Server-side rendering and SEO

Short summary

Rendering strategy determines whether search crawlers and AI assistants see your content or a blank HTML shell. SSR and SSG deliver complete HTML on first request, while CSR delays content until JavaScript executes, causing fragile indexing, broken social previews, and poor AI crawler compatibility. The best approach mixes strategies per route: SSG for stable pages, SSR for dynamic content, and ISR for large catalogs that update periodically.

• •CSR sends blank HTML to crawlers; SSR and SSG deliver complete content immediately
• •Google's two-wave indexing and most AI/social crawlers handle JavaScript poorly, making server rendering essential for visibility
• •Mix SSG, SSR, and ISR per route based on content stability and personalization needs
