Answer

Do PWAs improve conversion rate?

Short answer

Yes, when users actually install. Published case studies (Alibaba, Twitter Lite, Pinterest, Uber, BookMyShow) show 30-100% conversion lift after PWA adoption — driven by faster loads, offline support and home-screen install. The effect is largely from install: once your icon sits on the home screen, return sessions jump.

Where the lift comes from

Two levers: (1) faster loads (service-worker cache) improves same-session conversion, and (2) home-screen install shortens the path to return visits, which are always higher-intent than first-touch.

The install is the unlock

A PWA without installs performs the same as a mobile website. The measurable ROI comes from the install rate — which is what a well-timed install prompt drives.

Realistic expectations

Expect 3-8% install rate on mobile with a well-timed prompt, and 20-40% higher LTV for installed users vs anonymous mobile visitors.

What is a PWA?

A PWA (Progressive Web App) is a regular website that meets three technical criteria — HTTPS, a Web App Manifest and a service worker — so browsers let visitors install it on their home screen. Once installed, it launches like a native app, works offline and can send push notifications.

Why is my PWA install prompt not showing?

Chrome shows the install prompt only when the site passes strict installability criteria: HTTPS, a valid manifest with name, icons and start_url, a registered service worker with a fetch handler, and the user has not previously dismissed the prompt. Any one of these missing is enough to block the prompt entirely.
