You should consider pursuing a short-term online course in Digital Marketing. By short-term, I mean around 6–8 months, which is usually enough to build a strong foundation and practical understanding of the field. Regardless of your current knowledge level, starting from scratch is perfectly fine—especially since most reputed courses guide you step by step through SEO, social media, email marketing, content creation, and campaign management. The reason why it's better to go for a short term course for something like Digital Marketing is because you at the end need to exert yourself  practically rather than only being immersed in the theoretical side of things.  There are in fact no eligbility criteria at all besides the willingness to work and owning a good internet + System to work on. At the end of the day Digital Marketing is a very practical based life skill.  This goes well even with your long gap.

I would always recommend choosing a course that includes mentorship, hands-on projects, and live campaign experience, as these make it much easier to grasp and apply what you learn in real-world scenarios. From my experience, IIM SKILLS offers one of the most well-structured Digital Marketing courses with placement assistance and live demo classes as well. Definitely worth checking out
