If you can get the link to stay more than 6 months to a year on a page very relevant to your site's topic, it will add to your site's semantic link to that subject.
That is, to Google's brain, it's very very probable that your site is related to whatever that page is about because the link's been there for a long time and it's probably getting clicked..
It does not pass link juice, it only serves as a strong indicator that your site is about that subject. But only if it stays there 6 months to a year or more ideally.
