Welcome to the Q&A Forum

Hello We have a large ecommerce site, as you are aware that ecommerce sites has canonical issues, I have read various sources on how best to practice canonical on ecommerce site but I am not sure yet.. My concert is pagination where I am on category product listing page.. the pagination will have all different product not same however the meta data will be same so should I make let's say page 2 or 3 to main category page or keep them as is to index those pages? Another issue is using filters, where I am on any page and I filter by price or manufacturer basically the page will be same so here It seems issue of duplicate content, so should I canonical to category page only for those result types? So basically If I let google crawl my pagination content and I only canonical those coming with filter search result that would be best practice? and would google webmaster parameter handling case would be helpful in this scenario ? Please feel free to ask in case you have any queries regards
