Progressive web apps: A technical overview and analysis of user experience benefits
Exploring the technical features and capabilities of PWAs and their impact on user engagement, performance and SEO
1 of 10: Technical aspects of PWAs and their impact on user experience
One of the most important technical aspects of PWAs is that they can give users a smooth and quick experience. This means that they adapt to the size and capabilities of the device that is being used to access them. This is done with responsive design techniques, which let the app's layout and formatting change automatically based on the size and orientation of the device. This helps improve the UX as a whole by making sure that users have the same high-quality experience no matter how they use the app. [1]
PWAs can provide offline support, which allows users to access the app even when they don’t have an active internet connection. This is achieved through the use of “service workers,” which are background scripts that can intercept network requests and cache data for offline use. This can improve the UX overall by making the app more reliable for users, especially in places where internet access is limited or unreliable. It can also make the app more reliable for users. [2]
In addition to these technical features, PWAs also offer several other capabilities that improve the UX for users. One of these is the ability to be found and installed by users easily, just like native apps. This is done with the help of web app manifest files, which define the app's metadata and how it looks on the home screen of a user's device. This makes it easy for users to find and install PWAs, which can help improve the UX as a whole. [3]
PWAs use modern web technologies like web app manifests, service workers, and a web-app shell architecture to support these technical features. With these technologies, PWAs can work even when the device isn't connected to the internet, send push notifications, and put themselves on the home screen of the device. Also, PWAs use browser APIs like the Fetch API, Cache API, and Background Sync API to offer similar features to those of native apps.
2 of 10: Real-world examples of PWAs
Progressive web apps (PWAs) have been used by a number of companies successfully, leading to more user engagement and sales. Here are some examples of companies that have used PWAs successfully and seen big benefits:
- Alibaba: The e-commerce giant developed a PWA version of its mobile website, called “Alibaba.com Lite”. The PWA version of the site saw a 76% increase in conversions and a 14% increase in the number of monthly active users compared to the native app. Additionally, the PWA version significantly reduced the bounce rate, which means users were more likely to stay on the site and make a purchase. [4]
- Twitter: Twitter developed a PWA named Twitter Lite, which provides a fast and reliable experience for users, even on slow or unreliable networks. Twitter reported that the PWA version of the site saw a 65% increase in pages per session and a 75% decrease in bounce rate compared to the native app. The PWA version also made it easy for users to add the app to their home screen and receive push notifications, which helped improve user engagement. Additionally, it helped to reduce data usage and loading time, which has helped improve the user experience for users in countries with limited internet access. [5]
- The Washington Post: The PWA version of the site has seen a 63% increase in engagement and a 20% increase in ad viewability compared to the native app. The PWA version also allows users to access the site offline and provides push notifications, which has helped improve user engagement. Additionally, The Washington Post reported that the PWA version of the site has seen a significant reduction in data usage and loading time, which has helped improve the user experience for users in countries with limited internet access. The PWA version has also helped the company to expand its reach globally, as it is accessible in countries where the native app isn’t available for different reasons. [6]
These examples show how PWAs can increase user engagement, conversions, and the number of people who see ads. They also show how PWAs can provide a better user experience for users in countries with limited internet access by providing faster loading times and offline support.
3 of 10: The benefits of PWAs and modern web technologies
Progressive web apps (PWAs) are a subset of web apps that use current web technologies to give users an experience similar to that of native apps [1]. PWAs can help users have a better user experience (UX) in many ways by taking advantage of new web technologies.
One of the main benefits of PWAs is that they can provide offline support [5], which allows users to access the app even when they don’t have an active internet connection. This is done with the help of "service workers," which are scripts that run in the background and can intercept network requests and store data for use when the network is down [6]. This makes the app more reliable for users, especially in places where internet access is limited or unreliable.
