If they try to adjust advertizing independently, means they make a huge mistake because hardly they will manage to make it most qualitatively. It is far better to employ the professional expert.
Hiring the professional expert of advertisement is the best way to plan the strategy on choosing when to advertise and when to pause the advertisement.
The team itself can make and come up the best strategy for their marketing promotions for the project. A good and great marketing straregy does not depend on the one that will make it even it an expert or not because what I believe is that, it is whether you know what your clients and supoorts will be liked and prefer that you will be able to gain them from their heart and engage themselves in here accordingly.
