Where Digital Marketing is unable to play its Role?

The another answer could be that there is no use of marketise any product digitally unless it realizes its cost or expenses. Furthermore sometimes most of the people don't believe in online business.They prefer shopping and physical verification rather than either ordering via phone or through any other online channel, i.e website and transferring money online etc. Here these sort of ways loose their trustworthiness.
