Prerendering
01 Definition
Prerendering meaning: Generating static HTML of pages ahead of time so bots receive ready content.
Prerendering creates fully rendered static HTML snapshots of pages in advance or on demand, so crawlers get finished content without running JavaScript. It can be done at build time or through a service that renders and caches pages. This helps JavaScript sites stay crawlable.

Why it matters
How Prerendering fits the work
It lets JavaScript-heavy sites hand search engines complete HTML, reducing the chance that content goes unseen because a crawler did not fully render the scripts.
In context
The team prerendered 500 blog posts at build time, so search engines and social scrapers received full HTML without executing any front-end JavaScript.
Practical note
Prerendered snapshots can go stale if content changes often, so set a sensible refresh schedule. Make sure the prerendered version matches what users see to avoid mismatched content.
