Subpages have Page Authority of 1 behind Home with DA 50

[brainfruit]

How come that our subpages all have a PA 1 if the home got DA 50?

technical specialities:

• Megamenue opens on click only
• Category pages dont exist (home/i-do-not-exist-as-page-category/PA-1-subpage)
• All subpages have a high amount of links to ressources (over 200)

what would be the most obvious cause for the low PA? would the external link profile be the main reason?

thanks in advance. I would be happy to answer your questions

Kind regards

I have a couple questions. How long have these subpages and their backlinks been live? When you use the Moz tools, have your backlinks been indexed?

Hi,

no problem. I am happy to answer them:

the subpages are live since the launch.

the subpages have been crawled:

Linking root domains: 0

Status: 200

the main issue is duplicate content as the different language urls link to the same page:

home.com/gb/subpagenr1

home.com/de/subpagenr1
