Start with the following points: where are the users, how to locate them, and who are the users who enjoy the battery?
So, what do users care about? How to impress users? Keep users interested?
Find the above problems and propose specific solutions:
For example, express delivery is the main user, so contact the express delivery company directly.
For example, the general public are users, so what are their channels for obtaining information?
In short, positioning core users-studying user habits-promoting users-forming transactions on the spot.
I hope it will be enlightening.
