The detail page is where customers view a product sold on Amazon. If you've shopped on Amazon, you'll probably recognise the product detail page. This is where customers can find all the relevant information about a particular item.
When multiple selling partners offer the same product, Amazon combines data from these various offers into a single detail page (so that we can present customers with the best experience possible). You can propose to include product information on a detail page, along with other sellers and manufacturers, and you can request that the page be reviewed if you think that the information is not correct.
When creating a product detail page, try to think about what would best help customers to find your products, find answers to their questions and make a purchase decision. Aim to provide customers with the best experience possible through concise, accurate and clear listings.
