There are plenty of options for the best digital marketing course in Kolkata, but I think the bigger question is what actually makes one course useful.
Is it the number of modules? The certificate? Placement assistance? Course duration? Or the amount of practical work students get to do?
For someone starting out, I would probably look at the curriculum, live project experience, trainer involvement, analytics training and whether students get to work with actual marketing tools.
A certificate can show that you completed a course. Practical work can show what you can actually do.
What would you consider the most important factor when choosing a digital marketing course?
