Hi @14thday,
Thanks for your review. We’re sorry to hear you’re having difficulties using Yoast SEO in your language. Our plugin fully supports multiple languages, including Spanish, French, German, Portuguese, Italian, etc. You can see the list of supported languages in this article.
If you want to use Yoast SEO in your own language, we’d recommend you follow this guide. You should be able to add a non-English focus keyphrase in the Yoast meta box. If you still have problems, please create a new topic in the plugin forum. Our support team will look into the issue and assist you further.
As for your second comment, I believe you mean meta keywords tags which are useless for SEO as we discuss in this link. That’s why we removed them from the plugin several years ago.
