Incremental Static Regeneration
A web architecture pattern that allows static pages to be updated after deployment without rebuilding the entire site.
BasaltHQ uses ISR extensively across its public-facing surfaces to serve 15,000+ programmatic location and industry pages at edge-network speeds. When Googlebot crawls basalthq.com/locations/tokyo for the first time, the server renders the page, caches it at the edge, and serves it as static HTML to all subsequent visitors for a configurable period (typically 7 days). This achieves Time-To-First-Byte (TTFB) under 50ms globally while keeping content fresh. ISR is the key to scaling programmatic SEO without sacrificing Core Web Vitals performance.
