A few years ago I started a website with WP installed in a subdirectory (let’s call it ‘/folder’) to keep the root clean. Now I want to apply the following tutorial: Giving WordPress Its Own Directory – Using a pre-existing subdirectory install. It’s easy to apply but I don’t want to lose my Google ranking. So how can I redirect the URLs with ‘/folder’ automatically to the root?
For example: mydomain.com/folder/post-1 should redirect to the new URL mydomain.com/post-1, mydomain.com/folder/post-2 should redirect to the new URL mydomain.com/post-2 et cetera.
I guess I can fix it in the .htaccess file with 301 redirects, but after some research I still haven’t found a working solution.
