# Dynamic Rendering

**Category:** SEO Crawling & Indexation | **Updated:** 2026-03-05

Dynamic rendering serves pre-rendered static HTML to search engine crawlers while serving the normal JavaScript-powered version to human users.

## What Is Dynamic Rendering?
Dynamic rendering is a server-side technique where the web server detects the requesting user agent and serves different content based on whether the visitor is a crawler or a human. Crawlers receive a fully pre-rendered static HTML version, while users receive the interactive JavaScript version.

## Why Dynamic Rendering Matters
Dynamic rendering bridges the gap between modern JavaScript frameworks and search engine capabilities. It lets you build rich interactive experiences while ensuring crawlers can access all content without executing JavaScript.

## How to Implement Dynamic Rendering
Use a headless browser (Puppeteer, Rendertron) to generate static HTML snapshots. Configure your server to detect crawler user agents and serve the pre-rendered version. Important: the pre-rendered content must match user-facing content — serving different content is considered cloaking.
