[مغلق] Severe SEO Impact from "Browser Language Redirect" Feature

Contesto del problema:
I experienced a significant drop in my website's search engine ranking after enabling the 'Always redirect visitors based on browser language (redirect to homepage if translations are missing)' feature in WPML. This has led to a sharp decline in traffic, especially in my default language, Italian, which has negatively impacted my business financially.

Sintomi:
My website's ranking on search engines dropped significantly, resulting in less than half the visitors I used to have, causing a financial impact of over 50%.

Domande:
Is there anything I can do to recover from this damage, beyond disabling the feature?
Are there any recommended steps or best practices to help restore my site's SEO visibility in the default language?
How can I prevent this from happening again in the future?
