Different Permalinks for blog articles

Hi,

I'd like to have my blog posts under the /blog directory.

Something like your current hierarchy: giorgiobarilla.com/blog/article-name. Right now, it's giorbiobarilla.com/article-name.

I already know how to set up the 301 redirects in the https access (my articles have already been shared on the web, so I need to add those), but I don't know how to change the permalinks for the blog posts only.

I have other types of hierarchy. For example, my services are under:

giorgiobarilla.com/services/page-of-the-service, and I need it to stay like that, and portfolio will likely be on giorgiobarilla.com/portfolio/work-title

may you help please? I think this will serve a better organization for the SEO structure.
