The Next.js App Router brings a powerful model for building fast, SEO-friendly React apps — but it comes with new mental models around rendering and caching. Here’s a practical look at running it in production.
Choose the right rendering strategy
Static generation for marketing and content pages, server rendering for personalized or fast-changing data, and client components only where interactivity is needed. Mixing these correctly is where the App Router shines.
Caching is powerful — and surprising
The App Router caches aggressively by default. Understanding the fetch cache, route segment config, and revalidation (ISR) is essential to avoid serving stale data — or accidentally leaking dynamic content into static pages.
SEO that actually works
- Use the Metadata API for titles, descriptions, and Open Graph tags
- Generate sitemaps and structured data (JSON-LD)
- Optimize Core Web Vitals with next/image and font optimization
Done well, Next.js gives you near-instant pages that rank. See the full stack we work with.
