When a product title or description changes in the source language, it is easy for the translated storefront to fall out of sync. I use this small review loop to catch the common problems before they become customer-facing. Keep a source snapshot Before a catalog update, export the relevant product content or save a dated copy. A row number is not a reliable identifier: exports can be sorted differently next time. Compare by key, not by position After the update, compare the old and new source values using the stable key plus the field name.
