Notes from Google’s Progressive Web Apps Roadshow

Progressive web apps: a new level of caring about the quality of your user experience

It’s not about a particular bit of technology (though there’s a few good ones), but about creating a web experience thats as seamless as native applications

User experiences need to be:

  1. Reliable (fast to load, never down offline, even if the network is down). Homescreen.
  2. Homescreen: Auto adding to home screen
  3. Performant (around 3 seconds, 20% of your users will have abandoned your experience. After 3 seconds, 40% of users abandon the site). Immersive
  4. Immersive: full screen, theming, orientation
  5. Engaging.
  6. Notifications: push notifications are what turn meh users into daily users
  7. Option to add a website to your home screen. It starts with a splash screen in case you’re offline. And then it runs like an app, doesn’t show a url

User acquisition costs: 4 ueros on app and .35 cents on web

Great for conversion too, getting users to become frequent visitors. After releasing progressive web app.

  1. Making it reliable and fast so that it loads instantly, even offline.

60% of world-wide mobile connections are 2G

TLS false start removes some of the latency.
