Aditya: Thanks for sharing your concern. You are welcome to ask any kind of question here :).
I agree with you. A 1-2-3 day workshop is not sufficient to build skills/competency in digital marketing. While it can orient a person about digital marketing space, it can't replace a comprehensive, hands-on digital marketing course.
To share with you, we regularly conduct 2-3 day Digital Marketing workshops for organizations but as I shared, the objective of these workshops is completely different than the purpose we serve through our 6-month Digital Marketing Master Certification program.