PWAs also have the advantage of being easy to find and install, just like native apps [1]. This is done by using web app manifest files, which describe the app's metadata and how it looks when it's added to the home screen of a user's device [2]. This makes it easy for users to find and install PWAs, which can help improve the UX as a whole.
PWAs also have the ability to be easily shared through links, which makes it easy for users to share the app with friends and family. This can help increase user engagement and drive more traffic to the app. [7]
PWAs also have the potential to improve performance by loading content faster. PWAs can use techniques such as code-splitting, lazy loading, and pre-caching, to ensure that the app loads quickly even on slower networks. [8]
In addition, PWAs also have the potential to improve SEO, as they can be easily indexed by search engines and shared through links, making it easy for users to find them. This can help increase visibility and drive more traffic to the app. [8]
Overall, PWAs offer a range of benefits that can improve the user experience and drive business growth. They can be used on a variety of devices and platforms, can be used offline, are easy to find and install, and could improve performance and SEO.
4 of 10: Limitations and challenges of PWAs
Progressive web apps (PWAs) have a lot of advantages, but it's also important to know what they can't do and what problems they can cause.
One limitation is browser support. Not all browsers support all the features of PWAs, and some may not support PWAs at all. For example, Internet Explorer 11 doesn't support service workers, which are a key part of PWAs [9]. This means that users who access a PWA on Internet Explorer 11 will not be able to use the offline capabilities of the PWA. This can limit the reach of the PWA and affect the user experience for some users.
Another limitation is the level of control over the user experience. PWAs rely on the browser to provide the user interface, which means the developer has less control over the design and layout of the PWA [10]. This can make it harder to make sure that the user experience is the same across all devices and browsers.
Additionally, PWAs also have some limitations when it comes to accessing the device’s hardware, such as a camera, microphone, geolocation, and other sensors. These limitations can affect the functionality of certain types of PWAs and the user experience [11]. For example, a PWA that relies on access to the camera or microphone may not work correctly on certain devices or browsers.
It’s important to keep in mind these limitations and challenges when developing PWAs to ensure the best user experience possible [12]. PWAs should also be tested on different devices and browsers to make sure they work well and give users the best experience possible.
5 of 10: Guidance and resources for developers
Creating progressive web apps (PWAs) can be hard, but there are a lot of tools that can help developers make high-quality PWAs that give users a great experience.
One example of a resource is the “Learn PWA” provided by Google Developers [14]. This guide tells you everything you need to know about the technical side of PWAs, such as how to make a manifest file, register a service worker, and make a design that fits any screen size. It also has tips on how to make the best PWAs, like how to improve performance and make sure the PWA works offline.
Additionally, there are a number of tools available to help developers create PWAs, such as the Lighthouse tool [15], which is a performance audit tool provided by Google Developers. It can be used to audit the performance of PWAs and provide suggestions for how to improve the performance of the PWA.
Furthermore, there are also open-source PWA frameworks like Angular PWA [16], React PWA [17], and Vue PWA [18], which are widely used by developers to create PWAs and provide pre-configured modules and services to develop PWAs easily. Developers can also find tutorials and guides on various websites and blogs, such as the Mozilla Developer Network [19] and the “Building a better web together” section of the Google Developers website [20].
In conclusion, developers who want to make PWAs have a lot of tools at their disposal. These resources include guides, tutorials, and tools that show you how to make high-quality PWAs that give users a great experience. By using these resources, developers can learn the knowledge and skills they need to make PWAs that work well on all devices and platforms and are optimized for performance.
6 of 10: Cost-effectiveness of progressive web apps (PWAs)
PWAs offer several cost-effectiveness advantages compared to native apps and traditional web apps [21]. PWAs can be made with web technologies, which are usually better known and have a larger pool of developers to choose from. This makes the cost of making a PWA lower. PWAs can also be easily updated and maintained, as they do not need to go through the app store submission process, which can save businesses time and money in the long run.
