What it means

Primary content is present in the initial HTML without executing JavaScript.

AI crawlers (GPTBot, PerplexityBot, ClaudeBot) largely do not run JS. A CSR-only shell is invisible to them.

✗

<div id="root"></div> + <script src="bundle.js"> — empty HTML until hydration.

✓

Headings and paragraphs rendered server-side; JS only enhances interactivity.
