As a WooCommerce store owner, you don’t want prospective customers to land on a blank, empty web page that shows no signs of content being rendered on it. This causes a poor user experience that can lead to visitors bouncing off your website.
Since images are the largest, resource-heavy elements on your web pages, optimizing them is a great way to reduce page load times on your site. This is particularly important for eCommerce sites that have lots of images on the main page, shop page, and category pages.
