investment, which equals to the gains of your investments minus its costs divided again by the cost. It is usually easy to measure the ROI for commodities but it takes more effort to analyze whether a social media campaign is effective or not. First of all, to understand if we increased gains using online social networks we have to know where we started from. That is why the first step should be to measure on a chart where we are starting and compare the before and after social media situation. The change between before and after is usually named delta. The second step should be to establish a timeline monitoring what we constantly do and track it online. We are going to lay out the sales, the number of transactions, the number of old and NEW customers. Last but not least, we should measure the frequency of transactions, how many new and old consumers we reached and how much they spent on every transaction!
