Do links hold there value after 12 months?

[Entrusteddev]

Hello, We need to find out if links that we setup, which are older than 12 months hold any value? Do new links hold more value than old ones and therefore should we let the old links become inactive? If we do let the links become inactive after 12month will that effect the PA/DA of the site?

"Aged" links are great in terms of seo. That is a quality signal that Google will use especially if you have a link from a high authority site.
