Why is Link Explorer showing the same domain strength for domain and sub-domain? Shouldn't it be different?

I believe in the past the sub-domain score was different than the domain score in Link Explorer.  Now I am seeing that it is reporting the same score.  I have to use exact page to get a sense of how strong the sub-domain is.

Hi - Thanks for posting!

Domain Authority scores are representative of the entire root domain. Sub-domains do not have a separate Domain Authority from their root domain.

Link Explorer will always show the same Domain Authority score for any URL searched on a root domain, regardless if searching by domain, subdomain, or exact page in the tools.

You can read more on Domain Authority here: https://moz.com/learn/seo/domain-authority

We hope that helps to clarify!

Thanks for the quick response.  If that is the case why is there a sub-domain option?  Is it only to have the ability to see linking domains and links?  Not to have the ability to see authority?  I then typically default to page authority to have a sense of the authority of the sub-domain.
