Blocking page rank flow accross links?

[hugh]

What means are there of acheiving this aim without the use of rel="nofollow"? JavaScript used to be an option but no longer it seems. And what about redirection and robots.txt?

[tedster]

You can use javascript redirection via an external script - if the script's location is blocked by robots.txt. Here's a recent video from Matt Cutts [youtube.com] about this. Note that you can also embed nofollow within the javascript link.

Redirection (301) still flows PageRank. There may be some slight damping, but it's still being voted across to the target URL.

Thanks tedster, I'd read the article but hadn't watched the clip which answers my question...
