There are several situations where a store owner may realize the need to develop an eCommerce Progressive Web App (PWA) for their webstore. This includes when they are new to the e-commerce business or have just launched their online store, if they notice a decline in the conversion rate on their website, or if they want to create a native app but are limited by budget constraints. Additionally, developing a PWA can enhance the browsing experience for mobile users, especially since mobile traffic is often higher.
