What is a PWA Audit?

The objective of a PWA audit is to examine aspects of your ecommerce platform to ensure it meets the criteria for being a well-functioning Progressive Web App. The PWA audit checks the following areas in your ecommerce:

Fast and reliable: The PWA audit ensures your ecommerce performs well even on slower mobile networks. Additionally, it assesses whether your site offers offline functionality, ensuring users can access its content even without an internet connection.

Installable from the browser: The PWA audit examines if your web app can be installed on multiple device types, for a seamless experience across various platforms. It also verifies whether your ecommerce website utilizes native app features such as push notifications.

Accessible: The PWA audit also checks to make sure that your ecommerce website is accessible to all users, including those with disabilities, by following web accessibility guidelines.

Follows web development best practices: The PWA audit verifies that your ecommerce platform is secure, responsive, and uses modern web capabilities to provide an optimal user experience.

What does PWA stand for?

PWA stands for Progressive Web App. It is a web application that combines the best characteristics of traditional web applications and native mobile applications. PWAs are built using web-based technologies like Java, HTML, CSS, etc., and are accessible through a web browser. The best thing about such apps is that you do not need to download a separate app from an app store, and they can be accessed offline. We will get into more details of the benefits in the next section.

Why perform a PWA audit?

In general, performing a PWA audit is crucial for ecommerce businesses as it helps identify areas of improvement that can enhance the overall user experience. Here are some of the advantages that a PWA audit offers:

Faster performance 

This is one of the most obvious benefits: PWAs are designed to be lightweight and optimized for performance. The PWA audit in Lighthouse evaluates various performance metrics, such as first meaningful paint and time to interactive, helping ecommerce websites identify performance bottlenecks and optimize their PWA to provide faster and more responsive experiences to users.

Personalized user experience

The PWA audit also helps identify areas where improvements can be made to offer a more personalized user experience. For example, it checks the custom splash screen configuration – by setting one up, you can provide your users a more branded, engaging experience. 

Optimized security

The PWA audit puts a spotlight on the security of your ecommerce website, ensuring that it transitions from HTTP to HTTPS. By redirecting traffic to HTTPS, your online store is shielded from intruders attempting to tamper with or intercept communications between your site and its users. Additionally, HTTPS enhances your site’s credibility in the eyes of both users and search engines, as it is now considered a standard security practice.

Note: If your page is already running on HTTPS but you’re failing this audit, you may have problems with mixed content.

Better SEO

The PWA audit also evaluates other factors such as loading speeds, responsive design, and offline accessibility that contribute to improved SEO rankings. By complying to PWA standards, your ecommerce can automatically achieve higher visibility and organic traffic.

Improved mobile accessibility

The PWA audit helps ensure that an ecommerce site offers a responsive and mobile-friendly experience across different devices and screen sizes. It verifies that your site content renders correctly for the corresponding viewport. In addition, the audit checks that basic content and web page functionality do not rely on CSS or JavaScript, ensuring that your site is accessible to the largest possible audience.

Offline functionality

The PWA audit ensures that a site’s content and functionalities are available to users who are offline or in low-connectivity environments. This capability is particularly valuable for ecommerce websites as it allows users to continue browsing products, etc.

App-Like Feel and Discoverability

Another benefit of having a PWA for your ecommerce is being able to provide an app-like experience without the need for users to download and install a separate application. The PWA audit helps ecommerce websites optimize their PWAs to have an app-like feel in terms of navigation and interactions.

What is the PWA audit in the Lighthouse report?

The Lighthouse report is provided by Google that helps developers evaluate their web applications according to various criteria such as performance, accessibility, SEO, PWA, and best practices, giving you suggestions for improvement. The Google Lighthouse tool is available within the Chrome browser developer tools, which can be accessed by pressing F12. 

The PWA audit in Lighthouse is one of the best resources for performing the audit for your ecommerce. Valido AI provides easy access to Lighthouse through its integration of the tool, and also recommends optimization steps for PWA issues identified in the report.
