Good to know
Translation apps translate products, theme and often texts from other apps, mostly by machine with manual correction. For search engines, each language needs its own URLs with hreflang. Most translation apps do not need customer data.
Isn't Shopify Translate & Adapt enough?
Shopify's free app translates part of the content and suits simple stores. Apps like Weglot or langify often translate more, such as texts from third-party apps, and offer glossaries or an in-store editor.
Are machine translations good enough?
For product descriptions mostly as a draft, not unchecked for legal texts such as terms or the withdrawal notice. Plan time for corrections.
