58 What can be done to accurately promote arbitrary deduction in the same city? The click rate is as high as 160%! ! !

I have been a member of 58 city for 6 years, and the annual advertising fee is 70,000-80,000. To be honest, it was ok at first, but now it is very poor, not as good as Baidu. Baidu also deducts fees, but the source can be checked clearly, but 58 cities spend more than 300-400 every day. Somehow, you clicked offline as soon as the advertisement was opened. Some peers click maliciously, but the speed is very strange. In addition, in order to make money this year, 58 cities are also struggling.
