I've got a site where people can list machinery for sale. Each item for sale has it's own dynamic page. On each of these pages we allow the person selling the item to have a link back to their own website. Some people only sell a handful of items and some people are selling dozens or hundreds of items. So in some cases we can have a 100 links back to their external site.
Our SEO guy is saying this is bad (i'll open another question on that). So i was wondering if i take the links and spit them out using document.write, will that hide them from google and the other SE's ?
