Thanks for the invitation:
First of all, elevator projection advertisements generally target local merchants, so we first target the investment area—the local city.
Online promotion channels are divided into free and Paid channel
Free channel 1: Join some local advertising groups, merchant groups, etc., send group messages to gain customer flow
Free channel 2: You can use Baidu Tieba, Tianya Forum, Zhihu, Post on Weibo, Toutiao, etc., you can get free customer traffic
Paid channels: Baidu Information Flow, Toutiao, Weibo Fans and other related agents to place Internet advertisements
Hope to Thank you for your help
