General Question: Linking Root Domains 0

[brainfruit]

Hi,

we have several subpages with PA 1. We try to figure out why.

The link metrics show 0 Linking root domains, but shouldnt there be at least the own domain like 1 linking root domain or are we getting it already wrong here?

The subpages have following link metrics: 0 External followed Links. 8416 subdomain and 8421 Root Domain, Linking Root Domains 0, 299 Subdomain, 302 Root Domain (From Mozbar).

The pages seem to be crawled. We are suspecting techincal reasons.

What would be the impact of the linking root domain to the PA 1?

Thank you in advance
