As travel costs are high and sales can be less direct to track, I leave this to the end so you can establish yourself via less expensive channels while ensuring you’ve got the best product for success. If you get to this stage, you can pretty much go anywhere and close deals
From there you can scale by investing more in each of the channels to grow your sales.

Basically, now is the time when user are more adhere to online platform. So, digital marketing affects more to human resulting to be more productive as compared to traditional marketing.
