A bakery owner we worked with a few years ago asked a simple question: “Do I need an app?” Her customers kept saying they wanted to reorder their usual Saturday box from their phones, but a native app meant roughly two app stores, two codebases, and a budget she didn’t have. What she needed was something that felt like an app without the baggage. That’s the pitch for progressive web apps, and it’s a reasonable one. It’s also oversold fairly often.
So let’s look at what a PWA actually is, what it can and can’t do, and how to decide whether it’s worth your money.
What a progressive web app really is
A PWA is a website built with a few extra technologies so it behaves more like an installed app. It still lives at a normal URL and is found through search, but visitors can add it to their home screen, open it full-screen, and in many cases use parts of it with a weak connection or none at all.
Three pieces make that happen:
- A web app manifest, a small JSON file that tells the browser your app’s name, icons, and colors.
- A service worker, a script that runs in the background, caches key files, and decides what to serve when the network is slow or gone.
- HTTPS, which is required. Service workers won’t run on insecure pages.
Google’s own documentation at web.dev/learn/pwa is the best neutral explanation of these building blocks, and it’s worth a read before you talk to any developer about this.
Where PWAs genuinely help
The honest benefits are practical rather than magical.
One codebase, every device. You build once and it works on Android, iOS, Windows, and desktop browsers. For a small business, that alone can cut build and maintenance costs substantially compared with separate native apps. We won’t quote a percentage, because it depends entirely on the project, but the difference is real.
Faster repeat visits. Because a service worker can cache your shell (header, styles, core scripts), return visitors often see pages load almost instantly. If you’ve been working on Core Web Vitals, this pairs well with that effort. You can measure the effect in PageSpeed Insights and in the Core Web Vitals report inside Google Search Console.
No app store gatekeeping. You can ship an update by deploying it. There’s no review queue, no 15-30% store commission on digital purchases, and nobody can pull your listing.
Resilience on bad connections. This matters more than people expect. A field-service team in a basement, a customer on a train, a shopper in a patchy-coverage market: an offline-capable page that still shows the menu, the booking form, or yesterday’s order history keeps people from bouncing.
Where they fall short
Here’s the part that sales decks skip.
iOS support is still more limited than Android. Apple has improved things over the years, including web push notifications for home-screen web apps, but behavior differs between browsers and OS versions, and some capabilities (certain background tasks, deeper hardware access) remain restricted or inconsistent. Always test on real iPhones, not just a desktop emulator.
They’re not a replacement for every native app. If you need heavy 3D graphics, advanced Bluetooth interactions, or tight integration with phone features like contacts and health data, native is probably the right call.
Discoverability isn’t automatic. A PWA is still a website, so it needs the same SEO groundwork as any other. Making it installable doesn’t make it rank. If search traffic matters to you, make sure content is crawlable and rendered properly, something Google explains in its JavaScript SEO basics guide. Pages that depend entirely on client-side rendering can cause indexing headaches.
Caching bugs are sneaky. A badly written service worker can serve stale pages for days. We’ve seen a client’s price change fail to appear for returning visitors because the old version was cached too aggressively. Good PWA work includes a clear update strategy and a way to force a refresh.
A quick decision framework
Skip the buzzwords and ask these questions:
Do your customers come back often?
Reorders, bookings, account dashboards, loyalty programs, and tools people use weekly are good PWA candidates. A five-page brochure site visited once before a phone call is not.
Is connectivity a real problem for them?
If your audience regularly works or shops on unreliable networks, offline support has genuine value. If everyone’s on office broadband, it’s a nice extra at best.
Would you otherwise build two native apps?
This is where PWAs shine. If the alternative is a six-figure native project for an audience that mostly wants to browse, check status, and place orders, a PWA is probably the smarter first step. You can always build native later if usage proves the demand.
Is your current site already fast and mobile-friendly?
If not, fix that first. A PWA built on top of a slow, cluttered site just gives you an installable slow site. Sometimes a well-optimized responsive site gets you 80% of the benefit for 20% of the effort.
Quick answers
Does a PWA cost more than a regular website? Usually yes, modestly. You’re adding service worker logic, offline design, and more testing. It costs far less than separate native apps, but it’s not free on top of a basic brochure site.
Will a PWA improve my Google rankings? Not directly. Google doesn’t rank a site higher just for being a PWA. Any benefit comes indirectly, through better speed and user experience, and no honest agency can promise a specific ranking or traffic result.
Can I turn my existing WordPress site into a PWA? Often, yes. Plugins and custom service workers can add basic installability and caching. For anything with logins, carts, or personalized data, though, custom development is safer than a one-click plugin, because caching the wrong thing can expose or break user-specific pages.
Where we’d start
If you’re curious but unsure, begin with an audit rather than a build. Run your site through Lighthouse in Chrome DevTools, which includes a PWA-related check set, and note what’s missing. Then look at your analytics: how many visitors return, what share are on mobile, and where do they drop off? Those numbers will tell you more than any trend article, ours included.
A PWA can be a smart, economical middle path between a plain website and a full native app. It’s just not the right answer for everyone, and a good developer will tell you so before taking your deposit.
