Implementation steps

Start from your live product detail page content; ensure titles, prices, and availability match the page.
Embed one JSON-LD script in the head or just before the closing body tag using the combined example as a template.
Fill shipping details for each region you serve and keep them aligned with on-page shipping tables.
Attach your canonical MerchantReturnPolicy URL and keep the policy text in sync with Merchant Center.
Add 3–6 FAQs that address purchase blockers (shipping, returns, compatibility) and keep answers consistent with visible content.
Validate in the Rich Results Test and revalidate after price/availability/policy changes.

Common errors and fixes

Missing currency or availability: ensure `offers.priceCurrency` and `offers.availability` use ISO currency codes and schema URLs.
ShippingDetails missing destination or transit time: include `shippingDestination.addressCountry` and `deliveryTime.transitTime` with units.
MerchantReturnPolicy not linked: reference it from the Offer via `hasMerchantReturnPolicy` and provide a stable policy URL.
FAQ answers don't match the page: keep FAQ content identical to visible answers to avoid review or manual actions.

FAQs

Can I include a paid upsell?

Yes. Link the upsell in offers.url or the page body. Keep the free tool URL and pricing at 0.00 for the free experience.

How do I handle localization?

Localize text and currency on-page and in JSON-LD; adjust priceCurrency accordingly if you localize offers.
