hide affiliate links from googlebot? / SEO implications

load affiliate links in iframe?

[mcglynn]

I've been building a content site for about 18 months and am finally ready to put some affiliate product links into the pages.

Am I risking the authority and trust I've built with Google (by having a purely noncommercial, authoritative informational site) by putting, say, Amazon product links onto the pages?

Should I nofollow the affiliate links? Or should I load them via an iframe or via javascript so googlebot doesn't even see them?

a) no follow doesn't work anymore regarding containing rank - it only makes oyu not vouch for the linked site
b) I think it (g-bot) can read JS
Maybe channeling the links through a kind of redirect script helps - I am tinkering with this issue myself

I know about nofollow and the sad demise of "pagerank sculpting." I'm trying to figure out if it's sufficient to use nofollow just to block what are essentially paid links (of a sort) from passing juice... or if I should use an iframe so that the commercial links don't even appear on the content page.

The next option is to block the iframed content via robots.txt, so that search-engine spiders don't index the affiliate links at all.

It's all possible, but is it important?
