GPTBot, ClaudeBot, PerplexityBot and most AI agents fetching a page for a user read the HTML the server sends and stop there. Content drawn later by JavaScript does not exist for them. My page looks fine in a browser. Why does it fail? Browsers run the JavaScript that fills the page in. Sites built as single-page apps (React, Vue or Angular without server rendering) send an almost empty page and build the rest in the browser. How do I fix a page that fails? Render it on the server or pre-render it at build time. Next.js, Nuxt, Astro and most CMSs do this already; a client-only React or Vue app needs server rendering or a pre-rendering step. ## More instant checks [**What is this site built with?** See the platform behind any website, with the proof.
