Is there any SEO benefit for "do not follow" on a large number of sku's on my site.
These products are add on's for sales of my main product category. There are thousands of them and they are sold by scores of other companies like amazon, sears, etc. I will rarely rank in the top 40 searches for any of these products. Most people find them on my site while buying my main product.
So, is any of my PR/"link juice" being marginalized by having these items indexed by google?
Thanks for your help
