Policy
MEDIUMMerchantReturnPolicy returnPolicyCategory uses valid Schema.org enum
When present, `returnPolicyCategory` is one of MerchantReturnFiniteReturnWindow / MerchantReturnUnlimitedWindow / MerchantReturnNotPermitted (bare or schema.org URL form). An invalid category is silently dropped — your policy looks present in the source but never renders in Google's return-policy rich result.
What this check looks for
We accept either the bare enum name (`"MerchantReturnFiniteReturnWindow"`) or the full schema.org URL (`"https://schema.org/MerchantReturnFiniteReturnWindow"`). Any other string — including freeform values like `"30 days"`, lowercased enum names, or typos — is rejected because Google's rich-result parser drops them silently.

How to fix it
Use a valid Schema.org returnPolicyCategory enum value
Shopify
Developer- If you hand-roll the JSON-LD in `sections/product.liquid`, swap any prose category string for the schema.org URL form.
- If you rely on Shopify Markets, confirm the emitted JSON-LD uses the schema.org URL form by viewing source on a PDP.
BigCommerce
Developer- Edit your product template's MerchantReturnPolicy block: replace the category string with `https://schema.org/MerchantReturnFiniteReturnWindow` (or the other two valid values).
WooCommerce
Developer- Yoast/AIOSEO MerchantReturnPolicy add-ons emit the schema.org URL form by default — confirm in browser view-source.
- If using a custom snippet via `woocommerce_structured_data_product`, swap prose values for the schema.org URL form.
Custom / headless
Developer- Use one of the three valid enum URLs (or bare names) — strict spelling, case-sensitive.
"hasMerchantReturnPolicy": {
"@type": "MerchantReturnPolicy",
"applicableCountry": "US",
"returnPolicyCategory": "https://schema.org/MerchantReturnFiniteReturnWindow",
"merchantReturnDays": 30
}The spec it's pinned to
Google return-policy SD — returnPolicyCategory enum
Google's return-policy spec recognizes only MerchantReturnFiniteReturnWindow, MerchantReturnUnlimitedWindow, and MerchantReturnNotPermitted as valid `returnPolicyCategory` values. Anything else is dropped from rich results.
