Being a relatively new development, PWA optimization still leads to positive results in the majority of cases and has amazing statistics. PWA Stats constantly reports about benefits achieved by services that implemented PWA.
PWAs are great helpers when it comes to online marketing. That is why they are popular among the SEO crowd. However, just like React and SEO, the PWA SEO combination has its difficulties. In this article, we will shed light on how PWAs work with SEO.
Examples and Main Benefits of PWA
Any web service can be a PWA. There are three main requirements for that:
- Runs under HTTPS.
- Includes a Web App Manifest.
- Implements a service worker.
The main purpose of PWA is to provide superior functionality for every user. Here is the list of the main advantages offered by PWAs:
- PWA brings new opportunities and growth to literally any business. It combines the best of app and web qualities, being responsive and able to work on any device, and doesn’t necessarily require a speedy network.
- The transport-layer security makes it secure.
- Service worker (a special script that your browser runs in the background) allows PWAs to work in offline mode.
Let’s look at some of the greatest examples of PWA adoption:

The PWA of Starbucks’ ordering system is simple and user-friendly. It looks just like their native app but does have the ability to run offline when a user browses the menu and adds items to the cart. The best benefit of such a solution is the fact that PWA is almost twice smaller than Starbucks’ standard app. Because of that, the company significantly increased the number of web users.
After it was discovered that only 1% of Pinterest mobile users download an app and sign in due to its poor performance, the mobile app was rebuilt on the basis of PWA technology. Thanks to that, indicators such as time spent, ad revenue, and core engagements have increased up to 40% – 60%.
Uber web app was rebuilt as a PWA with an aim to provide fast service on low-speed networks and on old smartphones that aren’t compatible with the native Uber app. Thanks to that, a super-lightweight core app loads in around 3 seconds on 2G networks.
The Importance of SEO
SEO is all about optimizing your website for search engines (SEs). Its main purpose is to improve the website’s ranking in search results and engage visitors. It’s based on SE algorithms and uses keywords to help search engines show relevant content and attract a targeted audience to the websites. This is how SEO can bring organic traffic to your website which is the best of a kind. Unlike direct and paid traffic, it’s able to turn most of your visitors into your clients and customers.
SEO for Progressive Web Apps: What’s the Problem?
Despite all the benefits provided by PWA, many website owners still hesitate to implement the technology. There are two main reasons for that:
- The fear of changing the existing system that already works well.
- Poor understanding of how PWA works with SEO.
Many PWAs are built using JS frameworks that aren’t known for their SEO-friendly nature.
Server-Side Rendering and Client-Side Rendering
Most websites use Server-Side Rendering (SSR). It’s the simplest approach where the page renders on the server-side instead of being rendered in the browser. However, the entire HTML loads every time a user requests the page which may be problematic when the internet connection is not stable or fast enough.
All these make it hard for website owners to both improve the user experience of their visitors and make their content optimized for search engines.
How to Implement PWA Without Losing Your Search Engine Optimization?
1. Apply Dynamic Rendering
2. Combine SSR and CSR
Make sure that the crawler will see the most important parts of the content (that definitely need to be passed through to search engines) using server-side rendering. This information will be picked by the crawler as soon as it discovers the page. The remaining information will be automatically processed via client-side rendering during the second stage of the process.
Our great recommendation is GatsbyJS. It’s pretty easy to build a PWA website using this framework (as well as turn the existing Gatsby website into a PWA). It pre-renders your website in a build step for a brilliant, lag-free performance, even if the internet connection is slow. Thanks to that, your visitors get an app-like browsing experience.
4. Resort to Ready-to-Use PWA Solutions
Today, PWAs are more affordable than ever. So, if you don’t want to waste a lot of time and resources on PWA development, you can use some ready-to-use PWA solutions that are made according to SEO principles and thoroughly tested, so you can be sure of the quality of the code.
5. PWA studio
PWA studio was released in 2019 as a web technology standard designed to provide an app-like experience. In fact, it’s not exactly a ready-to-go solution: it’s rather a collection of tools and features for PWA development. This solution is pretty complex and impressive but requires additional adjustments.
ScandiPWA is an open-source solution, based on React and Redux. It’s designed with the aim to improve websites with speed and the ability to work offline. It also constantly updates, so you will always be getting new functions.
7. Vue Storefront
This is one of the first PWA solutions available on the market. Actually, Vue Storefront is a universal, all-in-one solution, but requires additional maintenance resources.
How to Avoid SEO-Related Mistakes During PWA Implementation?
To develop a well-crafted PWA that will help you win at SEO by providing an improved user experience, you should:
- Perform SEO audit. This will help spot and fix all the SEO-related problems.
- Consult with SEO specialists. When you build your PWA using React (for example), your SEO specialists should know exactly how to combine React and SEO. This way you will avoid most of the possible issues that can appear after implementation.
- Stick to fundamental SEO principles when developing PWA. In the article related to Progressive Web Apps SEO, published by Google, the company gives tips on how to build indexable PWAs. Some of them are as such:
- Each page should be available via a specific URL. Thanks to that, each page will be crawled independently.
- The website should have a responsive design and be optimized for mobile devices.
- Use progressive enhancement. Thanks to that strategy, PWAs work well even on old browsers.
- Check how Google renders your page using Google Search Console on a regular basis. Thus, you will always know when it’s time to upgrade or change something.
- Keep an eye on the page load time. Google measures every page’s speed of load, and if your page’s loading speed slows down, Google will lower it in rank.

The Bottom Line
PWA optimization offers lots of opportunities for online marketing and brings growth to the vast majority of businesses. In fact, the best SEO practice typically applied by PWA is the user-friendly interface: it’s responsive, structured, and renders fast. However, PWAs still don’t give a direct advantage to SEO, and the SEO-related problems are what stop many merchants from implementing PWA to their websites. That is why it’s important to be careful and use different techniques such as dynamic rendering, the combination of SSR and CSR, or ready-to-use PWA solutions. You should also involve SEO specialists in the process from the very beginning.
As you can see, you can make use of both SEO and PWA by successfully combining them. It also should be noted that the PWA is a young, innovative type of software, so improvements are to be expected.
