We have an Ecommerce website and I have allowed 3 reviews per product page, then it moves to another page for 3 more reviews making duplicate url page for the same that looks like this
https:// www. xyz.com/xyz
https:// www. xyz.com/xyz?pagenumber=2
How can I stop this? I am sure I cannot put it into the robots.txt since this doesnt have forward slash(/) ?
