The main goal behind any type of marketing effort is to reach maximum number of potential clients and researchers / marketers have always been trying to find out an answer to this question i.e. how many people have viewed or have been impacted by their marketing efforts. With conventional marketing techniques, it is never fully possible to judge that how many people actually saw your billboard / television ad, how many fully read your newspaper / flyer post, who listened to your radio broadcast and then how many out of those actually became customers.
With the right metrics based systems of Digital Marketing it is easily possible to view the figures on your online traffic, likes / followers of your social media profile, comments, messages and interactions with customers, correlation amongst these values with the actual buyers of your product and even the number of missed business opportunities. All these metrics help evaluate the Return on Investments (ROI) for a business. In addition, these ROI metrics also help a business in restructuring, rebranding and redefining their product to improve and become even more competitive.
