I just used auto translation but it appeared to be so incredibly bad that we cannot publish it.
I was using Weglot app before, and the auto translations were so much better! I wanted to switch to LangShop, because you offer fully customizable subfolder URL endings (highly relevant for SEO), which Weglot cannot offer.
So if you want to make your customers stick, you will need to work on the auto translation quality.
Maybe you can use an AI service like DeepL for your auto translations?
