Fetch any URL as Googlebot and see the exact HTTP status, response headers, crawlability verdict, and SEO data Google extracts. Identify blocking issues before they affect your rankings.
🕷️ Try the free Googlebot Crawler Simulator →A Googlebot crawler simulator sends an HTTP request to a URL using the Googlebot user-agent string — the same identifier Google's web crawler uses when fetching your pages. The response reveals exactly what Google sees: the HTTP status code, server and caching headers, X-Robots-Tag directives, and the HTML content that Googlebot can actually parse.
This matters because your server may behave differently for Googlebot than for regular users. Some servers apply geo-restrictions, bot detection, or login walls that only trigger for certain user-agents. Content delivery networks can serve different cache layers. Cloudflare or other WAF tools may block Googlebot. A crawler simulator helps you verify that Google can access your content without obstruction.

Before publishing a new page or section, simulate a Googlebot crawl to confirm the server returns a 200 status, there are no unexpected noindex headers, and the HTML content is accessible. Catching a blocked page pre-launch is far less damaging than discovering it weeks later when rankings fail to materialise.
If a page is live but not appearing in Google Search Console or search results, a Googlebot simulation often reveals the cause: a noindex meta tag, an X-Robots-Tag: noindex HTTP header, a robots.txt block, or a server error that only occurs for bots.
Headers like X-Robots-Tag, Cache-Control, and Vary can all influence how Google crawls and indexes your content. An X-Robots-Tag: noindex in the HTTP headers (not the HTML) is a common source of silent de-indexation that only a crawler simulator reveals.
CDNs sometimes serve different content to bots versus browsers — either serving a cached stale version, a login wall, or an error page. A Googlebot simulation checks what your CDN actually returns for bot traffic.
Paste any public URL — your own page, a specific product page, or a URL you suspect is being blocked.
The tool immediately shows whether the page is crawlable and indexable. A red blocked status means Google cannot crawl or index the page as currently configured.
Review the status code (200, 301, 403, 404, 500), response time, and key headers — particularly X-Robots-Tag, Cache-Control, and server identity.
The tool shows what Google extracts from the HTML: title tag, meta description, canonical URL, robots meta tag, and H1. Compare these with what you expect to catch silent errors.

The simulator uses "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)" — the standard Googlebot crawl user-agent. For Googlebot-specific conditional responses, you can also verify using Google's official Fetch as Google tool in Google Search Console.
This is a Googlebot-cloaking scenario, often caused by: (1) bot detection at the server or CDN level (Cloudflare challenge mode, rate limiting), (2) IP-based geo-restrictions that block Google's crawl IP ranges, or (3) intentional user-agent filtering. Google considers cloaking a violation of its Webmaster Guidelines if it's used to serve different content to users vs. crawlers.
Google Search Console's URL Inspection tool shows Google's actual indexed data for the page, including rendering results. A Googlebot simulator (like this one) shows a real-time crawl result, making it faster for checking new pages, live changes, and HTTP headers. For the most authoritative indexation status, use GSC. For quick pre-launch checks, a simulator is faster.
The Googlebot crawler simulator checks HTTP-level blocking (status codes and X-Robots-Tag headers). For robots.txt rule testing, use the separate Robots.txt Checker tool, which parses your robots.txt and tells you whether a specific URL path is allowed or blocked for Googlebot.
