for product_type, use the latter format; e.g.

Appliance Accessories > Range Accessories > Range Receptacles


excessive or non-standard capitalization anyplace in submitted

(feed) data violates the guidelines, is generally not allowed and

may trigger a disapproval or simply lower overall quality.


for the google_product_category attribute, all submitted

taxonomy values must be exactly as google defines; e.g.

Apparel & Accessories > Jewelry > Watches

Home & Garden > Kitchen & Dining > Kitchen Appliance Accessories

Home & Garden


both attributes should appropriately categorize the physical item;

importatnly, the values may also be used to group items for bidding.


unique-product-identifiers are the (global-trade-data) attributes

gtin, brand, mpn -- all global-trade-data must be assigned by the

brand-manufacturer (not merchants) and should be submitted as

assigned using plain (ascii) text with no special symbols or marks;

e.g. Apple, MC343LL/A, 885909194322, IBM, Sony, etc.
