Link Masking
 

I'm just wondering if someone can give me a bit of advice on the link mask generator of SEO Ultimate.

When I look for information on the Internet regarding this, I find:

Link Mask Generator

Lets you generate robots.txt-blocked "link masks" (e.g. http://www.example.com/go/google/) that pass-through to an external URL.
Lets you mask links on a per-link, per-post basis so you can exert fine-tuned control over your posts' linkflow.
Lets you change /go/ to a directory of your choosing.
Link masks provide a modern replacement for the deprecated, nofollow-based "PageRank Sculpting" technique.
Perfect for affiliate marketers and SEO-savvy bloggers.

However, that kind of leaves me with a few questions yet in mind: If I can change /go/ to a directory of my choosing, what directory should I choose? If Google is already crawling my website, do I just send googlebot to a directory they are already crawling? Do I set up a directory like /nocrawl/ and put nothing in it? These might seem to be "stupid" questions to many who are really internet savvy, but I would certainly appreciate a little advice on this question.

Thanks in advance,:)

I found a good article on it. Should answer my question.
