We currently have around 5-10 colour/size variations per product on a configurable page and were thinking of changing to Simple Sku so that we have more product pages and will rank for each colour variation other than just the generic product. However with configurable products we could enable product reviews which would mean that we get more reviews on one URL as opposed to a less reviews on multiple URLs for color variants. Also, we are thinking that we will get more links and traffic to one page rather than multiple pages of the same product as well as time spent on that particular page. What is the consensus on what is better for SEO on this? Many Thanks
