The Pagination Controls is the format from Magento 2 for the product listing. You can set the number of links that appear in the control, and configure the Next and Previous links. To appear the pagination link, it is required when the number of products that need to be shown is greater than the permitted amount in the product list settings.
After setting the pagination control, your customers can get the control at the top and bottom of the product list. Thus, Configuring the Pagination Controls is one of the smart ways to make the performance of your site more professional.
