You can use Shopify applications such as "Google Shopping Feed" or "Flexify" to help you generate and manage these feeds.

Configure Google Merchant Center:
Create a Google Merchant Center account if you don't already have one.
Set up multiple feeds in Google Merchant Center, one for each language and country combination. This ensures that ads are displayed correctly in different markets.

Link Shopify with Google Merchant Center:
Use the tools provided by Shopify to link your shop with Google Merchant Center. This usually involves adding your Google Merchant Center ID in Shopify and confirming the connection in Google Merchant Center.

Upload and Verify Feeds:
Upload product feeds to the Google Merchant Center and make sure they comply with Google's policies.
Google will check feeds and products to make sure everything is in order.

Monitoring and Optimisation:

Regular Updates:
Keep your feeds regularly updated to reflect any changes in your products, prices or inventory.
