language code prefix

Hi there,

I’m wondering if there is any way to integrate a language code prefix instead of that “?lang=en”..

My question is related to the SEO rules and I guess that if the web could manage the different languages with like folders (/es /en /fr) it could help us to rank better..

Any suggestion for that?

Thank you in advanced ??
