With so many different types of metrics available to marketers, it’s important to know which ones are the most important. Considering that marketers are spending lots of money on campaigns, the most worthy analytics should tell marketers which campaigns are bringing them the most return on investment (ROI). So for example, instead of looking at how many likes a post has received, it may be more important to see which post was the most effective in turning likes into sales. With that information, you can focus your marketing dollars on the right content.
