Website URL *

We will try to load https://domain/robots.txt for you.

Formatted robots.txt

Fetch a robots.txt above, or paste its content manually.

Note about fetching: many websites block cross-site (CORS) requests, so the automatic fetch may fail even when the file exists. If it does, just open /robots.txt in your browser, copy the text, and use the Paste manually tab.

Sobre Robots.txt Checker

What is the Robots.txt Checker?

The Robots.txt Checker is a free online SEO tool that fetches the robots.txt file of any website and shows you exactly what search engine crawlers are allowed and forbidden to visit. The robots.txt file sits at the root of every domain and acts as a set of instructions for Googlebot, Bingbot and other crawlers, telling them which folders to crawl and which to leave alone. A single misplaced Disallow: / can wipe your entire site from Google, so knowing what your file actually says is critical.

This tool retrieves the live file in seconds and presents it in a clean, readable view with each rule explained in plain language. It highlights common dangers such as blocking CSS and JavaScript files, accidentally disallowing the whole site, or pointing to a missing sitemap. Whether you are auditing your own site or researching a competitor, you get the full picture without digging through raw text.

How to Use the Robots.txt Checker

Enter the domain: Type the website address, for example example.com. No need for the full robots.txt path.
Click Check: The tool fetches the live robots.txt file from the domain root.
Read the rules: Review each User-agent block with its Allow and Disallow directives explained.
Spot problems: Look for warnings about blocked resources, sitewide disallows or missing sitemaps.
Fix and recheck: Update the file on your server, then run the checker again to confirm the fix.

Key Benefits

Catch costly mistakes: Instantly see if you are accidentally blocking Google from your whole site.
Plain-language rules: Every directive is explained so non-developers understand it too.
Check any domain: Audit your own sites or research how competitors handle crawling.
Sitemap detection: Confirms whether your XML sitemap is declared and reachable.
Free and instant: No signup, check as many domains as you like.

Pro Tips

Never block CSS and JS: Google needs these to render pages correctly, and blocking them can hurt rankings.
Use it after every site change: Migrations, redesigns and staging pushes are the classic moments when a bad robots.txt goes live.
Remember it is public: Anyone can read your robots.txt, so never list sensitive admin paths in it. Use proper authentication instead.
Pair with Search Console: Google Search Console shows you how Googlebot actually interprets your file.

Frequently Asked Questions

Where is the robots.txt file located?

Always at the domain root, for example https://example.com/robots.txt. Crawlers look there and nowhere else.

Does robots.txt improve my rankings?

Not directly, but a correct file ensures crawlers spend their budget on your important pages instead of junk URLs.

What happens if a site has no robots.txt?

Crawlers assume everything may be crawled. That is usually fine, but you lose the ability to block staging areas or thin pages.

Can robots.txt hide a page from Google?

Only partially. Blocked pages can still appear in results if other sites link to them. For true removal, use noindex or password protection.
