OpenCart Duplicate Page Remover

Duplicate Page Remover is a XML extension created by CartLabs, which overrides the OpenCart’s core linking structure and always creates link to only the canonical version of the product page from all listing modules, without compromising the core design and flexibility of multiple location listing capabilities.

Opencart’s core structure generates many duplicate copies of product pages through dynamic listing of products through category, manufacturer, tag, sort, list and pagination options. Read article How many duplicate product pages your store generates to understand the problem.

How Many Duplicate Pages Your Store Has? 

Let us do a simple math of how many duplicate pages will be generated for a single product mapped to just one category.

Static Listing Module (A) = 2 (Category, Manufacturer)
Dynamic Listing Module Sort (B) = 8 (Name, Price, Model, Rating) (Ascending/Descending)
Dynamic Listing Module Limit (C) = 4 ( Show 25, Show 50 , Show 75, Show 100)
Total No of Duplicate Product Pages (A x B x C) = 2 x 8 x 4 = 64

If your store has 1000 products, Google need to crawl 64000 pages unnecessarily. You need to eliminate the creation of such dynamically generated ghost versions of product pages. Our XML coded extension just do this for you.

What Duplicate Page Remover Does?

DPR changes the linking structure and links from all over the store will point to original Product Page. Crawlers will be able to access just one copy of the product page.

Before DPR URLs look like below

http://store.com/product (Original & Canonical Version)
http://store.com/category/product
http://store.com/category/subcategory/product
http://store.com/manufacturer/product
http://store.com/tag/product
http://store.com/category/product?sort=pd.name&order=ASC
http://store.com/category/product?sort=pd.name&order=ASC&limit=25
http://store.com/category/product?page=2
http://store.com/category/product?sort=p.price&order=ASC&limit=25&page=2
http://store.com/category/subcategory/product?sort=p.price&order=ASC&limit=25&page=2
http://store.com/manufacturer/product?sort=p.price&order=ASC&limit=25&page=2

After DPR activated links from all pages to just one URL

http://store.com/product (Original & Canonical Version)

How Duplicate Page Remover Works?

Duplicate Page Remover overrides the OpenCart’s core linking structure and eliminate the dynamic product page url creation from all listing modules. Links from all over the site will lead to one unique product page (http://store.com/product) which is the canonical and original version. As a result search crawlers get to know only one page for each product. This effect would greatly increase your site climbing up in organic search results as there are no more duplication of contents.
