We can write lots of content on main pages, product category pages but we do not have control over product pages which get content through xml feeds etc. Moreover they are availabe in the same form to lots of other affiliates also. We focus on product category pages and never intend to get traffic to individual product. So what should be the most appropriate thing to do. I have checked google mostly ignores these pages for most affiliate sites. So why not put these pages in noindex,nofollow ? Because that will also help when we decide to switch from present provider to another. Will it anyway be harmful to any site which puts thousands of its pages in noindex? And what if it has already few of them indexed in google and now we decide to put them in noindex? This is really important for me. Thanks a lot for your help.
