    Ever imagined a scenario where you don’t need to install an app from the play store for accessing an informational or shopping website? Progressive Web Apps help you achieve this by providing a seamless, app-like experience when you open a website on a mobile device.

    Progressive Web Apps (PWA)

    What are Progressive Web Apps?

    Progressive Web Apps, commonly known as PWAs, are a set of technologies that can be used to make a website look and feel like a mobile application. The way PWAs are able to achieve this is by using APIs (application program interface) that use a combination of both web and native app features.

    Websites that use PWAs function entirely like a mobile application that we install from the Play Store/App Store, thanks to their integration of service workers (used in native mobile apps).

    So you don’t really have to install a mobile app the next time you want to do some window shopping! A breath of fresh air for your mobile storage, isn’t it?

    What are the features of a PWA?

    Here are the features that make a progressive web app better than a traditional web app:

    • The web apps built using PWAs are blazing fast. Google wants websites to have an FCP(First Contentful Paint) lesser than 1s. So it would make sense to integrate PWA’s to achieve this.
    • Just coding your website in a way that it looks and feels like an app isn’t enough. Some of the features that PWA’s provide to make your website engaging are: 
    • PWA’s take advantage of something known as Service Workers, which is one of the core functionalities of a native mobile app. A special thing about Service Workers is that they use pre-caching which enables the web app to load seamlessly without any dependencies on the network. This makes your progressive web app reliable by loading even on slow internet connections and 2G networks.

    Why Progressive Web Apps (PWA)?

    The most amazing thing about PWAs is that they give you the best of both worlds—the browser and the app. There is no debate about the flexibility and robustness of mobile apps. But let’s be realistic, users can’t be expected to install an app for every website that they visit on the Internet. To convince a customer to go through the stages of downloading your app, installing it and then using it to make a purchase, there has to be an established relationship of trust between you and your customer.

    In the light of this, here’s an interesting statistic: at each of these various stages, a mobile app loses around 20% of its users.

    Mobile App Statistics

    Your best bet in such cases is to use a PWA. Users can engage with the PWA immediately without having to go through the additional steps of downloading and installing the app. 

    Characteristics of PWA

    • Responsive

    One of the most striking features of PWA is that they are responsive and can appear perfectly on any screen. A Web page created using PWA will automatically adapt to mobile phones, desktop, laptops, tablets or any other future devices.

    • Discoverable

    PWA have service worker registration scope and W3 manifests that makes it easier for search engines to locate them. This will ensure that your Web pages are easily discoverable.

    • Safe

    PWA also offer a lot of security. Thanks to the transport layer security (TLS) used by PWA, there is no chance of snooping and data tampering.

    • Fresh

    The update process for service workers ensures that PWA are always fresh and up-to-date.

    • Independent of connectivity

    PWA can load fast even when connectivity is poor. Service workers have certain features that allow PWA to load offline.

    • Installable

    Progressive Web pages can be installed on the home screen of mobile phones, giving them an edge over traditional Web pages.

    • Better engagement

    PWA support “push notifications” which lead to better engagement. Push notifications sent to users appear in the notification panel.

    Should I use PWA for my website?

    Yes, absolutely! The reason why progressive web apps are important is because they give users a seamless interface to interact with. This helps build trust among the users and the quick response time of PWA’s is the icing on the cake.

    Let’s talk in terms of our traditional marketing funnel:

    • Awareness 

    According to a report by Comscore, the reach of the mobile web is a whopping 2.5 times more than that of apps.

    Not everyone likes to install apps for every website that they visit. This is one of the sole reasons why the approach of going “app-only” and abandoning their mobile website didn’t go down too well for big companies like Flipkart and Myntra.

    Using PWA helps you ensure that you are reaching out to a large number of audiences that use mobile websites to surf. 

    Tinder, a location-based dating service, created a progressive web app TinderOnline which was 90% smaller in size than their mobile app and drove a huge number of audience interactions.

    • Consideration 

    Once you’ve reached your target audience, it is necessary to gain the trust of the user.

    By using Progressive Web Apps you can ensure that you’re providing your audience a mobile website page that is fast, reliable, and engaging. 

    The functionalities of PWAs like push notifications will help ensure that your user is engaged(kind of remarketing) and finally considers buying a product from your website.

    Trivago, a German company providing internet-related services and products in the hotel & lodging field, was able to increase engagement by 97% by using PWA.

    • Conversion

    When we talk about conversions, we talk purely in terms of numbers.

    The ability of PWA’s to use API’s from native apps make the whole transaction process seamless. The various gateway implementations prove to be a boon in transactions and help you in your conversion rate optimization.

    There are many success stories of companies that have significantly increased their revenues by adapting to a Progressive Web App approach.

    • Treebo

    • Uber

    A multinational company built m.uber, a progressive web app to help its users on low-end devices and slow 2G networks to quickly book a ride.

    • Nikkei

    One of the well-known media businesses in Japan, who had problems with their Page loading time which ultimately led to bad user experience and affected their revenue numbers as well.

    They put out a case-study showcasing how they were able to decrease their Page Load time using PWA’s. This ultimately led to an increase in revenue and build a consumer base.

    • Pinterest

    A famous social media company, re-built their mobile site in PWA which resulted in a 60% increase in their engagement rates.

    You can find many such case-studies that showcase the capabilities of Progressive Web Apps at PWA Stats.

    Google also has its very own section where various PWA case studies are posted.

    Get started with PWA

    In order to set up PWA, there are three important things that you need to have in place:

    • Service worker

    The most significant component of PWA is the service worker. It is a script which handles all the network requests in the background. It also processes all the complex instructions to serve PWA.

    • Manifest file

    A Manifest file contains all the information about how a PWA should appear and work. It is a Javascript Object Notation (JSON) file that defines the name, description, icons, colours, and other properties of a PWA.

    • HTTPS connection

    PWA do not compromise on security. If you decide to migrate your Web page to PWA, a secure HTTPS connection is required. PWA won’t function on an HTTP connection.

    In order to build your first Progressive Web Application, there are plenty of resources you can refer to. There are also many tools in the market which can help you to migrate your Web pages to PWA. Google has easy and in-depth documentation on PWA that you can find here.

    Challenges in Progressive Web Apps (PWA)

    • Browser Support

    While many browsers support progressive Web apps like Opera, Chrome, and so on, there are a few that don’t support PWA, such as Safari and Microsoft Edge.

    • Functionality Limitation

    If any hardware doesn’t support HTML5, then PWAs are not supported in them.

    • Legitimacy Limitation

    Since PWAs aren’t downloaded from a central store, users find it difficult to trust them. Native apps on Google Play Store or Apple’s App Store don’t face this issue.

    • Application Login Support

    One of the primary challenges in the features of PWA is that they don’t yet have the capability to communicate with any other apps installed on your device, unlike native apps, which can easily talk with other apps for tasks like authenticating logins.


    Progressive Web Apps are the ideal way to provide your user with the best user experience on mobile websites.

    Will PWAs kill apps? Right now, this seems like quite a challenge. However, with more and more people becoming aware of the capabilities of progressive web apps, the future looks bright for PWA’s.

    PWA is not only limited to mobile. With the latest integrations and improvements, they can now be implemented on desktop as well. If you’ve ever opened the mobile websites of Pinterest, Instagram, or Tinder on your laptop or PC, you’ve used their PWA version.

    Let us know in the comments section what do you feel about this technology. Do you think PWAs will cause the death of mobile apps in the near future?
