Seller A: The advertising fee has been increased by 3 times, there are only a few more orders, and the conversion card is at around 0.1. How can I fix it?
Seller B: The copy has been changed N times. They are all 'good material' and 'excellent quality'. Users don't even read it, and the detail page bounce rate is very high...
Seller C: I took 8 photos of the main image, and the number of hits hasn't been more than half that of others, so all the traffic is going to be wasted!
