Page authority is extremely underrated. Even if you have a low domain authority, if you have a high page authority, you can rank above places like Wikipedia or others.

Moz treats all the links as no-follow so they don't actually help with indexing but as a random example if you had a root domain eg: https://www.poof.io

and you had a subdirectory: https://www.poof.io/payment-gateway/ethereum

Page visibility would be higher on the subdirectory if it were shared a ton of times with non-nofollow. If it didn't have high page authority and were just a page, then it would be indexed by Google but likely not very high up.
