How to fix seo facet url not canonicalized on PrestaShop
Add a canonical tag to every filtered, sorted, and paginated collection/category URL pointing back to the clean (unfiltered) category URL, so Google consolidates duplicate pages and focuses crawl budget on your real content.
Steps for PrestaShop
- PrestaShop generates canonical tags via its core SEO module. Go to Shop Parameters → SEO & URLs and enable 'Canonical URL' if available in your version.
- For faceted search (the native Faceted Search module or ps_facetedsearch): go to Modules → Module Manager → Faceted Search → Configure. Look for a 'Generate canonical URL' or 'SEO' option and enable it — this sets the canonical of filtered pages to the clean category URL.
- If the module does not provide this option, edit the ps_facetedsearch module template or override the canonical tag in your theme's header.tpl to output the base category URL for all layered navigation pages.
- Clear cache: Advanced Parameters → Performance → Clear cache. Verify with Google Search Console.
What is seo facet url not canonicalized?
When shoppers filter your product listings by size, colour, price, or sort order — or browse to page 2, 3, etc. — your store generates a new URL for each combination (e.g. `/collections/hoops?color=red&sort=price` or `/collections/hoops?page=5`). These "facet URLs" display largely the same products as the base category page, making them near-duplicate pages. A canonical tag is a small piece of HTML that tells Google: "Treat THIS page as the authoritative, indexable version — not the one you just crawled." Pointing every facet URL's canonical back to the clean category URL (e.g. `/collections/hoops`) is the standard, Google-recommended way to handle this.
Without canonical tags, Google may index hundreds or thousands of near-identical filter and pagination URLs instead of your core category pages — diluting the ranking signals (links, authority, clicks) that should be concentrated on those pages. Crawl budget is wasted on low-value filter combinations, meaning new or updated products get discovered more slowly. Duplicate content confusion can push the wrong URL into search results, giving shoppers a paginated or pre-filtered page that looks broken. Fixing canonicals consolidates ranking signals onto your clean category pages, improves crawl efficiency, and protects your organic traffic from unnecessary duplication penalties.
