A URL (Uniform Resource Locator) is a web address that points to a resource like a page, API endpoint, or file, typically including scheme, host, path, and query.
URL Inspector is an online tool that helps you inspect URL.
It inspects URL and surfaces the underlying details so you can reason about it without external tooling.

Fix: Confirm the tool input requirements and paste the correct type of data.
Missing fields or partial content can block processing or produce weak results.
Fix: Provide the full required input before running the tool.
Sample or placeholder values can lead to output that looks valid but is not ready for real use.
Fix: Replace placeholders with your actual values before relying on the result.
URL Inspector checks up to 100 URLs per batch so the request completes in under a minute and doesn't hammer third-party servers. For larger sweeps, run the tool in a loop from a script.
URL Inspector fetches the raw HTML served to a crawler, which is what search engines index for the first pass. If your site relies on client-side rendering, the tool shows you exactly what Googlebot's initial render sees before it runs JavaScript.
URL Inspector sends a User-Agent string that identifies itself honestly (DevFox bot) rather than impersonating Googlebot — spoofing UAs can get a site's access flagged. If a page blocks non-browser UAs, you'll see the block clearly reflected in the output.
No. URL Inspector only makes anonymous public requests — it can't log in or carry session cookies. For auth-protected pages, use a headless browser in your own environment.
Yes. URL Inspector fetches and parses robots.txt before crawling a site and skips disallowed URLs by default. You can toggle off the check if you're auditing your own site and want to see every status code.
