I am seeing similar product to ours listed in categories that are not listed in the taxonomy list.

Are these old or new categories?

Are these unavailable to our company?

Hi @AWF A,


Have you reviewed this Google Help File on product taxonomy and this Google Help File for categorize your products? 


Please take a look and see if it does not provide some great resources to you. Let us know if you need more help.


Kind Regards,

the left-hand-side category taxonomy lists on google-shopping
are not necessarily directly from google_product_category values --
the list is created automatically and dynamically by google from
various sources including product_type or google_product_category,
indirectly via title, and description, information derived from user's
searches and search-histories, and many other sources.


note that product_type may be used to include such exact taxonmy

values, using proper > delimited breadcrumbs; however, using such

exact taxonomy values within a title or description violate the policies,

so should never be used.

at one time, google exposed their shopping-search-api -- so the category's
probability-distribution could be inspected and seen to grow over time, as
more merchants submitted items of a particular category, search histories
accumulated, and google auto-generated facet-buckets for a category-list;
however, that api is no longer available and the internal details were never
fully articulated by google publicly.

that said, google has yet to publish exact details concerning their
left-hand-side lists -- despite being asked many many times before.
