Static Site Generation (SSG) is a web development approach where a site’s pages are fully pre-rendered into complete HTML files at build time, rather than being generated dynamically on each individual request.
SSG generally offers the fastest possible loading performance and the most reliable SEO outcomes among modern rendering approaches, since search engines receive complete, ready-to-index HTML immediately without needing any server-side or client-side rendering delay.
The main trade-off is that content updates require rebuilding the affected pages, making SSG best suited for content that doesn’t need to change on every single request, such as marketing pages and blog content.
We recommend SSG where appropriate within our Technical SEO service.
