Robots.txt Checker

Your robots.txt file controls which pages search engines can crawl. A single mistake can accidentally block your entire site from being indexed. Enterno.io checks your robots.txt for syntax errors, directive correctness, and potential SEO problems.

What Gets Checked in robots.txt

The analysis covers all key aspects of the file:

  • Syntax of User-agent, Disallow, Allow directives
  • Rules for Googlebot, Yandex, and other crawlers
  • Presence and validity of Sitemap reference
  • Sections blocked from indexing
  • Conflicting Disallow/Allow rules
  • Crawl-delay directive

Common robots.txt Mistakes

Typical issues we detect:

  • Disallow: / — blocking the entire site from indexing
  • Typos in directive names
  • Wrong path to Sitemap
  • Trailing spaces or extra characters in rules

Why Checking robots.txt Matters

A single wrong character in robots.txt can stop Googlebot from crawling your site entirely. Always verify the file after site changes and when configuring a CMS or new hosting environment.

Frequently Asked Questions

How do I check a robots.txt file?

Enter the site URL into the form above. Enterno.io will automatically fetch the robots.txt from /robots.txt and analyze its contents.

Where is the robots.txt file located?

Always at the root of the domain: e.g. https://example.com/robots.txt. It must be accessible without redirects or authentication.

What does Disallow: / mean?

This directive blocks all crawlers from indexing the entire site. It's a critical error if it ends up in production — a common mistake when copying settings from a development environment.

Does every website need a robots.txt?

Yes. Without one, search engines use default crawl behavior. At minimum, include your Sitemap path — it significantly improves correct indexing.
