I have submitted sitemap to google and it keeps identifying unique product pages as duplicates. Can someone please explain why its happening and how to resolve them please.
All the product pages are generated dynamically. below is a sample example
Original URL: https://www.example.com/ProductDetails/barcode/9780008294816
Google-selected canonical: https://www.example.com/ProductDetails/barcode/9780008276324
The last part represents the ISBN of the books. Both are different titles but google thinks they are same.
