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.
