Pr as it pertains to robots.txt

a Google Pr passing question

[mikemcs]

Does a disallow stop PR from going to a page. I have a few fluff pages that I want to stop PR from going to (Directions, Login, ...) is robots.txt the best way to do this?

No.

I wondered something similar. All my outgoing links pass through a php redirect script (visit.php) - the links are like mydomain.com/visit.php?sitelinkedto - and attempting to open visit.php throws up a 404 error as it's just a script. I have a suspicion I'm passing PR to a black hole. Would I be better making the script into a page that actually opens and displays a link back to my homepage?

What is the best way to stop the PR from going to these pages?

If you put this in an external js file:

document.open()
document.write('<a href="url">Linktext</a>.');

then name it "link.js" and use this as the link:

<script src="link.js" type="text/javascript"></script>

I believe this is effective but relies on having visitors who don't have js disabled.
