A technical but practical guide to localizing your URLs and slugs — building a clean per-market URL structure, setting up redirects, and avoiding the SEO damage of a botched migration.
A localized slug like example.com/fr/robe-ete tells search engines and shoppers that the page belongs to their language — and it earns clicks a foreign slug won't.
Your URL pattern — subdirectory, subdomain, or Markets — determines how the whole storefront scales. Changing it later means a painful migration with redirect risk.
Translating slugs without mapping old URLs to new ones breaks inbound links and drops rankings — the SEO damage is real and often invisible until too late.
