Attributes are characteristics of products that make them distinct from other products.
Examples: size, color, functionality, components, and features that affect the product.
Attributes can be assigned to different product types as needed
Note: You may have a situation where you and attribute to show on the variant/SKU level and not the variable/parent level.
Attribute Groups are a collection of like attributes grouped together.
Example: A “Logistics Data” attribute group will contain all product logistics data like assembled width, carton/pallet level height, and assembled length
Attribute groups can be assigned to certain product levels the same way as single attributes
Note: If a product type in your attribute group is not the same as the assigned product type as your attributes it will not show up on the product page.
