Progressive Web Apps: The Future of Mobile Websites

There’s a moment when you realise your mobile site isn’t quite cutting it. Maybe it loads slowly. Perhaps it looks fine, but feels clunky. Or maybe, and this is harder to spot, users just aren’t sticking around. We’ve seen it happen. And we’ve spent a lot of time trying to fix it.

That’s where Progressive Web Apps come in. They’re not new, exactly, but they’ve quietly become one of the most practical ways to build mobile experiences that actually work. Fast, installable, offline-friendly, they sit somewhere between a website and an app, and they’re changing how businesses think about mobile.

This isn’t a tech deep dive. It’s more of a reality check. If you’re still relying on traditional mobile sites or chasing performance with AMP mobile pages, it may be time to reconsider your approach. Because what worked five years ago doesn’t always hold up now, especially when users expect more and patience is thin.

What Actually Is a Progressive Web App?

Technically, a PWA app is a website that behaves like a native app. It loads fast, works offline, sends push notifications, and can be installed on your home screen. However, unlike native apps, it’s built with standard web technologies, HTML, CSS, and JavaScript and runs in your browser.

The magic happens through service workers (which handle caching and background tasks), a web app manifest (which defines how the app appears), and HTTPS (which ensures security). It’s not flashy tech, but when it’s done right, it feels seamless.

We’ve seen brands like Twitter, Spotify, and Pinterest lean into PWAs. They’re not just experimenting; they’re rebuilding core experiences around them. And it’s not just big tech. Retailers, publishers, and local businesses are starting to ask: Should our following site be a PWA?

AMP vs PWA: A Quick Detour

Before PWAs took centre stage, there was AMP, Accelerated Mobile Pages. AMP was Google’s answer to slow-loading mobile content. It stripped down pages to their essentials, prioritising speed above all else. And it worked. Sort of.

AMP mobile pages load fast, especially in search results. They’re great for news articles, blog posts, and static content. But they’re rigid. Customisation is limited, and interactivity suffers. You can’t build a full eCommerce experience with AMP. Not really.

AMP websites still have a place, especially for publishers chasing visibility. However, for businesses that want engagement, swipes, taps, and conversions, PWAs offer more. They’re flexible, immersive, and better suited to modern UX expectations.

That said, it’s not always a binary choice. Some developers combine AMP and PWA features to create hybrid experiences. It’s messy, but sometimes that’s what works.

Why PWAs Feel Different (And Why That Matters)

There’s something psychological about PWAs. They feel intentional. When a site loads instantly, responds smoothly, and offers offline access, users stay longer. Bounce rates drop. Conversions rise. It’s not just about speed, it’s about trust.

We’ve had clients ask why their mobile site feels “off” even though it’s technically responsive. Often, it’s because the experience lacks cohesion. A progressive web app solves that by behaving predictably, even under poor network conditions.

And yes, there’s a learning curve. Building a PWA takes planning. You need to think about caching strategies, fallback content, and how the app behaves when offline. But once it’s live, the payoff is real.

SEO and Discoverability: Are PWAs Search-Friendly?

This part gets tricky. PWAs rely heavily on JavaScript, which can complicate indexing and search. If search engines can’t crawl your content properly, rankings suffer. However, that doesn’t mean PWAs are bad for SEO; it just means they require careful implementation.

Structured data, server-side rendering, and clean URLs help. So does testing, lots of it. We’ve seen PWAs rank well when built with SEO in mind. And with Google’s mobile-first indexing, performance and usability are more important than ever.

For businesses exploring SEO services in Manchester, it’s worth asking your agency how they handle PWAs. Not every developer understands the nuances of SEO. And if you’re comparing affordable SEO packages, make sure technical optimisation is part of the deal, not just keyword stuffing.

When Should You Build a PWA?

Not every site needs to be a PWA. If you’re publishing static content, articles, press releases, or documentation, a fast, responsive site might be enough. Or even AMP, if visibility is the priority.

However, if you’re building something interactive, such as a booking system, a product catalogue, a member portal, or a PWA app, it makes sense. It offers the speed of AMP with the flexibility of native apps. And it’s future-proof. Sort of.

We’ve worked with clients who started with a basic site and gradually added PWA features. Offline access, installability, push notifications: each layer adds value. You don’t have to go all-in from day one.

Real-World Considerations (The Messy Bits)

PWAs aren’t perfect. Browser support varies. iOS has quirks. Analytics can be harder to track. And users don’t always know what a PWA is; they just want things to work.

We’ve had moments where a client’s PWA felt amazing on Android but clunky on Safari. Or where push notifications didn’t behave consistently. It’s frustrating. But it’s also part of the process.

That’s why planning matters. Define your goals. Test on real devices. And don’t assume users will behave the way you expect. They won’t.

The Future of Mobile Websites

It’s tempting to say PWAs are the future. And maybe they are. However, the web is messy, and trends are constantly shifting. What matters is building experiences that feel fast, intuitive, and trustworthy, regardless of the tech stack.

Progressive web apps offer a way forward. They bridge the gap between websites and apps, giving users the best of both worlds. And for businesses, they offer flexibility, performance, and long-term value.

If you’re rethinking your mobile strategy, PWAs deserve a serious look. Not just because they’re trendy, but because they solve real problems. And in a landscape where attention is scarce, that’s worth investing in.

Frequently Asked Questions About Progressive Web Apps

What is a Progressive Web App (PWA)?

• A Progressive Web App is a website that behaves like a native app. It loads quickly, works offline, and can be installed on a user’s device, all without needing to visit an app store.

How is a PWA different from a traditional mobile website?

• PWAs offer app-like features, including offline access, push notifications, and smoother interactions. Traditional mobile sites may be responsive but often lack these capabilities.

Can PWAs improve SEO performance?

• Yes, if built correctly. PWAs can enhance mobile usability and load speed, which are key ranking factors. However, they require careful implementation to avoid issues with indexing and crawlability.

Is AMP still relevant with PWAs becoming popular?

• AMP mobile pages remain useful for delivering fast-loading static content, particularly in news and publishing. But PWAs offer more flexibility and interactivity, making them better suited for dynamic websites and apps.

Do PWAs work on all devices and browsers?

• Most modern browsers support PWAs, but behaviour can vary, especially on iOS. Features like push notifications and installability may be limited depending on the platform.

Should my business choose a PWA or an AMP website?

• It depends on your goals. If speed and visibility are the top priorities, AMP might be sufficient. If you need deeper engagement and app-like functionality, a PWA is likely the better fit.

Are PWAs expensive to build?

• Not necessarily. Costs vary based on complexity, but many agencies offer affordable SEO packages that include technical audits and PWA planning. It’s worth discussing options with your provider.
