If your Shopify products aren’t syncing properly with Facebook Ads Manager—like some are missing or showing up in the wrong categories—it’s almost always a formatting or setup issue with how the data is pulled from Shopify into Facebook’s catalog.
Here’s what might be going wrong and how to fix it:
1. Product info is incomplete
If your products are missing important fields—like titles, descriptions, SKUs, or GTINs—they may get skipped or misclassified during the sync.
2. Not marked as available for Facebook
In Shopify, each product needs to be marked as available in the Facebook & Instagram Sales Channel. If that’s not selected, Facebook won’t pull it in.
3. Variants don’t have proper details
If your product has size or color options, each variant should have its own SKU and image. Missing this can confuse the sync.
4. Wrong or missing categories
Shopify categories don’t always match what Facebook expects. Facebook uses Google’s product taxonomy, so it’s worth double-checking those fields if products look misplaced.
5. Currency mismatch
If your store’s currency doesn’t match what’s set up in your Facebook Business settings, it can cause some products to drop.
What You Can Do:
Go to Shopify > Facebook > Settings > Product Sync and check product availability and errors
In Facebook Commerce Manager, head to Catalog > Diagnostics to see specific sync issues
If you want more control, apps like Flexify or Data Feed Watch let you customize the feed
Try disconnecting and reconnecting the Facebook channel and re-saving your products to trigger a fresh sync
