Shopify products are assumed to be either in stock or out of stock depending on their inventory levels.
That’s usually good enough for most stores but sometimes you need more options. Especially with Google Merchant Center where you might be running ads for preorders.
Product availability options
By default JSON-LD for SEO will use the data from Shopify for your product’s availability. That will be either InStock or OutOfStock.
If you’d like to use a different option, JSON-LD for SEO supports all of the ItemAvailability options in Schema.org. At the time of this writing those are:
If you’d like to change the availability of an item to be different than the standard InStock/OutOfStock, here’s how.
1. Install a metafields tool
JSON-LD for SEO uses Shopify metafields to configure the availability. Metafields are a common way to store extra data about things that Shopify hasn’t built a user interface for yet.
Metafields tools are apps that let you create, update, and manage the metafields for your store.
Here’s a limited list of metafield tools, you can use any one you want because the end result will be the same.
2. Find your product
Using the tool, find one of your products you want to customize.
3. Create a new metafield
Once you’ve found the product with the metafield tool, you’ll want to add the following data. Let’s say you wanted to mark it as a PreOrder product, you’d set the value to PreOrder.
namespace: jsonld key: availability value: PreOrder type: string (some tools might not use the type field)
You can use whatever type you want from Schema.org’s list above. Just use the value (
PreOrder) and not the full url (
https://schema.org/PreOrder), JSON-LD for SEO will automatically add the url part for you
4. Test the new data
Once that’s done you can test the product in Google’s Structured Data Testing tool. You should be able to see the availability updated there right away.
Then you’ll have to wait for Google Search to recrawl and reanalyze the page. Once that happens, you should be good to go.
Reverting back to the regular product availability
If you need to revert back to the regular in-stock/out-of-stock availability, just find that metafield and delete it. JSON-LD for SEO will automatically revert back to the regular availability logic.
