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. 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.
The development of digital marketing, during the 1990s and 2000s, changed the way brands and businesses use technology for marketing. As digital platforms became increasingly incorporated into marketing plans and everyday life, and as people increasingly use digital devices instead of visiting physical shops, 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, 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.The extension to non-Internet channels differentiates digital marketing from online marketing.
