Duplicate content, canonical and SEO

Noticed that Eshop not using canonical url.
As you can see....if product is in two categories. Say
top category1 and subcategory2
url for product can be
/category1/product
/category1/subcategory2/product

For SEO, this is not ok.

Hello Matj,

EShop does not use canoncial url because we have Main category for each product. So with each product we only have one link based on main category.

Sincerely, Giang

Please read my post again. One product with multiple categories have multiple urls. So same content with diferent url.

I have product with main category cat1. And sub category subcat1, cat2 subcat2.

Product have urls
domain.com/shop/cat1/subcat1/product
domain.com/shop/cat2/subcat2/product
domain.com/shop/cat1/product

Depends on where is shown.

when a product has additional category, This product will have two different addresses.
domain.com/shop/cat1/product
domain.com/shop/cat2/product
For SEO, this is not ok.
thank's

Hello

What's version of EShop that you are using? From newer version, we have Main category of product and the URL of a product will be based on Main category.

Sincerely, Giang

hello
EShop version 3.0.2.
I will check the latest version. thank you.

OK!

If it does not work like that, please submit a new ticket to EShop category so i can help you to check.

Well i guess this still is an issue.

My client has 101 products and the sitemap shows 391 URL's So definitly dupplicate content.

How do i fix this? Is there any option? Or should i use a plug-in to add the rel="canonical" tag ?

Perhaps a good solution is to disable "Add category path" Now all products appear only once in the sitemap. While browsing thorugh the site just works.

Is this how to fix the duplicates? Or is there a better solution?

Update: no it's not for my website.
