I am having an issue with one of the websites. Google is reporting that I am having duplicate meta descriptions for few pages. What we did is that we used url rewrite to rewrite the pages to be more seo friendly. Here is one example with one of our product pages:
Old format: www.mysite.com/Product.aspx?ProductID=12345&SKU=44412-2212A New format: www.mysite.com/Products/12345-44412-2212a.aspx
What we are doing now, when someone will ask for
www.mysite.com/Products/12345-44412-2212a.aspx they are taken to
www.mysite.com/Product.aspx?ProductID=12345&SKU=44412-2212A but the url still remains
But if someone type in
www.mysite.com/Product.aspx?ProductID=12345&SKU=44412-2212A, they will see exactly the same page as
www.mysite.com/Products/12345-44412-2212a.aspx since the data on the page is same.
What I was thinking is to block product.aspx pages in robots.txt file, but I don't know if that automatically will block google robots from crawling this page too
www.mysite.com/Products/12345-44412-2212a.aspx, since that one is only url rewritted page from the other page format,
What do you guys think, how can we tackle this problem, any advice, because GWT is reporting that I have duplicate meta description issue, and those are the pages reported as duplicate, I want to have only one page per product?
