The Internet has changed business, the way products are marketed, and the marketing landscape. To be successful in this new “marketing world,” business people need to understand how digital technology affects marketing and learn how to apply the fundamental principles of marketing to this new environment.

There are several online courses that can help you get started in this growing field of work. These classes will introduce you to the basics of digital marketing, helping you gain the skills you need to succeed.

For a high-level introduction to the subject, try Coursera’s Digital Marketing Specialization, which consists of six courses that you can complete at your own pace. The course is free to access, and each module features bite-sized video tutorials, making it easy for you to pick up the basic concepts of digital marketing.

Alternatively, if you want to take your learning to the next level, consider taking a mentor-led full-stack digital marketing certification program. These programs offer a blend of online learning with regular video calls with a mentor and real-world projects to hone your skills.

You can also opt for a more specialized digital marketing program at the University of Illinois, which offers an affordable and accessible certificate in this area. The program focuses on developing marketing strategies through digital channels, understanding consumer behavior, and conducting data analysis.

Another excellent option is Springboard, an online mentor-led certification that takes a more hands-on approach than many of the other options on this list. Here, you’ll work with a marketing professional and a community of peers to hone your skills and prepare for a career in digital marketing.

The course covers topics like social media, search engine optimization (SEO), and email marketing. In addition, students will create a digital marketing portfolio and receive career coaching.

This is a great way to get your feet wet in the digital marketing world, especially if you don’t have time or money to commit to a full-scale program. You can take this course at your own pace, and you can always stop the program if you feel that it’s not right for you.

Finally, for those of you looking for a longer-term commitment to your digital marketing education, the University of Illinois offers an online Certificate in Digital Marketing. This course combines three sequential courses and a capstone project to build an advanced foundation in digital marketing.

In addition to the online learning, students receive support from a digital marketing career coach who helps them prepare for job interviews and review resumes. This option is for students with an undergraduate degree who are interested in getting a head start on their digital marketing career.

You can also learn the fundamentals of digital marketing through a free online course at HubSpot, which is an online inbound marketing company. This is a 40-hour course that you can finish at your own pace, and it’s easy to earn official certification from HubSpot after you complete the lessons.
