When does it make sense to use no-follow on your own domain?

[reegs]

Hey guys,

I'm not too sure if I'm over-thinking this, but I've seen no-follow being used with SEOmoz and I'm looking to implement this  myself.  Most of my links point to my root domain (yes I'm working on building links to deep pages) so would it make sense to 'limit' or 'no-follow' links on my root domain so that only the most important pages are being passed link juice?

Thanks

Hi Ryan,

not really.

This should explain - http://www.seomoz.org/blog/link-consolidation-the-new-pagerank-sculpting

Basically even if you nofollow the link you still pass the juice through it, except it just evaporates

So you'll be better off working on navigation structure and consolidation than trying to nofollow to pass PR.

However, in terms of when to nofollow, use it as intended! Pages that you don't want indexed or crawled you can still nofollow login pages, user comments and pagination etc.

links that SEs can't follow anyway like user logins are a great example of the proper use of no-follow. They can't log in anyway, so why deplete link juice to those pages?

Never for seo
but it is good to use on blog comments or where you dont want to rick linking to a spam site.
but for SEO, no-follows still lose link juice.

even for a login page i would still no use it, as linking to a login page that links back to your home page can be usefull in link sculpting
