What is the Robots.txt Validator?
What the Robots.txt Validator does
Use the free Robots.txt Validator to validate robots.txt syntax and test URL allow/block rules.
That is the whole scope of the page. It sits in SEO & Web Tools, the group for research, audits, schema & ai seo. The Robots.txt Validator only does the job in that first sentence.
Robots.txt Validator runs in your browser. The file or the figures stay on your device, and the free plan does not ask you to create an account.
When a Robots.txt Validator is the right page
Use it when you have a URL, a keyword, or a draft and you need the check described on this page.
Open it when you need to validate robots.txt syntax and test URL allow/block rules. If you need a different output, pick the tool whose description names that output.
How to use the Robots.txt Validator
Paste the real URL or the real draft. A made-up example will not describe your site.
Run it once with the values you have. The result should line up with this promise: Validate robots.txt syntax and test URL allow/block rules. Change one field if you want a second case, and keep the other fields the same so you can see what moved.
How to read the result
Use the result as a list of things to verify in the page source or in Search Console, not as a ranking promise.
Keep the units, the dates, and the file type that the form showed. A number from the Robots.txt Validator is ready to copy only after you have checked it against the labels on this page.
What the Robots.txt Validator leaves out
The tool does not control Google, and a score here is not a position in search results.
Anything the description does not mention is outside this tool. Use the result as the estimate or the file this page promised, then check the source that actually applies to your bank, school, client, or project.
The next tool
Other tools in SEO & Web Tools include Keyword Density Checker, Robots.txt Generator, UTM Builder, LLMs.txt Generator, IBAN Validator and .env Validator. Open the one whose description matches the next job.
