Welcome to the Q&A Forum

Hi, I'm setting up a blog for a client that has a .com domain. The client is targeting three languages with the subfolder /de, /nl and /en. We've also established that a blog rather be used in a subfolder than subdomain. My question: How should we implement the three languages? Is this gonna be a domain.com/blog/en or domain.com/en/blog or would you maybe don't use subfolders for language at all but let a hreflang do the job?
