I added folders to some of my pages and the old pages still exist and are coming up in Google Webmaster tools as duplicate content and Meta. I can't see the pages in my webflow portal and I really just moved them over to a new folder and worked on them since.
As you can see the pages are pretty much the same.. But the one with the folder has an additional / to the URL as well are more complete.
The only alternative I can think of to not have duplicate Meta in Google Webmaster Tools is to simply update the meta and title tags for the folder pages. Which Ideally I would rather not do. I would like to simply delete the old Non Folder URLS.
