What is the difference between timed ISR and on-demand ISR in Next.js?

Timed ISR re-renders a page in the background after a fixed revalidate interval (e.g., 3600 seconds), whereas on-demand ISR invalidates the exact path immediately via an authenticated webhook.

When should a B2B website use ISR instead of pure SSG?

Use pure SSG for core marketing pages and ISR for large product catalogs, multi-region job boards, or documentation hubs where editors publish updates throughout the day.

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.
