What makes a PWA?

Enhance discoverability through indexable, linkable PWAs.

SEO Ready & Compliant

PWAs are SEO-ready & SEO-compliant through their use of modern JS technologies, such as pre-rendering. Major search engines now advocate the use of PWAs in place of traditional websites or web apps due to their improved performance in key web vitals when implemented correctly.

Reduced Ad Spend

An increased capability for indexing & organic search has potential to reduce advertising spend by allowing marketing teams to shift efforts to more sustainable means of organic discoverability. Leveraging the indexable nature of PWAs caters to more sustainable means of long-term marketing.

Heightened Discoverability

Because PWAs are served & distributed over the web—rather than through a closed App Store—they're able cater to search engines & other means of organic discoverability (such as via social). PWAs can now boast better levels of discoverability than traditional websites & native apps.

Organic Ranking

Combining the indexable nature of PWAs with significant speed optimizations positions apps for greater organic success. The development approach to Progressive Web Apps favors key search engine metrics, such as pagespeed and user-centric implementation.

Linkable In-App Content

Unlike native applications, Progressive Web Apps are fully linkable—which fosters greater levels of engagement through social sharing. With the ability to link to in-app content directly, brands gain additional flexibility in the marketing & sharing of relevant and contextual content to end users.

Sharable PWAs

Progressive Web Apps can be distributed more easily and through a wider range of means when compared to native apps. Direct links, QR codes, social media interaction and other means of sharing enable PWAs to benefit from enhanced discoverability through sharing.

Progressive Web Apps are able to leverage organic discoverability and social interaction at a rate superior to native apps—PWAs are served via the web, even if installed on the users' device. Their linkable, indexable nature allows for greater discoverability without App Store restrictions.

Organic reach potential

PWAs and Headless

PWAs leverage the power of headless architecture in order to source and deliver content to end users. A headless approach involves decoupling a backend CMS (or ecommerce platform) from an application frontend, which allows the backend (where data is stored) to operate independently of the frontend. Headless frontends are most often implemented as Javascript web apps, or — you guessed it — PWAs.

Headless architecture works so well with PWAs that it’s the standard for implementing data sourcing in any progressive web app.

PWAs and Jamstack

Good Progressive Web Apps utilize a Jamstack approach to their implementation, which focuses on separating the overall solution into three key layers or components: Javascript (the frontend), API (integrations to allow data to be sourced from one or multiple backends or databases), and markup (how content is rendered and displayed to end users).

Jamstack principles aim to make the web a better place, by encouraging a more component-focused approach to web and application development.

PWA Development Services

We build interactive PWAs to deliver UX-first web experiences.

We develop high-performance Progressive Web Applications with a focus on user experience and scalability. Through the use of deep integrations and the use of next-generation technology, we're able to deliver rich user experiences that deliver on all key metrics.

PWAs are taking the web by storm, as an innovative new way to deliver an experience that is similar to that of native apps, but with a faster development cycle, reduced ongoing costs, and a significantly easier maintenance process.

PWA stands for “Progressive Web Application”. It’s an innovative approach to application development that favors device-agnosticism over native OS support. Put simply, PWAs aim to solve the problem of developing multiple versions of the same app for different devices or operating systems.

Think of a mobile app: Traditionally you would develop several versions of the application, one for iOS, another for Android—and potentially a couple more for macOS and Windows if you later wanted to expand the experience to desktop devices. The process of developing and maintaining these separate apps is inefficient and costly. That’s where PWAs come in. With Progressive Web Apps, you only develop one version of the application, which is device-agnostic and works the same for all operating systems.

This approach saves thousands in development costs, and allows the gained time and resources to be reinvested elsewhere.

Therefore, PWAs are now the first choice when planning for the development of a new app: whether for mobile, desktop, or other web enabled devices. In fact, Progressive Web Apps are now accepted on all major app stores. Furthermore, because of the technology PWAs are built on, they don’t even require distribution via an App Store, and can be installed independently via a web browser.

The foundations of PWAs lie in JavaScript: a powerful frontend language which is able to deliver rich experiences and power modern web apps.

Over the last few years, Progressive Web Applications have become a well-adopted alternative to developing native apps, due mainly to their rapid development cycle, ease of maintenance, and significantly lower financial overhead.

While there’s still a place for native apps, more businesses than ever are choosing to utilize PWAs to deliver engaging and interactive experiences to their users.

PWAs are web applications, and therefore differ from native applications. Native apps are built for specific devices or operating systems (such as iOS, Android, Windows, or macOS). PWAs, on the other hand, utilize a single JavaScript code base to deliver an identical experience on any device.

Progressive Web Apps are a modern alternative to native apps. They come with a range of benefits above native apps, and can be leveraged to suit particular business needs. Primarily, PWAs are faster to develop, easier to maintain, and cheaper to build.

PWAs offer a far-greater level of interaction with a users’ browser or operating system than an ordinary website. For example, PWAs are capable of delivering push notifications and storing data on the client side, allowing offline access. Standard websites aren’t able to offer these kinds of highly-integrated functionalities, and therefore PWAs are able to deliver more enhanced user experiences, allowing greater accessibility of content, as well as ease of access.

More on PWAs

It's possible to convert (or redevelop) an existing native app or website into a Progressive Web App, potentially in a short space of time. For apps or websites that are already utilizing modern rendering techniques and headless infrastructure, converting to a PWA is relatively straightforward. However, for older websites or apps which run on dated technology, the process would naturally be more involved, potentially requiring redevelopment of the website/app as a new build from the ground-up.

It's definitely worth reimplementing an existing website or native app as a PWA in order to leverage the unique value proposition that Progressive Web Apps provide. For websites, it's a no brainer, and for native apps this step can also be beneficial from a resource and cost perspective.

The length of time it takes to develop a PWA varies greatly depending on the project and its requirements. In general, most new build PWAs take several months from the start of a project to completion. The larger, more complex the application, the longer the development time. Bear in mind that as with all development, PWA feature development can occur in stages or cycles, with iterative releases to enhance functionality. As the maintenance and development process for PWAs is significantly easier than for native apps, development can occur at a much faster pace.

PWAs are built on Javascript and therefore source data from an external location, such as a headless CMS, ecommerce platform, or publishing application. This sourcing of data occurs through integration of the Progressive Web App with an API to retrieve data. In this sense, all PWAs sourcing data from an external database are "headless": as the backend data point is decoupled from the PWA frontend. The headless approach to web and application development comes with many benefits, such as greater security, optimized speed, and a better ability to scale.

Web Apps are browser-based applications, most often built on Javascript, which feature highly interactive experiences and enable users to engage with a User Interface capable of delivering feedback to them in real-time. PWAs boast all the features of an ordinary Web App, plus the offline accessibility. With PWAs, users are able to remain in connection with your app, with data refreshing if necessary once their internet connection is reestablished. This opens up powerful possibilities for many businesses who are looking for a way to reliably deliver content to end users and make the features of their application available regardless of a users' whereabouts. Offline access enables end users to engage with your app more of the time, and reduces barriers for consumers to interact with your content.

Absolutely! Progressive Web Apps are superior to traditional websites in many ways, and should be viewed as a practical approach to upgrading or replacing a website with a modern, future-proof alternative.

It's likely that many websites will become PWAs in the future: And some of the most prominent websites today are already PWAs, such as Twitter and Netflix.

PWAs offer a greater level of integration with a users' browser and operating system than a traditional website does, and additionally allow users to access content offline whilst continuing to engage with certain features of the website.
