Product matching helps you match your product to an existing listing. It then adds your offer information to that listing. If a product does not yet exist in the catalog, you can create a new product detail page.
Good product matching directly benefits you. When you match your product to an existing listing, you ensure that customers can find your offer.
You can make the most of product matching by appropriately classifying your products in the inventory files you upload to the website. When you upload your inventory listings, Amazon runs the data through our matching engine to link your products with the appropriate catalog entry.
A key feature on Amazon is that the same product can be sold by multiple sellers. One seller "wins the Featured offer," while all other sellers appear when the customer clicks "More Buying Choices." The Featured offer winner is determined by a combination of product availability, retail price, and other factors. See The Featured offer for more information.
When customers find a product, they see the product detail page, which includes the Featured offer ("Ready to Buy") and a "More Buying Choices" box (if several sellers offer the same product).
When multiple sellers are selling the same product, the customer can view a list of offers.
Here are some possible errors that might occur when matching a product or creating a new product entry:
In this case, we cannot determine which entry should be matched to your product. Contact us about this error.
The product data, such as the manufacturer name and manufacturer part number, is not distinctive enough. For example, you submitted a manufacturer name and manufacturer part number that appears to match more than one product. Enter more specific information to find a match.
A product match was found, but you already have a different SKU associated with it. This can happen if you re-used a SKU previously associated with a different product. To fix this problem, delete the SKU and resubmit the product data.
If you submit a product, but you do not include the required fields for that product type, you will get an error message and the listing will not be added to the catalog. This ensures that wrongly classified or cataloged products do not appear on the live website. To resolve this problem, re-submit the product with all the required data.
Use a standard product identifier when submitting your products. The three top standards are ISBN, UPC, and EAN. This is the most important and reliable piece of data in the matching process.
The manufacturer part number is different from the SKU. The manufacturer part number is the standard by which manufacturers identify their products.
If you are creating child products for a variation, each child item must have the correct and unique UPC or manufacturer part number.
This data is almost always required to create a new product.
For example, product dimensions such as height, width, and weight should be specified in the Height, Width, and Weight attributes. Do not use general purpose merchandising fields for these values.
Do not include merchandising information in the item name. Use the product description and the bulleted list for adding merchandising details. For example, do not include "Reduced Price" in the name of the article.
If you must change your SKU for a product, do not re-use or recycle old SKUs. Issue a new SKU for the item, and then re-assign the product to the new SKU.
If you create parent and child products for variations, the product data for the parent product should contain only data that is common to all child products. This includes Item Name, Product Description, Featured Bullets, and so on. Standard identifiers such as UPC, EAN and manufacturer part number are unique for each child product. Do not copy these values into the attributes for the parent product.
