Internal site navigation should always link to the required page and not to a URL which then redirects.
Asking for old URLs should redirect in ONE step to the new URL and not through a chain of redirects.
These are signals of "low technical quality".
There's no trust in internal links that redirect. PageRank doesn't pass through multiple steps.
