      Implementation steps

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

      Common errors and fixes

      FAQs

      Should I include addenda?

      If addenda are listed on the page, update the CreativeWork description and include dates in the FAQ.

      How do I show multiple bid packages?

      Use separate CreativeWork entries or separate stack pages per project to avoid mixing scopes.
