What is a Progressive Web Application (PWA)?
A PWA is essentially a website that functions and feels like a traditional app. It has the ability to be “installed” on a device and can load instantly, regardless of whether the user is online or offline. PWAs enable a smooth user experience, mimicking that of a native mobile app.
Why use a Progressive Web Application (PWA)?
Companies use PWAs to align with mobile-first strategies, enhancing their online presence and enabling a smooth user experience on any device. PWAs avoid the need for different versions of apps for multiple platforms. They can also function offline and send push notifications, beneficial for user engagement. PWAs are accessible via URLs and are indexable by search engines, enhancing the company’s SEO.
When to use a Progressive Web Application (PWA)?
PWAs are beneficial for businesses that want to enhance their mobile presence without investing in a standalone app. They’re particularly useful when the majority of a company’s target audience uses a browser to access its services. PWAs are great for businesses that need their apps to work in areas with poor internet connectivity, as they can cache parts of the app for offline use.
Where is a Progressive Web Application (PWA) used?
PWAs can be used in various industries including e-commerce, news sites, and social networking platforms. They can be run on any platform with a standards-compliant browser. Major brands like Twitter, Starbucks, and Pinterest are notable examples of the practical applications of PWAs.
