PWAs Are Cool. But Can Google Actually Index Them?
Progressive Web Apps blur the line between websites and native apps. They are fast, work offline, and can be installed on the home screen.
The SEO question is simple: can Google crawl and index them properly?
The Answer
It depends on how they are built.
If your PWA uses server-side rendering and serves real HTML to crawlers, Google can index it just fine. The PWA features (service worker, manifest, offline support) are layered on top and do not interfere with crawling. The same principles from our JavaScript rendering issues post apply here.
If your PWA is a pure client-side SPA with an app shell that loads everything via JavaScript... same problems as any other client-side rendered site.
Best Practices
Server-side render your content. Use the app shell model for the UI, but make sure content is in the initial HTML response. Implement proper routing — no hashbang URLs. Make sure your service worker does not cache stale content for crawlers.
The Bottom Line
A PWA is not inherently good or bad for SEO. It is the rendering strategy that matters. SSR + PWA features = best of both worlds. Check our JavaScript framework comparison for which frameworks handle this best. Google's Web Vitals documentation can help you measure your PWA's real-world performance.
