A good approach is to design it as a marketing-first site with an app-ready foundation.
Recommended structure
- Public marketing site: fast, responsive, SEO-friendly pages
- Auth/portal area: a separate section for future app features
- Shared design system: reuse the same UI components across both
Why this works
- You can launch the marketing site quickly
- Future app features won’t require a full rebuild
- Keeps performance and SEO strong for the public pages
Practical setup
- Use a framework like Next.js, Nuxt, or Remix
- Keep marketing pages in the main route set
- Add later app features under routes like:
/app/dashboard/account
- Build reusable components now:
- buttons
- navbars
- cards
- forms
Responsive considerations
- Mobile-first layout
- Flexible grids and breakpoints
- Optimized images and lazy loading
- Sticky navigation for smaller screens if needed
Future-proofing tips
- Set up authentication early, even if unused at launch
- Use a component library or design tokens
- Separate content/data from presentation
- Plan for role-based access if app features may grow
If you want, I can suggest:
- a site architecture
- a tech stack
- a starter folder structure
