A product isn't really translated if its meta title, description, URL handle or alt text is still in English. Civet checks every language, lists what's missing, and a preview run fills the gaps.
Shopify Markets puts your translations on real language URLs like /de/ and writes the hreflang tags itself. Civet doesn't inject anything, and the free readiness check confirms those tags are there and pointing at the right pages.
Will this get you to #1 on Google? We won't promise that, and you should side-eye anyone who does. We just make sure every market has all its pieces.
