You should focus more on the product, you should test new products before selling in large quantities, because if you don't test, you will lose a lot of money if you only focus on the old product without changing.Compared to last year, this year I have to spend 3 times more heavily than last year on advertising costs but the results still cannot be achieved like last year. Does anyone have any way to help me fix it?
