How to tell what you need
If visitors mainly need to understand services, geography, and credibility—and convert via call or form—a structured marketing site plus landing pages is usually enough. That stack prioritizes SEO, speed, and trust sections.
If users must log in, save progress, manage records, or collaborate across roles, you are in web application territory. Expect product decisions: authentication, auditing, releases, and integrations. Hybrid projects layer marketing surfaces on top of logged-in tools; plan URLs and internal links so both sides stay crawlable where public.
Side-by-side signals
- Website: broad discovery, content hubs, fast contact paths.
- Web app: sessions, permissions, transactions, and repeated tasks.
- Custom software: internal-first systems that may never be indexed—still link them from service pages for clarity.
- SEO focus differs: public pages need indexable copy; apps need strategic landing pages that explain value.
