When should a B2B website use SSG vs SSR?

Use SSG (and ISR) for all public marketing pages, service hubs, blog articles, and documentation; reserve SSR for authenticated, user-specific portal dashboards.

How does Incremental Static Regeneration (ISR) handle CMS updates?

When an editor publishes an update in the headless CMS, a webhook triggers on-demand revalidation of that specific URL in seconds without a full site rebuild.

How is this implemented across Vezert B2B web projects?

Every €1,500 landing page, €4,500 corporate website, and €9,000+ web portal we deliver includes full technical validation, 5-locale parity, and 95+ Core Web Vitals.

Static Site Generation (SSG) & ISR

April 15, 2026•4 min read

Definition and How Next.js SSG and ISR Work

Static Site Generation (SSG) is a web rendering architecture (implemented via getStaticProps and getStaticPaths in Next.js) where complete HTML pages and structured data are compiled at build time and cached across global edge nodes, while Incremental Static Regeneration (ISR) updates individual pages in the background without rebuilding the entire site.

We use Next.js SSG across all €1,500 to €4,500 landing pages and €4,500 to €9,000 corporate websites. Read our Core Web Vitals & INP optimization guide.

Why Pre-Rendered HTML Beats Database-Driven CMS Rendering

Traditional PHP/WordPress sites query a relational database on every visitor request, exposing servers to traffic spikes and SQL injection vectors. Combining SSG with an edge content delivery network, server-side rendering, and Core Web Vitals optimization cuts Time to First Byte (TTFB) below 60ms. Compare headless architectures in our Storyblok vs Sanity vs Next.js B2B guide. Execute locale normalization and JWT checks in under 5ms via edge computing and middleware routing.

2026 European B2B Benchmarks and KPIs

The table below summarizes 2026 European B2B engineering, conversion, and budget benchmarks used to evaluate production readiness:

Dimension / Metric	2026 B2B Baseline	Top-Quartile Vezert Target
Time to First Byte (TTFB)	450ms to 1,100ms (PHP/DB query)	35ms to 85ms from global edge CDN
Traffic spike resilience	Database CPU bottleneck	10,000+ concurrent requests/sec
AI & search crawler indexing	Delayed or rate-limited	Instant 100% pre-rendered HTML
