WooCommerce Infinite Scroll and Ajax Pagination

“WooCommerce Infinite Scroll and Ajax Pagination” is a WordPress(WooCommerce) plugin to convert default product pagination into Infinite Scroll or Ajax pagination.
When a user scrolls towards the bottom of the page, the next page of products are automatically retrieved and appended.
This means they never need to click “Next Page”.

You can also add “Load More” button instead of Infinite Scroll or you can keep default pagination as is and convert it into Ajax Pagination.
