in the prestige theme find product-grid-item.liquid in the “section” folder if you don’t see then check in the “template” folder.
Topic summary
Main issue: Google Search Console reports large numbers of “Alternate page with proper canonical tag” for Shopify stores, often tens of thousands of URLs. Examples include collection-based product URLs (/collections/…/products/…) and product URLs with tracking/recommendation parameters (e.g., pr_prod_strat, pr_rec_id) or variant parameters.
Likely causes identified:
- Theme links generating collection-scoped product URLs via product.url | within: collection, creating duplicate paths to the same product.
- URL parameters appended by product recommendation features (“you may also like”), confirmed by Shopify support as passing recommendation context.
Proposed fixes and guidance:
- Add a global rel=canonical in theme.liquid so every template points to the clean product URL, avoiding per-page edits.
- Edit theme/snippets to remove “| within: collection” and link only to product.url to stop creating collection-based duplicates. Reported as an effective, scalable fix across themes (locations vary by theme).
- Optional: use robots noindex for non-primary duplicates, though the main emphasis is on canonicalization and link hygiene.
Status and open questions:
- Some users still see high counts after changes, likely pending Google recrawl/reprocessing.
- Theme-specific file locations (e.g., Dawn/Prestige) vary, causing implementation questions.
- No final universal resolution; thread remains active with requests for examples and further help.
