Can I hide the bundle from storefront search and search engines?
Yes, you can hide a bundle from storefront search and search engines. By default, bundles are linked to a display product.
Just create a new metafield for the display product with the following attributes:
- "namespace" : "seo"
- "key" : "hidden"
- "value" : 1
- "type" : "number_integer"
If you are using a Shopify app to power your storefront search, it's subjected to the setting of the app.
