Robots.txt + sitemap checker

Status
Run a guarded check for /robots.txt and /sitemap.xml.
Robots.txtNot checked

0 sitemap declarations found.

Sitemap.xmlNot checked

Not checked URL or sitemap index entries found.

User-agent *Not checked

This is a basic rules summary, not a full crawler simulation.

Review notes
  • Checks only the public origin robots.txt and sitemap.xml. Local, private, reserved, non-http, and credentialed URLs are blocked.
Scope note

This checker verifies the conventional robots.txt and sitemap.xml URLs for one public origin. It does not crawl the site, execute JavaScript, validate every sitemap URL, or simulate a specific search engine bot.

Quick answer

Robots.txt + Sitemap Checker: what it checks

Robots.txt + Sitemap Checker checks robots and sitemap discovery report from site URL, robots.txt, sitemap.xml, sitemap declarations, disallow rules and sitemap URL count. The visible check method is Discovery report = guarded origin check + /robots.txt fetch + /sitemap.xml fetch + Sitemap declarations + User-agent * Disallow summary + sitemap loc count.

Check method

Discovery check method

Discovery report = guarded origin check + /robots.txt fetch + /sitemap.xml fetch + Sitemap declarations + User-agent * Disallow summary + sitemap loc count

The checker only fetches conventional robots.txt and sitemap.xml URLs for one public origin. It does not crawl the site or simulate a search engine bot.

How to use

Steps

  1. Paste a site homepage, domain, or any public URL from the site.
  2. Run the check to request the origin robots.txt and sitemap.xml files.
  3. Review robots status, sitemap status, Sitemap declarations, User-agent: * disallow rules, and sitemap URL samples.
  4. Fix missing or blocking discovery signals before submitting URLs or relying on organic indexing.

Example

Sample check

Robots declarationSitemap: https://example.com/sitemap.xml
Blocking ruleUser-agent: * with Disallow: / is flagged
Sitemap sampleFirst sitemap <loc> URLs are shown for quick inspection

Checker use

Best for

  • Use this robots.txt and sitemap checker to verify basic search discovery signals before launching, indexing, redirecting, or submitting a site.
  • Checking discovery check method with the method and assumptions visible.
  • Comparing the output with the sample check and benchmark table before using it elsewhere.
  • Browser-side link, file, format, and web utility tasks that need an output now.

Before relying on it

Check first

  • Using the robots and sitemap discovery report without checking that site URL, robots.txt and sitemap.xml, and additional inputs match the same task and context.
  • Ignoring that the checker only fetches conventional robots.txt and sitemap.xml URLs for one public origin. It does not crawl the site or simulate a search engine bot.
  • Skipping the source notes when the formula, benchmark, or warning depends on outside context.
  • Publishing a generated file or code without testing it in the real destination.

Details

What to know before using the output

These notes make the assumptions explicit, especially where the same search query can mean slightly different things.

GuardrailsPublic origin only

Localhost, private networks, reserved IPs, credentials, non-http URLs, and unsafe redirects are blocked before requests are made.

Fetch scoperobots.txt and sitemap.xml

The tool checks the conventional files at the origin root. It does not fetch arbitrary paths or crawl linked pages.

Body limitCapped scan

Large files are truncated to keep the check bounded. Use a full SEO crawler for exhaustive validation.

Benchmarks

How to read the output

This checker is a decision aid, not a fixed rule. Use the output to compare scenarios and document your assumptions. Benchmark ranges are broad planning heuristics unless this page names a specific source for the range.

Robots available: 200-range status.

A reachable robots.txt file makes crawl directives and sitemap declarations explicit.

Sitemap declared: Preferred.

Declaring Sitemap URLs in robots.txt gives crawlers a simple discovery path.

Disallow all: High risk.

Disallow: / for User-agent: * can block broad crawling unless it is intentional.

Method and limitations

Methodology and assumptions

The method, inputs, example, and limitations are shown so the check is transparent, not just a pass/fail label.

Check method

Discovery report = guarded origin check + /robots.txt fetch + /sitemap.xml fetch + Sitemap declarations + User-agent * Disallow summary + sitemap loc count

Inputs used

Site URL, robots.txt, sitemap.xml, Sitemap declarations, Disallow rules, Sitemap URL count

Limitations

Utility outputs depend on the encoded payload, file format, target app, scanner, printer, browser, and real-world testing before sharing.

FAQ

Common questions

Does this prove Google will index my site?

No. It checks basic discovery files only. Indexing can still depend on page quality, canonical tags, noindex rules, internal links, redirects, rendering, crawl demand, and Search Console signals.

Why does it only check /robots.txt and /sitemap.xml?

Keeping the fetch scope fixed avoids turning the tool into a general crawler or proxy. Sitemap URLs declared inside robots.txt are reported for manual review.

Can this replace a technical SEO crawler?

No. Use it for a fast launch sanity check. Use a crawler or Search Console when you need full URL validation, noindex checks, canonicals, redirects, and coverage diagnostics.

Do utility tools upload my payload?

Use the page notes for each tool. Browser-side utilities can generate outputs locally, but the final file or code may still reveal whatever you encode or share.

Why should I test the generated output?

Scanners, printers, file viewers, apps, and platform previews can behave differently, so test the exact downloaded output before using it publicly.

Why might another checker show a different output?

Different tools may use different rounding, assumptions, default rates, methods, formulas, or input timing. Compare the visible method and inputs before relying on the output.
