Locale Proof

Finds the localised URLs your store advertises to Google that do not work — dead links, one-way hreflang, canonicals that cancel your own language versions.

Locale Proof is installed from the Shopify App Store. Open it from your store admin to get started.

It reads your published languages and then checks, from outside, what a search engine actually receives. It reports what it checked and states what it did not check. It does not judge translation quality.
