301 Redirect Domains with old links

[seoninja20]

I came across a nice discovery of about 20 old domain names that each have many root domains and a bit of DA. I want to know the best way to utilize them without any type of penalty.

Currently, (as of an hour ago) I am 301 redirecting all of them to the most relative pages on a single domain.

Will i get the majority of the link juice from the domains? I'm excited to see what will happen here.

Thanks in advance,

Daniel

It truly depends on what was done with the domain previous to them coming for purchase, or before you "found" them.  There is also the potential that someone purposely built up the rank only to abuse it, and the rank has not dropped yet.

If the PR's are legitimate and rather high, I might consider turning them into effective blogs on the subject they are dealing with and trying to maintain or improve it.  I also might see if I have clients that might need the domain for their business.

I do know that Google pays attention to this stuff, so if utilized poorly it could have a negative outcome due to "trickery."

Yes

Your actions are perfect. You are redirecting them to relative pages on your site. As long as the pages are truly relevant, then you should be in great shape. The basic test is, will a visitor be happy they found the page you are directing them to? Or will they have more of a "what the heck is this" reaction?

If you have re-directed the pages well, you will retain 90%+ of the link juice. How long that juice will last is dependent on several factors, some of which dignan shared.
