Saurabh: Do you mean what budget you (or your organization) should set for digital marketing training program? If you search on Google you will find a number of digital marketing courses including a lot of good quality free content. However, in our experience over last 6.5 years, the real value people find in our digital marketing certification programs is through following elements:
Practical assignments, exercises and projects across various areas of digital marketing
Live sessions with industry experts including Q & A
Research based digital marketing internship
Global & local digital marketing case studies
You will find it worth paying Rs 50k/participant for such hands-on master level certification program. Hope this helps!
