Progressive Web Apps

These hybrids of traditional websites and mobile apps can be indexed by Google just like any normal website. At the same time, the content can be used as a native application and available on all platforms. In the future, PWAs are likely to play an important role in mobile optimization. PWAs date from an initiative supported by Google.

What are progressive web apps?

Progressive Web Apps (PWAs) are app-like websites that can be accessed via a browser on mobile devices. Progressive Web Apps have all the benefits of native apps without having to install them on the user's device. Plus, Progressive Web Apps are easier to build, explore, and visit.

Why use Progressive Web Apps?

There are several ways that webmasters can make their content available to mobile users. One way is to optimize your website for mobile devices by implementing responsive design. When this option is selected, all content can be viewed on almost any device, as the website adapts to the screen size and characteristics of the device it is loaded on. Other webmasters prefer to use native applications. These are separate programs (applications) that can be installed on a tablet or smartphone from the application library (App Store on iOS, Play Store on Android, Microsoft Store on Windows). These native apps are not offline programs that display content from the web, but rather closed systems that typically have no direct connection to search engines.

In recent years, Google has responded to the development of closed web systems, for example by enabling application indexing. This allows Google to access and index the app's URLs. Now when a user searches on Google, they can see results for apps if they are already installed on their device. The app download page in the App Store may also be available as a mobile search result.

Google has supported the Progressive Web Apps initiative with the goal of making as much web content as possible, especially in terms of searchability, accessible to search engine crawlers. This combination of apps and websites is part of Google's principle of incremental improvement, which means that websites should not offer different functionality for different user devices, but should always respond and adapt to the respective customer. Part of this is that Progressive Web Apps must continue to take into account the specificities of mobile internet use without having to install a separate app.

Progressive Web Apps should enable users to:

Access content on any device
Access web content even if the internet connection is weak or unavailable
Fast web page loading
Enjoy a high-quality user interface

Google defines the key features of Progressive Web Apps as follows:

PWAs are reliable because they download content even if the connection is weak or not sufficient for normal internet use.
PWAs are also very fast as they respond immediately to user input. This almost completely eliminates page load or scrolling delays.
Finally, PWAs provide a simplified user interface that mimics native apps.

How do progressive web apps work?

Service Workers are the foundation on which Progressive Web Apps are built. These are JavaScript files that allow cached content to be loaded in the background. This JavaScript works offline and does not require an internet connection. Another advantage of service agents is that delays in calling another page are almost completely eliminated.

The spectrum of service personnel goes even further. When developing a progressive web application, the service worker's tasks are defined and saved as a script. Allows you to configure entire software processes that depend on certain events and perform predefined actions. Therefore, it is possible to create a PWA to download content even before the link is clicked.

In order for a progressive web app to work in any browser, it needs something called an app skin. This ensures that a mobile representation of the URL is generated and that the app adapts to the functionality of the browser used. The application skin is also responsible for styling the PWA to reflect the look and feel of the original application. This means that the application shell is the basis for dynamic loading of content. It is loaded into the device cache when the PWA is called.

The third important part of PWA is the manifest of the web application. This is a JSON file stored on the server. This manifest file allows the user to register the called PWA on their device as a native application. In fact, not the entire application is installed, as would be the case with a native application, but only the basics in the form of (at least) the application shell. The web app manifest allows the PWA registration icon to be placed on the home screen. You can also specify whether the app can be downloaded without a browser or in an available browser. A script can also be used to control the appearance and/or functionality of an application. Finally, you can enable push notifications for users as long as users agree to this functionality during application installation.

What are the advantages of Progressive Web Apps?

Progressive Web Apps offer webmasters many advantages:

It is much more profitable to develop a PWA than a native application.
Maintaining a PWA does not require much effort.
PWA can be continuously updated.
No dependency on app stores. Webmasters can promote their own PWAs.
Progressive web app content can be indexed and ranked in search engines.
There are no platform restrictions. This means that users can view PWA content on any mobile device.
Web content is available on almost any connection quality.
The connection between the user and the web content is improved by installing a PWA.

Why does Google love Progressive Web Apps?

It's no surprise that Google is encouraging the use and adoption of Progressive Web Apps, as much of the mobile web is accessed through smartphone apps. This means that search engines like Google only have limited access to user data and, in particular, app content cannot be fully crawled. With Progressive Web Apps, Google and other search engines have the ability to collect user behavior data even while using the apps. At the same time, it is possible that PWA could also be used to serve Google ads. So PWAs become an additional market for Google to generate revenue.
