1- Bar Code (GTIN):
Since you don’t have a barcode (GTIN), set “Custom Product” to “True” to let Google know your items are unique.
2- MPN (Manufacturer Part Number):
You can leave MPN blank or create a unique identifier (e.g., your own code). For custom products, MPN isn’t required.
3- Missing Fields (Age Group, Color, Gender):
Yes, these fields need to be filled out for Google Shopping to approve your products:
Age Group: Select one like “Adult” or “All Ages.”
Color: Specify the color of each product.
Gender: Indicate “Unisex,” “Female,” or “Male.”
4- Bulk Update Method:
Use Shopify’s bulk editor or CSV export/import to update multiple products at once for fields like age group, color, and gender.
5- Feeds Tab Missing Issue:
If “Feeds” is not visible under products, it may mean you’re not using an app like Google Channel on Shopify. Install the Google Channel app from the Shopify App Store to manage Google product feeds.
