I found interest in the business opportunities you’ve mentioned in your article. Most of them, Thank you. And, though, I never gave thought to most of them. However, there is inaccuracy in the “opportunities that didn’t exist 15 years ago.” I know because I was involved with them (e.g.,) eBay, online stores are commonly known as e-commerce, and affiliate marketing. Internet marketing (actually) started in the earlier 1990.s.
Simply put, digital marketing is the promotion of products or brands using electronic devices or the internet. It also includes text messaging, instant messaging, video, apps, podcasts, electronic billboards, digital television and radio channels, etc. Digital marketing uses multiple channels and technologies that allow an organization to analyze campaigns, content and strategy to understand what’s working and what isn’t – typically in real time.
Digital marketing is defined by the use of numerous digital tactics and channels to connect with customers where they spend much of their time: online. From the website itself to a business's online branding assets -- digital advertising, email marketing, online brochures, and beyond -- there's a spectrum of tactics that fall under the umbrella of "digital marketing."
