I was recently scrolling through 上 and found a few marketing cases that have been pretty successful there.

One is a bar owner who posts jokes on 上 every day—his traffic is also not bad, but he mainly complains about people and things inside certain bars.
Another is a restaurant owner who has set a few billiards tables in his restaurant. People come to challenge him—if they win, he waives the bill; if they lose, they pay at the original price… and his traffic is also very good.
Now, if you’re running offline stores and not doing online promotion, you really don’t have much to work with—you’re just not that capable.
