Progressive web apps or PWAs are becoming mainstream with each passing day. PWAs offer native app experience through a browser without the need for any installation. In simple words, PWAs can be considered the combination of mobile apps and websites and offer the best of both worlds. You can just add a PWA to your home screen and use it as an app.

Benefits of Progressive Web Apps (PWA) for Business

Progressive web applications have some distinct features which vary with native apps and help them offer optimum web experience. Some of the essential features of PWAs include-

Web App Manifest: The web manifest is a regular JSON file that contains the WPA’s metadata. The developer can use the manifest to control the appearance and launching of the PWA. 

Employs HTTPs: Secure by Default: WPAs exchange information and data over a secure HTTPs connection to prevent any unauthorized intrusion. 

Registered Service Worker with Fetch Event Handler: Service worker enables PWAs to provide capabilities like push notifications, background syncing, offline working and more. It is essentially a JavaScript file that responds to user interactions. 

Works Offline: PWAs utilize caching to load instantly on repeat visits. Some content resides in the device while the dynamic content is refreshed on each visit. PWAs can provide the basic functionality without the need of internet. 

Fast by Design: It takes far less time to develop PWAs compared to native apps. You don’t need to know any special language and can rely on your HTML, CSS and JavaScript knowledge to develop a PWA. 

Integrated with Platform: You will never need to worry about platforms in the case of PWAs. They will work on all devices and platforms as they are made with responsive web principles. iOS is also on the way to provide support for PWAs in a short time.

PWA Minimal Requirements

PWA Minimal Requirements

You need to fulfill three technical requirements to get started on PWA-

HTTPs: Most modern sites have already shifted to HTTPs for security. You will also find most of them using TLS or SSL for encrypting the data for safety. PWAs need HTTPs to be compatible with current APIs like service workers.

Web manifest: Web manifest is a regular JSON file used by the browser in the background. The metadata in the file is used by the platform and browser to add the PWA to your homescreen. You can also use it to define your launching URL, icons, color schemes and more. 

Service worker with offline caching: You will need a registered service worker with a fetch event handler to enable browsers to initiate the add to home screen workflow. The feature is required to determine if the PWA will be able to work offline. 

PWA User Experience Requirements

PWA User Experience Requirements

Now that you have ensured the three technical requirements, the next step is to provide a stellar user experience. Your PWA should be-

Fast: A web page takes 19 seconds to load on a mobile on average. If your PWA loads slower than that, it can hamper the user experience. 

Integrated: Your users should be able to use your PWA, just like any other native app. It should offer an integrated experience, with everything doable from the app itself. For instance, you can use Web Payment APIs to allow users to checkout without tackling traditional checkout workflows. 

Reliable: Service worker cache enables PWAs to load in a flash and offer offline capabilities. You will be able to create a functional user experience even when there is no internet through offline caching workflow. The size of your content may bring up some caching limitations, but still, you will be able to create a serviceable offline experience. 

Engaging: PWAs allow you to create high engagement using background updates, push notifications and more. For instance, you can use push in your PWA to alert users about new deals or promotions.

Discoverability of PWAs

Native apps are hard to find! You need to go to the app store and search specifically for your app. Then also, there’s no guarantee you will find the app as App stores often suffer from poor indexing. For all of these reasons, it’s difficult to market native apps, and the process is costly too! It takes around $8 – $30 just to acquire a single app install. 

Progressive web apps can be found through search engines and offer an excellent opportunity for marketing as 93% online activity stems from a search engine. You can optimize your PWA landing page for search engines, take the help of PPC and more to increase the visibility of your PWA. 

You can also do all of your marketing at much lower costs than promoting a native app. Organic traffic comes for free and you can use simple tweaks to increase discoverability of your PWA. Native apps don’t provide such advantages.

PWAs are the future and will give a tough competition to native apps for their ease of development and deployment.
