The amount of inventory reflects the stability of the seller’s operation and affects the ranking of the product. According to the logic of Amazon’s A9 algorithm, if the inventory of a product is too small, considering the stability of the system display, its exposure opportunities will be reduced and the product ranking will be relatively low.
Therefore, if funds permit, sellers should combine sales expectations, stocking cycle, delivery time and other factors to prepare as much inventory as possible to avoid ranking decline and out-of-stock due to too little inventory.
In terms of inventory quantity, we must remember that out-of-stock is one of the main reasons for a significant drop in product weight (the other main reason is bad reviews), which should be avoided as much as possible.
