Website vs web app vs PWA
| Website | Web app | PWA | |
|---|---|---|---|
| Main purpose | Inform and convert | Let users do tasks | App-like use in the browser |
| Login | Usually no | Usually yes | Optional |
| Offline use | No | Rarely | Yes |
| SEO | Core goal | Public pages only | Needs care |
How success is measured
Every engagement reports on a small set of numbers agreed at the start, so progress is visible and comparable month to month:
- Hours of manual work saved
- User adoption
- Performance and uptime
- Defects after release
- Conversion or revenue impact
