AI Raw HTML Viewer
See the HTML your server actually returns, before any JavaScript runs. That first pass is what the retrieval crawlers read — OAI-SearchBot, Claude-SearchBot and PerplexityBot, the agents that decide whether an engine can cite you.

Rendering is one piece of it. Run a full audit to check AI crawler access, structured data, indexing and performance across the site.

Unlike a browser, the crawlers that decide AI citations — OAI-SearchBot, Claude-SearchBot, PerplexityBot and their user-initiated counterparts — are not guaranteed to execute client-side JavaScript. They fetch the initial raw HTML and extract text and links from that. Googlebot does render JavaScript, but on a second pass that can lag the first by a long way, so content that only exists after hydration is read late, if at all.
Common Pitfalls for Single Page Applications (SPAs):
- Empty Containers: Returning an empty
<div id="app"></div>without Server-Side Rendering (SSR) causes AI crawlers to see a blank page. - Missing Meta Tags in Initial HTML: If
<title>and<h1>tags are populated dynamically by client-side JS, AI models miss key context. - Recommended Solution: Implement SSR (Next.js / Nuxt / Laravel Blade) or Prerendering to deliver full HTML content to crawlers. Getting read is step one; what decides whether you get cited is step two.
Frequently Asked Questions
Do AI search crawlers execute JavaScript like browsers do?
The crawlers that decide citations — OAI-SearchBot, Claude-SearchBot, PerplexityBot and their user-initiated counterparts — are not guaranteed to execute client-side JavaScript, and fetch the raw HTML instead. GPTBot and ClaudeBot are training-only agents and do not affect citation either way. Googlebot does render JavaScript, but on a later pass. If your content relies purely on client-side JS rendering, AI crawlers will see a blank page.
How can I make Single Page Applications (SPAs) accessible to AI crawlers?
Use Server-Side Rendering (SSR), Static Site Generation (SSG), or Dynamic Rendering (e.g., Next.js, Nuxt, Prerender.io) to serve fully rendered HTML to bots.
