Picking a rendering strategy per route, not per project
The most common mistake we see in existing Next.js codebases is treating rendering mode as a single project-wide decision. It is not. A marketing homepage, a product catalog and an authenticated settings page have different freshness and performance needs, and the App Router lets each route pick independently.
Static generation fits pages where content changes rarely: about pages, legal pages, most marketing copy. Incremental Static Regeneration fits pages backed by content that changes on its own schedule, like a product catalog or a blog, where a stale page for a few minutes is an acceptable trade for near-static load speed. Full server rendering fits pages that must reflect the current request, like a personalized dashboard or search results with query parameters. Getting this mix right, route by route, is most of what separates a fast Next.js site from a slow one.
