Start with the required surfaces
Every app launch website should have stable URLs for privacy, support, terms, subscription terms, account deletion, and press. These pages are not filler. They reduce review friction, help customers self-serve, and give search systems clear context.
Make app links boring
Use platform-native app links for real routing. iOS needs Universal Links and an Apple App Site Association file. Android needs App Links and a Digital Asset Links file. Keep custom URL schemes as a fallback, not as the primary public link.
Publish answer pages early
Before launch, write short pages for the problems your app solves, onboarding questions, billing questions, platform limitations, and release notes. Each page should answer one query directly, then link to the next useful action.
Keep the designer surface small
The fastest path to a world-class site is not a large component library. It is a clean content model, a small set of reusable sections, strong imagery, and a brand token file that a designer can transform quickly.
