Here is a scenario:

1. website A links to website B.

2. website B does not link to website A.

3. the "href" link website A uses to link to website B is disallowed via website B's robots.txt.


Question:
1. From an SEO perspective, what happens when website A adds a "nofollow" to it's href outbound link to website B, given that the URL in the link from website A to website B is disallowed via robots.txt at website B?

2. Would adding a nofollow to a disallowed URL help and/or hurt either site and in what ways?


Thanks in advance and please feel free to share, I'd really like to hear everyone's opinion!:)

for me.. it doesnt hurt your site..

Google wont read the page if it's only link is from website A no need to place nofollow it'll just add to your code bloat.

Matts anwsers on robot.txt and others (http://http://www.stonetemple.com/articles/interview-matt-cutts.shtml)

Google has publicly confirmed that links with nofollow have no value whatsoever...

but it is still followed by other SEs like Yahoo...

Thanks to those who posted!:)

As it turns out Eric Enge asked Matt Cutts almost the same question during an interview two weeks ago. (Thanks for the link Jazajay!)
