I work on an ecommerce website which contains products which differ by its size. We set this as configurable product with different SKUs at back end. But in Google webmaster gives duplicate Meta tag error for that product. How to fix it?
Firstly, there should not have any duplicate meta tag error in the Google Webmaster. Try to fix all that errors if you can. But in case of product page, you can add a canonical tag on that page. This will help you to fix this problem.
