In the past two years, the US site has had a product pre-sale function. After the product arrives at the FBA warehouse and is received, it is necessary to carry out inventory turnover between different warehouses before it can be converted into saleable inventory for sale. During the inventory turnover period, the product can still be in a saleable state, but the text displayed on the front desk is: In stock on January XXX, 2021, which takes as little as 3/5 days and as much as 10 to 15 days, especially during the American holidays and when the warehouse is short of staff, the time is longer.

Assuming that the product is new and in the new product period, if it is promoted in the pre-sale state, is it a waste of the new product period?

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 buyers can only increase the authenticity and security of the evaluation to a certain extent if they leave a review one week after receiving the goods. According to the previous logic, suppose the new product is put on pre-sale on December 28th, available for sale on January 5th, the buyer conducts evaluation and purchase on the 28th, Amazon ships the product on the 5th, the buyer receives the product on the 8th, and can only leave a review on the 15th. Doesn't it mean that the product has no reviews for the 15 days before the promotion? And because it is in the pre-sale state and there are no reviews in the early stage, the conversion rate of the page will be greatly reduced. There are not enough natural orders to support the conversion of the page, and 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 at the bottom. Does it take more energy and money to promote new products during the pre-sale period and use free reviews or reviews to promote keyword rankings?