Another cost-effective advantage of PWAs is the reduced need for separate development and maintenance of native apps for different platforms [22]. PWAs can be used on any device, so companies don't have to make separate apps for different platforms like iOS and Android. This can help businesses save money and resources on development and maintenance costs.
PWAs also have a smaller file size compared to native apps [21], which means that they take up less storage space on the user’s device. This can lead to increased adoption and usage of the PWA, which in turn can lead to increased revenue for the business.
In addition to these cost-effectiveness advantages, PWAs can also lead to increased engagement and conversions [23], which can ultimately result in increased revenue for the business. This can help businesses achieve a better return on investment and grow their online presence.
In conclusion, PWAs are more cost-effective than native apps and traditional web apps in a number of ways. They can be developed using web technologies, easily updated and maintained, and reduce the need for separate development and maintenance of native apps for different platforms. They also have a smaller file size. PWAs can also lead to more engagement and conversions, which can help the business make more money in the long run. Because of these benefits, PWAs are a cost-effective way for businesses to improve their online presence and keep users interested.
7 of 10: Security and user data protection in progressive web apps (PWAs)
Security and user data protection are essential considerations when developing progressive web apps (PWAs). PWAs can have security features like HTTPS encryption to protect the connection between the user's device and the server, as well as ways to verify the user's identity and handle sensitive data [24].
One example of a security measure for PWAs is the use of JSON Web Tokens (JWT) for authenticating users [25]. JWT provides a signed JSON object from the server that can be checked by the client. This makes user authentication safe and quick. This lets the PWA verify the user's identity without making them send their login information with every request.
Another example is the use of IndexedDB [26], a client-side NoSQL database, that allows PWAs to store user data locally on the client device, in a secure and efficient way. IndexedDB makes it easy to store and get data, and it lets PWAs work without an internet connection. It also makes sure that the data stored is encrypted and that only the PWA can access it.
PWAs can also include a feature called Content Security Policy (CSP) [27], which allows the developer to define which sources of content are allowed to be loaded by the PWA, thus preventing malicious code injection and cross-site scripting attacks.
In addition to these security measures, it is also important to have regular security testing and vulnerability assessments conducted on the PWA [28] to ensure that any potential vulnerabilities are identified and addressed in a timely manner.
In conclusion, security and user data protection are critical aspects of PWA development, and it is important for developers to consider and implement appropriate security measures to ensure the protection of user data and the prevention of malicious attacks. By including measures such as HTTPS encryption, JWT, IndexedDB, CSP, and regular security testing, PWAs can provide a secure and safe experience for users while keeping their data protected.

One of the key benefits of PWAs is increased engagement. According to a study conducted by Google [29], PWAs can increase user engagement by up to 150%, with users spending more time on the app and coming back to it more frequently. This can be attributed to the app-like experience that PWAs provide, which helps to keep users engaged and coming back to the app.
Another benefit of PWAs is increased conversion rates. Alibaba [4] did a study that showed that their PWA increased conversion rates by 76% compared to their mobile website. This is because PWAs load faster and can be used without an internet connection. This makes the user experience better and makes it more likely that the user will make a purchase.
PWAs also lead to increased re-engagement rates. A case study by Flipkart [30] found that their PWA resulted in a 40% increase in re-engagement rates and a 70% increase in time spent on the app. This is likely due to the app-like experience and offline capabilities of PWAs, which make it easy for users to access the app and continue using it even when they are offline.
Also, PWAs can increase core engagement metrics like the amount of time spent, the number of searches, and the number of boards made. A case study by Pinterest [31] found that their PWA resulted in a 60% increase in core engagement metrics. This shows how PWAs can make users more interested and improve their overall experience.
In conclusion, PWAs have been shown to have a significant impact on user experience, with several studies and case studies highlighting the benefits of PWAs. PWAs can increase user engagement, increase conversion rates, increase re-engagement rates, and increase core engagement metrics. These benefits make PWAs a powerful solution for businesses looking to improve their online presence and user engagement.
