Ajax Pagination in Magento Question

[vetofunk]

Hi,

We just launched our new theme for Magento and my developer stated the pagination uses Ajax. Previously I had the developers set up rel prev/next for all our pages (categories/ecommerce site) that had multiples. He said it's not required with Ajax. Is this correct?

Example:

https://www.bestpricenutrition.com/whey.html

and when you go to Page 2, the URL shows:

https://www.bestpricenutrition.com/whey.html?

I want to make sure these pages are set up correctly.
