301 redirect & backlinks

Hey guys,
If I forward domain A via 301 redirect to my target url B, but later redirect A to C instead, will anchor and linkjuice pass to C? If so, how fast the "credits" will transfer and effect SERP & PR?

 

301 redirect will pass the link juice, but not all the time (most will pass though).

You should also be careful using 301 redirect too much. Google will see this.

 

if your redirect url for 301 redirect than u will get good Page Rank for your website with out optimize

 

Yes, if you do 301 redirect from A to C later, it will still pass link juice and Anchor

 

thank you, guys.
what about URL shorteners? do they pass juice or not? (I posted a separate thread on it too).

 

To have your question answered by a professional, here are two related videos by Matt Cutts. Do take a look :
Does anchor text carry through 301 redirects?
Are shortened URLs treated differently than other redirects?

 

The links with 301 redirects will also pass link juices. Of course, in the whole process, you will lose some obviously.

 

so, accordingly to the video shorteners as well pass juice... ok, good... tx, guys.
