A Progressive Web App (PWA) is a website with superpowers. A regular site requires an internet connection for you to access it but a PWA can be accessed with or without an internet connection (assuming you’ve visited the site before).
The core idea behind PWAs is to make a site or web app always accessible, regardless of the network conditions for the device. It’s an ambitious goal and is becoming a reality thanks to resources that are being poured into it from Google.
Google has fully supported PWAs since Chrome 57, and they’ve been discussing it at webmaster and marketing conferences for at least a few years now. In 2018 they significantly increased their messaging and resources related PWAs. At their 2018 Chrome Dev Summit, PWAs were on full display. They even debuted an image editing web app called Squoosh that could be used offline.
If you’re an SEO or webmaster, then you’ve probably seen mentions of PWAs everywhere. When you use the current version of Google Lighthouse, there’s even a dedicated score for PWAs. When you visit Google’s Web Development site, there’s a promoted and dedicated section for Progressive Web Apps. PWAs are a big deal to Google, and they’re betting part of their future on it.
