Can you regain any SERPs / link juice of links that have 404'd?

[SavvyPanda]

We have a client whose 301 redirects disappeared and have been gone for about 6 months now. We are going to be putting the 301 redirects back in place.

Will we be able to regain any of the previous SERPs or link juice from old links or is all lost?

Thanks in advance!

In my experience, yes, you can regain value.

I redirected an old microsite with external links (which had been abandoned a few years prior) to the relevant page on my current, active site and that page quickly grew to become one of the strongest pages.

[There had been a thread on this here in Moz if you want to read more.]

Awesome thank you for sharing your experience that's a great data point.
