Hi Dirk,
Thank you for your reply.
Our problem is that all our our second levels used to be individual websites with DA and PA of around 25-30. Now however after the migration, what used to be the home pages of individual sites are now 1 level down from the domain and have lost a huge amount of authority.
Is there something we've done wrong or is this simply what happens when merging lots of sites into one? What was the home page with high DA and PA is now much lower due to being a subfolder.
Thanks!
