Free Robots.txt Checker

Instant online robots txt checker for any public domain. See whether the file exists, if crawlers are blocked site-wide, which Sitemap URLs are declared, and how common AI bots are treated — free, no signup.

How it works

  1. 01

    Enter a domain or full URL

    We resolve the host and request /robots.txt over HTTPS when available (with a sensible fallback).

  2. 02

    Parse crawl rules and Sitemap lines

    The response body is scanned for User-agent groups, Disallow / Allow directives, and Sitemap: URLs.

  3. 03

    Flag high-impact and AI-bot policy

    We highlight crawl-all blocks and known generative crawler user-agents so you can verify intent at a glance.

What this robots.txt checker reports

Built for technical SEO reviews and quick pre-launch checks — not a full Search Console crawl report.

  • HTTP status and whether robots.txt was found
  • Site-wide Disallow patterns that block all crawlers
  • Sitemap directives listed in the file
  • Presence of rules for popular AI crawlers (e.g. GPTBot, ClaudeBot)
  • Raw file preview so you can audit the exact text crawlers see

robots.txt vs noindex (common mix-up)

robots.txt controls crawl access at the path level. A Disallow can stop a bot from downloading a URL, but it is not a substitute for telling Google not to index a URL that was already discovered. Indexing directives live in meta robots and X-Robots-Tag.

After you confirm robots.txt, run the Noindex Checker on key templates (staging, thank-you pages, filtered listings) and the full website SEO checker for Meta, Structure, Technical, and GEO together.

When to run a robots txt checker

Use this free robots.txt checker after CMS or CDN changes, before a migration, when organic traffic drops after a deploy, or when you intentionally block AI training bots and need proof the public file matches policy. Always keep a Sitemap line pointing at your current XML sitemap when you want discovery help.

Frequently asked questions

What does a free robots.txt checker do?
It fetches the public robots.txt for a domain (usually https://example.com/robots.txt), shows whether the file exists, and highlights high-impact rules such as Disallow: / for all user-agents, Sitemap lines, and blocks aimed at AI crawlers like GPTBot or ClaudeBot.
Is robots.txt the same as noindex?
No. robots.txt tells crawlers which paths they may fetch. Indexing of a URL is also controlled by meta robots and the X-Robots-Tag HTTP header. A page can be crawlable but still noindex — check both.
Why check AI crawler rules in robots.txt?
Many generative engines honor robots.txt for training and browsing bots. Blocking GPTBot, ClaudeBot, or similar agents is a deliberate policy choice. This checker surfaces those user-agent blocks so you can confirm what you intended to publish.
Does this tool submit my site to Google?
No. It only performs a live HTTP fetch of robots.txt from our servers and displays the result. Nothing is submitted to Search Console or any search engine.
Do I need an account?
No. TheSeoSoul robots txt checker is free with no registration. For a full Meta / Structure / Technical / GEO audit of the same domain, use the website SEO checker on the homepage.
