🕷️ Spider Simulator

See exactly what Googlebot sees when it crawls any URL — the title, meta description, the first 500 words of body text, and the number of links. Quickly diagnose JavaScript-rendering issues and content visibility problems.

What is the spider simulator?

Search engine crawlers don't see the rendered, beautified version of your page — they see the HTML returned by the server. If your site builds content with client-side JavaScript (React, Vue, etc.), what Googlebot sees may be very different from what users see. A spider simulator shows the crawler's view: stripped of styling, isolated to text and links, ready for analysis.

How does this spider simulator work?

Enter a URL. The tool fetches the raw HTML through a CORS-friendly proxy, extracts the title, meta description, body text content (concatenated, no HTML), and link count. You see the page as a text-first crawler does — useful for diagnosing missing content, hidden text, or JavaScript-only rendering.

When should you use this tool?

Use it when troubleshooting why a JS-heavy page won't rank, when verifying that critical content (product descriptions, pricing, reviews) is in the server-rendered HTML, when auditing a competitor's content depth, and after deploying a CMS or framework change.

Tips & best practices

If your important content (CTAs, product info, key headings) doesn't appear in the spider view, your SEO is at risk. Server-side rendering (SSR) or pre-rendering fixes this. Pair with Google Search Console's URL Inspection tool — it renders the page in a real Chromium and shows you the rendered HTML Googlebot saw.

Frequently asked questions

Does Google really only see this?

Modern Googlebot can execute JavaScript, but with delays and budget constraints. For best results, ship critical content in initial HTML.

Why is my heading missing from the view?

Likely because it's rendered by client-side JavaScript. Server-render or pre-render to fix.

How does this differ from View Source?

View Source shows the raw HTML in your browser. Our tool fetches it server-side, bypassing CORS, so you can audit any URL — including ones that block your local browser.
