Keyword attributes explained

Overview

The table below explains the keyword attributes that sellers encounter when managing product listings. Most of the keyword attributes require valid values, which can be found in the Browse Tree Guides (BTGs). The attributes specific_uses_keywords, thesaurus_attribute_keywords and target_audience_keywords are primarily used in the U.S. and are being phased out. Free text can be input for generic_keywords and subject_keywords. Subject_keywords should only be used for the Media products. You do not have to populate platinum_keywords as they are now redundant.

How is this data used?

Sellers populate attributes and Amazon uses the data to help the customers to find products. For example, Amazon uses the data to generate search results for customers keyword searches. The data is also used to automatically assign products to browse navigation, another way in which the customers find products. For example, the browse assignment query of “style_keywords:sport-sandals” assigns the products that have a style_keywords value of sport-sandals to the Sports Sandals browse node.

Should I use the drop-down list or free text?

On the Keywords tab that the sellers see when adding or editing listings in Seller Central, the sellers can either select a drop-down value or enter free text. Free text must match with a valid value listed in the BTGs, so that it is possible to use the data in browse queries. Amazon does not publish the full list of valid values; rather, we direct sellers to the BTG that corresponds to the product category in which they sell, in order to ensure that they focus on the values that are relevant to them.

Length Limits

Search Terms (generic_keywords) should be less than 250 bytes long (read more). If it exceeds the limit, the attribute is completely ignored by Amazon Search.

For other length limits in the table above, if the limit exceeds, Amazon Search indexes up until the length limit and ignores any excess.
