SEO · Updated June 2026
Duplicate content is substantially identical content reachable at multiple URLs. It splits ranking signals and wastes crawl budget. Common Shopify sources: product URLs inside collection paths, tag pages, and manufacturer descriptions reused across stores.
A canonical URL is the "official" version of a page declared via the rel=canonical tag, telling search engines which URL to index when duplicates exist. Shopify auto-canonicalizes product URLs within collections to the clean /products/ URL.
Technical SEO ensures search engines can crawl, render, and index a site efficiently: site speed, mobile rendering, XML sitemaps, robots.txt, canonical tags, structured data, and clean URL architecture.
