I just started an e-Commerce site and as I am aware of thin page/duplicate page are bad for site. I no-indexing all my product pages which contains only size and colours data for the product ( no unique product description)
I am focusing/expecting/trying to rank well on category pages ( enough unique written contents describing that category ) and article pages.
So now my site will have like 80% of pages as no-index. So by this I am getting rid of bad effect of thin page/duplicate page.
But is it bad for ranking for having this too many no-index ?
