Pager Optimization for Magento Stores

If your ecommerce site has paginated content - avoid duplicate issues between product pages in several ways.

1. Rel=“canonical” to the view-all page.
If your store offers a few products of the category, it's more preferable to show the whole category on a single page. Yet this function is disabled in Magento by default, so you can enable it in System -> Configuration -> Catalog -> Frontend -> “Allow All Products per Page”.

Add rel=”canonical” link to the component pages to tell Google that the View All page is the one you want to appear in search results.

2. Pagination with rel=“next” and rel=“prev” (+ rel= “canonical”)
In case you sell a large number of products of the category, add rel=”next” to page one, then rel=”prev” and rel=”next” to page two all the way to the last page which only includes rel=”prev”.
