There is an advertising banner at the top of the home page of the post bar, which has a certain income, and this is not how much you spend a month, but many companies will change different advertisements at different bidding times. You can have a look at it when you refresh it.
In addition, Post Bar is not for profit, but to create some interactive areas for netizens to enhance Baidu's popularity, so that there will be certain benefits when promoting other products. Just as Baidu knows, it also knows that all posts in Post Bar will be included by Baidu, so some businesses will work hard here.
hope this helps
I wish you all a happy journey on Baidu's platform.
Baidu knows that the professional team will answer your questions.
Hope to adopt! ! !
