It will.

First, in the pre-sale state, since the product cannot be delivered immediately, the arrival time cannot meet the buyer's expectations, which will reduce the conversion of the page.

Second, I believe everyone will evaluate during the promotion of new products. The principle of evaluation is that the buyer can only increase the authenticity and security of the evaluation to a certain extent if the evaluation is made one week after receiving the goods. According to the previous logic, assuming that the new product is put on pre-sale on December 28 and available for sale on January 5, the buyer evaluates and purchases it on the 28th, Amazon ships it on the 5th, the buyer receives the goods on the 8th, and can only leave a review on the 15th. Doesn't it mean that the product has been in a state of no comments for 15 days before the promotion? And because it is in the pre-sale state in the early stage and there are no comments, the conversion rate of the page will be greatly reduced. There are not enough natural orders to support the conversion of the page. Then the previous promotion efforts are almost wasted?

Third, I have heard of a theory before that the inventory quantity and the number of warehouses where the inventory is located will affect the keyword ranking of the product. If the product is in the pre-sale period, the keyword ranking will be lower. Does it take more effort and money to promote new products during the pre-sale period by using free reviews or reviews to boost keyword rankings?
