Marketing experts can use any marketing that uses electronic tools to deliver a promotional message and measure its impact through your customer journey. Digital marketing usually refers to online marketing campaigns on computers, phones, tablets or other devices. This can take many forms, including online video, display advertising, search engine marketing, paid social advertising, and social media posts. Digital marketing is often compared to “traditional marketing” such as magazine advertising, billboards, and direct mail. The funny thing is that television usually gets associated with traditional marketing.
