Digital marketing is the marketing of products or services using digital technologies on the Internet, through mobile phone Apps, display advertising, and any other digital mediums.[1] Digital marketing channels are systems based on the Internet that can create, accelerate, and transmit product value from producer to a consumer terminal, through digital networks.[2][3]

The development of digital marketing, during the 1990s and 2000s, changed the way brands and businesses use technology for marketing.[4] As digital platforms became increasingly incorporated into marketing plans and everyday life,[5] and as people increasingly use digital devices instead of visiting physical shops,[6][7] digital marketing campaigns have become prevalent, employing combinations of search engine optimization (SEO), search engine marketing (SEM), content marketing, influencer marketing, content automation, campaign marketing, data-driven marketing,[8] e-commerce marketing, social media marketing, social media optimization, e-mail direct marketing, display advertising, e–books, and optical disks and games have become commonplace. Digital marketing extends to non-Internet channels that provide digital media, such as television, mobile phones (SMS and MMS), callback, and on-hold mobile ring tones.[9] The extension to non-Internet channels differentiates digital marketing from online marketing.
