Digital marketing is the use of online channels, electronic devices, and digital technology to promote a business, person, product, or service. Social media, email, pay-per-click (PPC), search engine optimization (SEO), and other forms of digital marketing are just a few examples.
There are four major types of digital marketing. Each has its importance and plays a vital role in boosting any business. One person shouldn't be reliable on one strategy. All the four types should be used smartly to make optimum use of them.

10 Digital Marketing Fundamentals Every SEO Pro Should Know
