About this google crawler simulator

Our free Googlebot tester fetches any URL using the official Googlebot user-agent string and shows you exactly what Google sees when it crawls your page.

The Googlebot tester returns the rendered HTML, full HTTP response headers, extracted title, meta description, canonical tag, robots directives and Open Graph tags, the same surface area Google indexes.

Use it to debug rendering issues, verify cloaking is absent, confirm canonical tags resolve correctly, or just preview new pages before they go live.

Frequently asked questions

Does this tool actually use Googlebot?

We simulate Googlebot by sending requests with the official Googlebot user-agent string. This shows you what Google's crawler would receive, though some sites may still serve different content to verified Google IPs.

Why is my page showing different content?

Some websites use server-side cloaking or CDN-based bot detection that may serve different content to crawlers. This tool helps you identify such discrepancies.

Can I check pages behind a login?

No, this tool only crawls publicly accessible pages. Pages requiring authentication cannot be fetched.

What are robots meta directives?

The robots meta tag tells search engines whether to index a page and follow its links. Common values include 'index, follow' (default), 'noindex' (hide from search), and 'nofollow' (don't follow links).

How is this different from View Source?

Your browser's View Source shows what YOUR browser receives. This tool shows what Googlebot receives, which can differ if the server uses user-agent detection, cloaking, or dynamic rendering.

Is this Google crawler simulator free?

Yes. This Google crawler simulator is free with no signup. Each visitor can run a fair number of checks per hour.

How do I view a page as Googlebot?

Paste the URL above and run the Googlebot simulator. It fetches the page with Googlebot's own user agent, checks robots.txt and noindex, and shows the HTML Google receives, so you can view the page as Googlebot does.

What is the difference between Googlebot Smartphone and Desktop?

Google mainly indexes the mobile version of pages, so Smartphone is the default. Switch to Desktop to see if your site serves different HTML to desktop crawlers.

Does the simulator check robots.txt?

Yes. It reads your robots.txt and applies Google's matching rules to the exact page you entered, then shows the result as one step in the crawl path.

What does Content: thin, or rendered by JavaScript mean?

The raw HTML has fewer than 150 words. Either the page is thin, or most content is added by JavaScript after load, which Google may render later or not at all.

What is the X-Robots-Tag header?

An HTTP header that can tell Google not to index a page, just like a meta robots tag. It is easy to miss because it is not in the HTML, so the simulator checks it for you.

Why was my page redirected?

Common reasons are http to https, adding or removing www, or a trailing slash. A single redirect is fine, but link to the final URL directly where you can.

What is Googlebot?

Googlebot is the web crawler Google uses to discover and read pages for its search index. It comes in smartphone and desktop versions, and Google now crawls most sites with the smartphone one first.
