SSR vs ISR for marketing sites: what we actually use

When to choose ISR, when SSR is required, and how to avoid stale or expensive rendering paths.

Problem context

Teams overuse SSR and pay performance costs or overuse static generation and miss freshness.

Approach

Segment routes by freshness and interaction criticality, then apply SSR or ISR deliberately.

Implementation

  • Use ISR for landing/listing/detail pages with stable content
  • Use SSR/no-store for contact, tokenized, or highly dynamic endpoints
  • Trigger on-demand revalidation from CMS publish events
  • Add cache headers and monitor stale content paths
