Link juice on sub domains

[roberthseo]

We have got all our clients linking to our website blackpen.tv

Based on a user's location they will be redirected to a sub domain.

So for example someone in France clicking on a link blackpen.tv would be redirected to paris.blackpen.tv or blackpen.tv/paris

Would this affect the amount of link juice passed down?

If the link is not the destination URL the user lands on (in some cases), then yes, it's not the optimal situation for the maximum amount of authority being passed. But that's also dependent upon how the user is being redirected...

Hi, it sounds that you are really trying to rank your sub domains as well.To add to Brady's question, a lot of that depends on how and where the user is being redirected and how you are building out your sub domains. If you are going to use sub domains you need to make sure everything is optimized on and off the page. If you do this consistently and your redirects are correct, you will pass some link juice and your sub domains will start to rank.

Usually the redirects Roberthseo describes are 302.

For instance, I am redirected with the 302 to http://blackpen.tv/language/en/, because I am in Spain when accessing to blackpen.tv.

That means that if somebody from Paris is linking to blackpen.tv and not to the paris.blackpen.tv subdomain, no link equity is passed because of the 302, even though it is also true that Google (aka: Matt Cutts) told once that in some special occasions (i.e.: when it is clear that a 302 stands for a 301), we can 302 treated as 301 (but, sincerely I don't think this is the case).

So, the best is always to have backlinks pointing to the exact location.
