Pre‑Rendering

🛠️ What is Pre‑Rendering?

Pre-rendering is a performance optimization technique that generates a static version of a web page in advance, which is then served to the users. It ensures that users access quicker load times as the server presents pre-built pages rather than generating them on-the-fly.

⭐ Why is Pre‑Rendering Important in Technical SEO?

Pre-rendering can significantly improve site performance and SEO by reducing page load times. Fast-loading pages offer a better user experience, decrease bounce rates, and are favored by search engines — all contributing to higher rankings in search results.

⚙️ How Does Pre‑Rendering Work?

1. The server processes and creates a static version of the page.
2. This pre-rendered content is saved and ready to be served to incoming requests.
3. When a user requests the page, the server delivers the static version instantly.
4. This reduces load time since there's no need to dynamically process page scripts and resources upon each request.
