nofollow attribute to all external links

[free3yourmind]

Hello,

I am looking a way add the nofollow atribute in all the external links of a webpage. I would like to know if is there any code that i can add in my website and automatically make all extrernal links "rel=nofollow"

It's not about magic code, but using your cms / editor. Find and replace might do most.

Probably a suicidal gesture in SEO terms, however.

I imagine you could find and replace any absolute URL that isn't your domain, and add nofollow. Or do it on the fly. But...

This Nofollow thing is getting out of hand. What would happen if every site NFed every outbound link. Its stupid, and I suspect Google will start frowning on excessive use, if they don't already.

All the external links in my pages are affiliate links and this is the reason i want to add the "nofollow". My website is created with MSPublisher and i cannot add in each nofollow attribute, the only way to do it is to add a code fragment at the top of the page that will do it for all the external links. In another forum they sugest me this what y think?

<META NAME="ROBOTS" CONTENT="NOFOLLOW">

Using a nofollow robots meta tag is likely to stop search engine spiders following internal and external links - BAD IDEA.

Death of a website, nofollowing all internal links.

To emphasise; it WILL stop SEs spidering your internal links.

I think there is a technique which works something like this (I don't do this, someone please elaborate or correct as appropriate)
All links to outbounds look like this
href="http://www.yoursite.com/refer?URL=http://www.affiliatesite.com"

PHP to redirect from the URL

Then robot.txt to disallow /refer

Although thinking about it, that won't keep PR on your site, it will just get lost to the redirecting URL.
