Hello, we are having trouble getting our Yotpo reviews to populate across Google because our Yotpo Catalog is using parent product urls and our Google Merchant feed is being sent and using full url with the variants (as provided by the Google sales channel app in Shopify). The solution we were given from Yotpo (who has said they can't change their feed to use the full url with variants) is to add the Spec SKU of the product as item group id in the Google Merchant feed. Again, they've said this should be done on the Product Feed itself. Can anyone help advise on how the Item Group Id for each product can be added to the Google Merchant Feed that is being populated from Content API? Within the Google Shopify app, I don't see any edit fields available to resolve this.
Thanks in advance,
You can not modify the group id in the free shopping app you are using. This app is basic and works as is.
If you want advanced features you need to use a paid data feed management tool.
However there are other ways to achieve the result you are looking for.
Use supplement feeds, ie create a spreadsheet to overwrite the primary feed. More info: https://support.google.com/merchants/answer/7439058?hl=en
Or use feed rules: https://support.google.com/merchants/answer/7450276?hl=en
Make sure the item group id is identical for all relevant variants, so make sure you first read: https://support.google.com/merchants/answer/6324507
Generally how Google matches reviews, is by ID, Brand, MPN and GTIN, so I recommend you correctly update these fields. However ID can not be changed in the feed with this app, but you can with other apps.
I help all merchants with these issues, feel free to contact me on my website.
Alternatively, the cheapest option with the ability to change the ID (not item_group_id) is https://apps.shopify.com/google-shopping-feed
Then to change everything without any limitations, I use DataFeedWatch
