Add a JSON-LD script block in sections/main-product.liquid or a product-schema snippet that outputs the Product type with name, images, brand, sku, gtin, and an AggregateOffer containing per-variant Offer entries. Use Liquid json filters to escape values and validate the result with Google's Rich Results Test.

Point the canonical link tag to the base product or collection URL instead of variant or filtered URLs, and output noindex, follow robots meta tags when current_tags, filter, or sort_by parameters are present. This prevents parameter-heavy URLs from being indexed separately.

Yes, Shopify lets you customize robots.txt through the robots.txt.liquid template, where you can add Disallow rules and per-locale sitemap references. Hreflang tags can be generated by looping over shop.published_locales and outputting alternate link tags per locale.

No, the largest above-the-fold image should use loading="eager" and fetchpriority="high" because it is typically the LCP element measured by Core Web Vitals. Lazy-load only subsequent images, and always use the image_url filter so Shopify's CDN serves modern formats.

Outputting AggregateRating without genuine review data violates Google guidelines and can trigger penalties or loss of rich results. Only render the rating schema when product.metafields.reviews.rating.value contains real review data from a reviews app or metafield source.
