I recently updated my Shopify theme and learned that Shopify now injects JSON-LD automatically for product pages. In the past, I created Schema markup for my products by creating a snippet, which was then rendered on product liquid files.
The new automatic Schema injection covers a lot of ground. However, I am finding that there are still bits of information missing that are important for my Google Merchant Listings.
What is the best practice for supplementing the pre-existing markup? I was thinking of once again using a snippet file, which would be rendered on product liquid files, but worry it would create a conflict of interest.
