When creating a multilingual website the first question you’ve got to ask yourself is: Does everything need to be translated.
My answer is not always.
Blog posts for example don’t always need to be translated into both languages. If the blog post is about English lessons for example we could assume that we don’t need to translate it into English as well.
However nice it would be to have everything translated you’ll eventually find that it can be quite time consuming. Writing a blog post can already take quite an amount of time. If you want to translate it correctly then this ends up taking even more time and we all know that time is precious.
