Canonical and Rel=next/prev Implementation

[GrappleAgency]

Hi,

I have an ecommerce site that allows users to view numerous pages and sort by a number of options on categories. I've read numerous posts around my issue but am still a little confused on what is best practice with regards to the canonical tag and rel=next and prev. Below is an example of the various page/sort by URL's:

Paginated URL: http://www.example.co.uk/category/subcategory.html?p=3

Sort by URL: http://www.example.co.uk/category/subcategory.html?dir=desc&order=price

Paginated & Sort by URL: http://www.example.co.uk/category/subcategory.html?dir=desc&order=price&p=3

It is not viable for us to use a canonical tag to the view all page as some of the categories contain a large number of products and therefore would not have the best load speeds. Is it best to use the below structure when it comes to the canonical tag and rel=next and prev?

Paginated URL: http://www.example.co.uk/category/subcategory.html?p=3

Sort by URL: http://www.example.co.uk/category/subcategory.html?dir=desc&order=price

Paginated & Sort by URL: http://www.example.co.uk/category/subcategory.html?dir=desc&order=price&p=3

http://www.example.co.uk/category/subcategory.html?dir=desc&order=price&p=2" />

Thanks

Looks like you got it right according to Google (as seen towards the end of this page) : http://googlewebmastercentral.blogspot.com.au/2011/09/pagination-with-relnext-and-relprev.html

Looks good to me as well, just as a tip. Don't forget to submit the parameters you're using in Google Webmaster Tools. In the menu item: URL Parameters are you able to configure if content changes with a certain parameter. It helps Google to understand your URL structure better.
