At present, the network promotion I know is more effective in 58 cities, 360 fairs and baidu promotion. I work in the same city as 58, and now my promotion should be around 8000 a year. Compared with 6800, there will be a certain price increase in a few years. As far as I know, I don't lose money if I do it for a year, and I will come back if I can take a few orders a year. I've seen a lot of them, too. They all work well. After many years, I think I can still make money. 58' s search volume and entrance are still quite a lot, but also more professional, mainly local life services. What Baidu knows best is that it costs a lot of money to do a good job, maybe tens of thousands or even hundreds of thousands, but it will be good to spend more money. It is suggested that if it is not a big project, such as a construction project, it should not be done, and the investment is too high. As for other platforms, I won't answer if I don't have much contact. It's best to get to know them better with the salesmen of the platform company and make a good comparison. Each platform has its own advantages, and I hope it will help you.
