Hi, Can I put "no follow" tags to CJ's affiliate link? Do you put affiliate links as no follow or do follow? Please provide your reasons. Thanks Thanks.
Won't really do any good if you're trying to manage your page rank. Google will still see the link and take it into account for the flow of your links on your site. It just won't apply the weight onto that link. Reference: http://www.mattcutts.com/blog/pagerank-sculpting/
You can, and it definitely wouldn't hurt, but if you're mostly doing PPC, its not going to help either.
Yep! You can and you should as one other poster has already mentioned. The other alternative you have if you want to screen out Google from following your links into your merchants is to send your links through a redirect (another page on your site with a server-side link to your merchant) but then use the robots.txt file to block access to that redirect file from spiders. This way it's left squarely in the domain of your users...
