MyIPScan

Website Security and SEO Tool

Robots.txt Checker

Fetch a public robots.txt file, parse crawler directives, review sitemap declarations, and spot common SEO configuration signals. This is a limited syntax and accessibility check, not a full crawler simulation.

Direct answer

Robots.txt Checker: answer first

Check a public robots.txt file, parse user-agent rules, sitemap declarations, crawl-delay, and common SEO signals with safe limits. Use the result as an observable public-signal check with stated limitations, not as an absolute guarantee.

Last updated

Check robots.txt

Enter one public domain or HTTP/HTTPS URL. MyIPScan will check the root robots.txt file only.
Technical response details (optional)
Trust note: this server-assisted check fetches only one public robots.txt URL, blocks private/internal targets, and does not crawl the site.


What this checks
MyIPScan normalizes the input to the site root, fetches /robots.txt with strict limits, and parses common directives including User-agent, Allow, Disallow, Crawl-delay, Sitemap, and Host.
What the results mean
A missing file is not always a problem, but it means crawlers do not receive explicit sitemap or crawl guidance from robots.txt. A global Disallow: / can block broad crawling when placed under User-agent: *. Sitemap declarations help crawlers discover canonical sitemap URLs.
How to use this tool
  1. Enter a public domain or URL such as example.com.
  2. Review the HTTP status, parsed directive groups, sitemap declarations, and warning notes.
  3. Use AI/Search Visibility Scanner, Sitemap Checker, Canonical / Noindex Checker, Meta Title / Description Checker, HTML Heading / Content Structure Checker, Structured Data / JSON-LD Validator, Open Graph / Social Preview Checker, Redirect Checker, SSL Certificate Checker, DNS Lookup, and Security Headers Checker for nearby website diagnostics.


FAQ
What is robots.txt?
robots.txt is a public text file at the root of a site that gives crawler guidance such as User-agent, Allow, Disallow, Crawl-delay, and Sitemap directives.
Does robots.txt block indexing?
It can block crawling, but a URL may still appear in search if discovered elsewhere. Use page-level noindex or headers when indexing control is required.
What happens if robots.txt is missing?
Many sites work without one. Missing robots.txt means crawlers do not receive explicit crawl guidance or sitemap declarations from that file.
Should robots.txt include sitemap.xml?
A Sitemap directive is useful because it points crawlers to canonical sitemap URLs, but it is not the only way crawlers discover sitemaps.
Can robots.txt hide private pages?
No. robots.txt is public and should not be used to protect private pages. Use authentication, authorization, and proper indexing controls for sensitive URLs.


Limitations
This tool parses common robots.txt syntax and flags obvious signals, but it does not fully emulate Googlebot or every crawler-specific rule precedence model. It also does not crawl pages or verify whether indexed URLs exist. See the methodology for how MyIPScan labels limited checks.

Robots.txt Checker: what this tool does

    
Fetches and parses a public robots.txt file, including user-agent rules, sitemap declarations, crawl-delay, and common SEO signals.

  

  

    

      
How to use

      
  1. Enter one public HTTP/HTTPS URL or domain accepted by the tool.
  2. Review final URL, source coverage, confidence, and the top fixes before raw details.
  3. Retest after one hosting, DNS, redirect, header, robots, sitemap, or schema change.

    

    

      
What the result means

      
Treat website, TLS, redirect, header, crawlability, and structured-data outputs as public HTTP/DNS evidence. These tools do not run vulnerability scans or guarantee indexing.

    

    

      
Limitations

      
  • This tool reports observable signals only; it is not a guarantee or certification.
  • Uses /api/robots-txt with one public /robots.txt GET request, DNS preflight, redirect revalidation, response-size cap, and TTL cache.
  • Results can change after VPN reconnects, DNS propagation, browser updates, cache changes, or provider configuration changes.
