hi i run a eCommerce store .i have a large inventory of products most of the product description is same for all products and its mandatory to include it. its creating a large duplicate content on site . each category have 6 products i thought of a solution can you suggest which one is good 1 no index and follow product page and link it to categories page using canonical tag 2 index and no follow product page and link it to categories page using canonical tag which is the best solution and is it a good practice to use canonical tag to link to categories page or is there any other methods to avoid Google panda penalty
