About
Prerender is a service that generates static HTML snapshots of JavaScript-rendered pages and serves them to search engine crawlers, social media bots, and other automated agents that may struggle to execute JavaScript. While modern search engines like Google have improved their JavaScript rendering, many crawlers — including those from Bing, social platforms, and AI-powered search tools — still rely on static HTML to index content accurately.
For organizations using dotCMS in headless mode with JavaScript front-end frameworks like React, Angular, Next.js, or Vue, Prerender ensures that all content is indexable and renders correctly in search results, social previews, and link previews. This is particularly important for SEO-sensitive pages where organic visibility directly impacts traffic and revenue. Prerender sits between the origin server and the crawler, transparently serving pre-rendered pages without affecting the experience for regular visitors.
