User-experience improvement is a primary contribution of AJAX to the store's overall success. Use of AJAX techniques results in decreasing page loading time and bandwidth usage. Thus, there are two evident advantages: customers don't wait long for a page to refresh and traffic is considerably reduced.

Due to the use of powerful client-side data retrieval techniques, AJAX selectively modifies a part of the page displayed by the browser, and updates it without reloading the whole page with all its images and menus. AJAX is extensively used in the CS-Cart customer area and administration panel,making your store more dynamic and user-friendly.
