Thank you for posting your query!
As you are already coming from digital background and possessing ample experience then you can easily switch to any field related to digital marketing like SEO, SEM, SMM or even digital marketing as a whole. If you have already made your mind to go for SEO, then you can get a senior or managerial position provided that you are qualified in Digital Marketing. If you talk about digital marketing then each segment of digital marketing is dependent on another. Talking specifically about SEO, the score and reach depend upon the content, who your target audience are and the way you communicate with them.
Moreover, any company will prefer a candidate who is capable of more than one specialization. And That is what the CDMM course is all about. After opting for the course, you will get the ability to unlock your potential, gain expertise in diversified approaches of Digital Marketing and unlock the opportunities as a Digital Marketer.
Hope I answered your question.
