It depends on the mix, the marketing mix. Today, modern facets of marketing are an indispensable tool for digital marketers: Affiliate marketing, search engine marketing, online advertising/PR, e-mail marketing, mobile marketing and of course social media marketing.
Combined with classical marketing, as well as with online and offline communication, marketing opens the way to markets, customers, buyers, follower and various users.
Marketing, advertising and PR are digital, whether for a consumer product or for an "opinion product", such as political parties. Without practical knowledge of classic marketing and communication instruments, however, one can quickly lose one's bearings in the thicket of digital marketing. Success comes to those who move "above" and "below the line".
