Robots.txt Builder

Last updated: April 2026

Draft a robots.txt file with allow, disallow, crawl-delay, and sitemap directives when you need a clean crawler guidance file fast.

Build a practical robots.txt file from clear allow and disallow rules without memorising syntax. This is useful when launching a new site, tightening crawler access, or adding the sitemap location to a cleaner baseline robots file.

The builder is designed for safe defaults. It helps with standard rules, but it does not replace a full crawlability review, so important paths should still be tested after publishing.

Robots.txt Builder

Sitemap Generator Create a clean XML sitemap from a list of canonical URLs for smaller sites, launches, content refreshes, and practical SEO workflows. Meta Tag Checker Audit title tags, meta descriptions, canonicals, robots directives, Open Graph fields, Twitter cards, and H1 usage from a live page or HTML. Link Checker Check a page for broken, redirected, or unreachable links with a focused QA workflow built for launches, refreshes, and internal-link cleanup.

What robots.txt is good for

A robots.txt file gives search engines and other crawlers guidance about which paths should be crawled and where the sitemap lives. It is commonly used to keep bots out of admin, search, draft, and utility paths that do not belong in normal crawl workflows.

For utility sites, a clean robots file reduces noise and makes discovery of the important public pages more predictable.

Common mistakes to avoid

  • Blocking public pages accidentally with a rule that is too broad.
  • Assuming robots.txt keeps sensitive URLs private by itself.
  • Forgetting to point crawlers to the XML sitemap after a new launch.

Best for

  • Focused SEO QA, metadata review, crawl-hint drafting, and quick content extraction.
  • Small to medium sites where a practical browser tool is enough for the task.
  • Pre-launch checks, content refreshes, and maintenance audits.

Not ideal for

  • Full enterprise crawling across very large sites.
  • Deep log analysis, server-side rendering diagnostics, or complex technical SEO suites.
  • Security-sensitive environments where live URL fetching is not appropriate.

What this tool keeps

  • Fast access to the fields and outputs most site owners actually need day to day.
  • Copy-ready XML, robots.txt, and readable content output for the next workflow step.
  • A browser-first interface with lightweight server help only where remote fetching is necessary.

What may need cleanup

  • Live page checks depend on the fetched page being publicly reachable.
  • Reference outputs still need human review before publication on a real site.
  • A focused link check is useful QA, but it is not a full-site crawl replacement.

Common errors

  • Checking a blocked staging page and assuming the tool is broken.
  • Publishing a robots.txt rule without verifying which URLs it affects.
  • Treating a generated sitemap as final without cleaning the URL list first.

Example use cases

  • Audit tags, generate crawl files, extract content, and check links before or after a publish.
  • Support a lightweight SEO workflow without buying a heavy platform.
  • Tidy individual pages and small site sections during launches or refreshes.

Sample input

A live URL, pasted HTML, or a list of canonical URLs prepared for SEO or QA work.

Sample output

A metadata audit, XML sitemap, robots.txt file, readable text block, or link-status report.

Who this is for

  • SEO specialists, developers, marketers, content teams, and site owners doing practical QA work.

Frequently Asked Questions

What is this robots.txt builder for?

It helps you draft a robots.txt file with clear allow, disallow, crawl-delay, and sitemap directives.

Does robots.txt block indexing by itself?

Not completely. It controls crawling guidance, but it is not a guarantee that a URL can never be indexed.

Should I add the sitemap URL?

Yes. If you maintain an XML sitemap, adding it to robots.txt is a good default.

Can I use this for staging or admin paths?

Yes. That is one of the common uses, but check the final rules carefully before publishing.
