When it comes to choosing the validity period of a product when launching a product, we all know that there are two days to choose from, 14 days and 30 days. Many friends choose 30 days by default. Here I suggest you choose 14 days, because when the product is about to be sold out, the exposure will increase a lot, and it will be easier for buyers to find us.
So if you choose 14 days, you will get two high-exposure opportunities a month. If you choose 30 days, you will get one opportunity a month. Therefore, when choosing the product validity period, it is recommended that you choose 14 days.
