What is Channel-Specific Attribute Requirements?

Channel-specific attribute requirements, often called marketplace attribute requirements, are the product fields, allowed values and formats that each sales channel demands before it accepts or shows a product. Google Shopping, Amazon, Zalando and your own webshop each have their own list. The requirements usually depend on the category. Google Merchant Center needs an ID, title, description, link, image link, price and availability for every product, a GTIN where one exists, and color, size, gender and age group for apparel in many countries. Marketplaces add their own category-specific fields and value lists, such as a fixed list of color names. This differs from your internal attribute model, which describes products your way; the channel requirements describe what each channel accepts. You can test a feed against Google's rules with the free Google Shopping feed checker.

Why Channel-Specific Attribute Requirements matters for e-commerce

A product that misses a required attribute is often rejected outright or shown in fewer searches and filters. On marketplaces, missing category attributes also mean your product does not appear when shoppers filter by size, material or compatibility. Because every channel asks for something slightly different, teams that sell on several channels need a way to see, per product and per channel, what is still missing. Without that, the same fix is made by hand in each channel's back office and the data drifts apart.

Frequently Asked Questions

They are the fields, value lists and formats a marketplace requires before it lists a product. They usually differ per category, so a dress and a drill need different attributes.

Keep one master attribute per fact, map its values to each marketplace's list, and track per product which required fields are still empty. Fix the gaps on your best sellers first.

Every product needs an ID, title, description, link, image link, price and availability. A GTIN is required when the product has one, and apparel needs color, size, gender and age group in many countries.

Usually not. One master attribute with value mapping per channel is easier to maintain than several fields that describe the same thing.
